6 Best GPX Editors and Viewers for Android in 2026

A GPX file can look fine until one bad GPS point throws the track across a river, the recorded drive home remains attached to a hike, or a campsite waypoint lands on the wrong side of a valley. For fixing those problems on a phone, Tracklia is the best overall GPX editor for Android because it can change individual points, waypoints, tracks, and routes, then export the result as GPX. If the file only needs opening and inspection, GPX Viewer is the best overall GPX viewer for Android because it displays routes, waypoints, elevation, and available sensor data without pretending to offer point editing.

Choose OsmAnd when offline route creation and navigation matter as much as editing. Pick Locus Map for detailed track repair and a deeper outdoor map library. For a free edit without installing an app, gpx.studio works in an Android browser. The deciding question is whether the file must change. A viewer is simpler and safer for checking a downloaded route; an editor is necessary when points, waypoints, segments, or direction must be corrected.

GPX Editor vs Viewer, Planner, Recorder, and Navigation App

A GPX viewer draws a file's tracks, routes, and waypoints on a map. It may show distance, elevation, speed, heart rate, or cadence without changing any underlying coordinates. GPX Viewer is especially good at this job.

A track recorder creates a breadcrumb trail from the phone's location sensor. Recording a new trip is not the same as correcting an imported trip. A recorder may export GPX while offering no way to remove a bad point afterward.

A route planner creates a future path from shaping points. Those points may be converted into a dense GPX track when exported. A navigation app follows that path and gives directions. Neither label guarantees that the app can edit every original track point.

A waypoint manager works with individual places such as a trailhead, water source, or campsite. Waypoints are separate from route points and track points. Renaming a campsite does not change the track line, and moving a route-shaping point does not necessarily move a standalone waypoint.

A genuine GPX editor changes the data and saves a new GPX file. For this comparison, direct point movement, trimming, splitting, joining, reversing, waypoint changes, and export count more than map popularity. A browser editor can qualify when it performs those actions on Android, even though it is not a native app.

1. Tracklia - Best Overall GPX Editor for Android

Choose Tracklia when the file itself needs work, not merely a place on a map. Its current Android app can import tracks, routes, and waypoints; add, insert, update, or delete points; change waypoint locations and descriptions; split a long track; join several tracks; reverse direction; and export the changed data to GPX. That set of confirmed actions makes it the closest match for the search term.

The most useful workflow is concrete: import Downloads/morning-hike.gpx, remove the car journey before the trailhead, drag the misplaced point back to the path, rename the water waypoint, check the elevation graph, and use Export > GPX to save a corrected copy. Tracklia can also create a new measured track, record a trip, and provide simple position-following navigation.

What you get

• Direct editing of track points, routes, and waypoints
• Tools for splitting, joining, reversing, and exporting GPX files
• Basic recording, navigation, and limited offline maps

What you don't get

• The complete editing toolkit or unlimited offline maps without Pro
• A guarantee that every timestamp, sensor field, or proprietary extension will survive export
• Advanced turn-by-turn navigation for demanding offline trips

Tracklia's official Google Play listing was updated on June 15, 2026. The free app contains ads and in-app purchases. Its official pricing page places advanced track editing, merging, splitting, reversing, unlimited offline maps, custom waypoint icons, photo attachments, and extra export formats in Pro. At the time of research, Pro was listed at €9.99 per year or €29.99 lifetime; Google Play may show a different local price with tax.

The free tier still imports GPX, displays tracks, records basic GPS data, provides basic waypoint management, exports GPX, and allows limited offline maps. This makes it useful for inspection before payment, but someone searching specifically for a full editor should expect the Pro upgrade.

Tracklia stores imported map data in its own My Maps area and does not advertise cross-device cloud synchronization. Neither its Play listing nor pricing page documents a separate sign-in for local import, editing, and export. That local-first organization is convenient until the phone is replaced or the app has a problem, so export important edits to a normal folder instead of leaving the only copy inside the app.

Location access is relevant for Record track and following your position. It is not a reason to grant permanent location access before you need those functions. Google Play's data-safety label says the app may collect app activity, app information, performance data, and device identifiers, and may share device identifiers with third parties.

There is also a GPX-preservation caveat. Tracklia lets you choose which tracks, routes, areas, and waypoints to import, then creates or updates an export. Its public documentation does not promise a byte-for-byte round trip for timestamps, sensor data, links, namespaces, or vendor-specific extensions. Keep the original file and inspect a critical export before deleting it.

Main limitation: the best editing and offline-map features are paid, and navigation is intentionally basic. Choose OsmAnd or Locus Map when the edited file must also guide a long offline trip.

2. OsmAnd - Best for Offline Route Editing and Navigation

OsmAnd is the better choice when a GPX edit is preparation for offline navigation. Its Android Plan a route screen is a real editor, not only a planner: it can open an imported track, move, add, and delete points, trim everything before or after a selected point, split and rejoin segments, reverse the route, filter inaccurate GPS points, and save the result as GPX.

The relevant path is Menu > Plan a route > Open existing track / Import track. OsmAnd connects points by a routing profile or straight lines, so it can repair a road or trail route rather than forcing every edit into a direct line. The editor also works offline after the required map data is downloaded.

What you get

• Track-point editing, trimming, splitting, joining, and reversing
• Offline maps, route planning, navigation, and GPX export
• Routing profiles that can reconnect edits along roads or trails

What you don't get

• A lightweight interface for occasional one-point corrections
• The strongest tools for editing standalone waypoint names, descriptions, and symbols
• A guarantee that road snapping will preserve the original geometry, elevation, or activity statistics

OsmAnd's official point and segment documentation explains an export decision that other roundups often miss. Full track data keeps OsmAnd navigation information for later editing, while Simplified track removes route instructions and leaves cleaner geometry for other apps. OsmAnd documents that waypoints remain in a simplified export, but the extra navigation data does not.

Attaching an old recording to nearby roads is also a destructive transformation, not cosmetic map snapping. OsmAnd warns that it may recalculate geometry, elevation, distance, ascent, speed, time in motion, and duration. Save the attached version under a new filename if the original timestamps or fitness statistics matter.

The free Android version imports and exports GPX, plans routes, records trips, and supports offline navigation. Its current limit is seven regional map downloads or updates. According to the official Android purchase table, Maps+ costs $14.99 per year or $69.99 as a one-time purchase in the US, while OsmAnd Pro is $5.99 per month or $39.99 per year. Prices vary by region.

OsmAnd's purchase documentation ties an account to Cloud backup, synchronization, and purchase restoration rather than ordinary local planning, file import, and navigation. The app is open source, and its Play listing says the developer does not share data with third parties, although its label says several data types may be collected depending on the features used.

OsmAnd can store favorites, markers, and GPX waypoints, but its Plan a route documentation concentrates on route and track points. Choose Tracklia or Locus Map when changing standalone waypoint names, descriptions, and symbols inside the exported file is the main job.

Location permission matters for navigation and recording. Background access is relevant only if recording or guidance must continue with the screen off. Editing an already imported file does not require a fresh GPS position.

Main limitation: OsmAnd presents a large number of map, routing, and plugin controls. Tracklia is more direct for a one-off track correction, and Locus Map gives finer visual help when moving a single bad point.

3. Locus Map - Best for Precise Track Repair and Outdoor Map Work

Locus Map is the strongest choice here for correcting a small section of a track against an outdoor map. Its dedicated track editor can cut an inner section, remove everything before or after a point, insert a gap, split a track, merge tracks, delete a bad track point, and move or add track points with a magnified positioning view.

That magnifier matters on a phone. A finger covers the coordinate it is trying to place, while the enlarged view provides visual separation between the touch and the target. For a GPS spike beside a narrow trail, this is more useful than a long list of general mapping features.

What you get

• Precise point placement with a magnified editing view
• Tools to cut, split, merge, reverse, and reroute tracks
• Outdoor maps plus detailed track and waypoint management

What you don't get

• A simple interface designed only for quick occasional corrections
• Every map, cloud, and advanced outdoor feature in the free tier
• A documented guarantee that every proprietary GPX extension survives an edited export

The official Locus Map track-editing manual separates two workflows. Edit track changes recorded geometry point by point. Re-route opens an imported route or track in the planner, where shaping points can be moved, navigation commands changed, and the path extended or shortened. Locus also manages standalone points, including their name, description, coordinates, icon, and attachments.

Multiple tracks can be selected in My Library and joined in a chosen order. A copy can be reversed, but Locus warns that old navigation commands may be wrong after reversal, especially where traffic rules matter. Reversing geometry does not magically rewrite every turn instruction.

Locus Map's current GPX export documentation supports points, tracks, multiple tracks, routes, GPX-version selection, and optional navigation commands. It states that valid GPX tags are supported. Even so, the documentation does not explicitly guarantee every proprietary extension from Garmin, Strava, or another vendor after an edited round trip, so retain the source file.

The Google Play app is free with ads and in-app purchases. New users receive three free LoMap downloads, while Premium Silver and Gold add map, sport, web, cloud, and offline features. Current pricing is shown by region inside the app. A Locus account is required for Premium, the Locus Store, cloud services, and live tracking, not for every local GPX action.

One current Android detail is easy to miss: Locus stopped supporting direct Google Drive export in September 2025 after its Drive access was denied. Device storage, Dropbox, OneDrive, Android sharing, and other document providers remain available.

Location access serves recording, guidance, navigation, and live tracking. A local geometry edit can be done without sharing live position. Google Play says Locus may collect location, personal information, and other data, while declaring that it does not share data with third parties.

Main limitation: Locus Map has a deeper learning curve and a tiered map ecosystem. It is a good long-term outdoor platform, but more app than someone needs to delete three points and leave.

4. gpx.studio - Best Browser-Based GPX Editor on Android

Use gpx.studio when installing an app is unnecessary or impossible. Open it in Chrome, load a GPX file through Android's picker, and it can move, insert, or delete track points; crop or split a track; reverse it; change a loop's start; manage waypoints; reduce point count; rearrange segments; merge files; and download a new GPX.

It is also the most transparent option here about sensor fields. During export, the user chooses whether to include time, temperature, heart rate, cadence, power, and surface data. When new track points are inserted, gpx.studio fills those sensor fields with averages. When files are merged, it may extend missing values and shift timestamps to keep time increasing. Those choices help create a usable file, but they are transformations rather than preservation of the original samples.

What you get

• Track-point editing, cropping, splitting, reversing, merging, and waypoint tools
• Control over which common sensor fields are included during export
• A free browser editor that does not require an app or account

What you don't get

• Normal map, elevation, search, and routing use without an internet connection
• A comfortable precision-editing experience on every small phone screen
• Untouched sensor values or timestamps when points are inserted or files are merged

The official gpx.studio guide and privacy policy says GPX files are read once, processed in the local browser, and not stored on its server. No account is needed for local load and download. Connecting Google Drive is optional and uses the user's Google account.

Local file parsing does not mean the whole service is offline. The site says route requests go to its servers, while Mapbox APIs provide maps, elevation, and geocoding. A connection is therefore part of normal use, and the browser page must load before editing.

The editor is free and ad-free. On a tablet, landscape mode gives the map, elevation profile, file tabs, and editing controls more room. On a small phone, precise point work is less forgiving; recent mobile user discussion reports accidental point additions and map rotation while trying to edit. That is a reported experience, not a measured result from this article.

Main limitation: its desktop-shaped interface is crowded on a phone and it is not an offline navigation app. Use Tracklia for repeated phone editing or OsmAnd when the result must guide the trip.

5. OpenTrackEditor - Best Free Open-Source Track Geometry Editor

OpenTrackEditor is the cleanest specialist choice for someone who wants free, open-source Android software and mainly cares about track shape. It imports and exports GPX and KML, creates tracks, moves, adds, and deletes individual points, joins tracks, reverses a track or segment, and applies point-reduction filters.

The app is free, has no ads, and does not require a subscription or document an account system. Its official GitHub repository is licensed under GPL-3.0 and documents Android 7.0 or later. The Google Play release was last updated on November 6, 2025, so it remains recent enough to include, though development is much smaller than OsmAnd or Locus Map.

What you get

• Free, ad-free, open-source GPX and KML editing
• Tools to move, add, delete, join, reverse, and reduce track points
• A focused geometry editor without a subscription or documented account requirement

What you don't get

• Finished elevation, timestamp, file-repair, or advanced statistics tools
• Clearly documented management of complete standalone waypoint metadata
• A mature outdoor mapping and navigation system

There is an important boundary in the project's own roadmap. Elevation graphs, timestamp extraction and editing, custom map layers, file repair, a dedicated cut tool, and richer statistics are planned rather than finished, even though the Play description broadly mentions cutting tracks into segments. Because those primary sources conflict, do not choose it specifically for trimming. It should also not be the first choice for an activity file where time, elevation, heart rate, cadence, temperature, and vendor extensions must survive a round trip.

Its documented point tools operate on the points that form tracks. Full standalone waypoint metadata management is not clearly documented. Choose Tracklia or gpx.studio if a file contains named campsites and descriptions that need editing as carefully as the route line.

Privacy wording also needs a cautious reading. The Play description says no tracking or data collection, but Google Play's separate data-safety label says app activity may be collected, is not encrypted, and cannot be deleted. Those statements do not line up neatly. The source code is available for inspection, but this article does not treat the marketing sentence as a verified privacy audit.

No location permission is needed to change coordinates already present in a file unless the app uses location for a separate map function. OpenTrackEditor does not position itself as a recorder or navigation app, which keeps the workflow focused.

Main limitation: it is a young geometry editor, not a complete outdoor mapping system, sensor-data editor, or waypoint database. Keep an untouched original and compare exports when anything beyond latitude and longitude matters.

6. GPX Viewer and GPX Viewer PRO - Best Overall GPX Viewer for Android

Install GPX Viewer when the first job is understanding a file, not changing its geometry. It opens GPX tracks, routes, and waypoints; handles multiple files; and can display distance, elevation, speed, cadence, heart rate, power, and temperature when those values exist. That makes it a better first look at a fitness export than some editors that discard fields they do not understand.

Despite the name occasionally being associated with editing, the current Android documentation sets a firm limit. GPX Viewer PRO can edit track and route metadata such as name, description, type, and links, but the track start, end, point count, and segment count are non-editable. For waypoints, coordinates and elevation are also non-editable. It is not the app for dragging a bad point back onto the road.

What you get

• Clear inspection of tracks, routes, waypoints, elevation, and available sensor data
• Support for opening and comparing multiple GPX files
• Offline maps, recording, and GPX export in the paid PRO app

What you don't get

• The ability to move, add, or delete track points
• Coordinate or elevation editing for waypoints
• A guarantee that exported files preserve every proprietary extension

The free GPX Viewer Android app contains ads and in-app purchases. The separate GPX Viewer PRO listing was $8.99 in the US at research time. PRO adds offline vector maps, track recording, GPX export, and other functions. The app was updated on July 3, 2026.

The official GPX Viewer manual says recording needs location permission. Recording with the screen off may also require background location and exemption from battery optimization. Merely opening a file and inspecting its existing data is a different task and should not need continuous background location.

The official local-file workflow does not state a sign-in requirement. Trackbook features are a separate planning and storage workflow, and files imported from Trackbook must be edited there. Google Play says the free app may collect personal information and app activity and may share app activity, performance information, and device identifiers.

PRO can export selected tracks, routes, and waypoints to a new file, but the manual does not guarantee preservation of vendor-specific extensions. Since the app's main value is inspection, keep the source file and use the exported copy only when metadata or recorded data actually needs to leave GPX Viewer.

Main limitation: it edits descriptions and other metadata, not the coordinate sequence. Use it to decide what a file contains, then send the file to Tracklia, Locus Map, OsmAnd, or gpx.studio for geometry changes.

GPX Editor and Viewer Comparison for Android

Best GPX App by Use Case

Choose Tracklia if you need to move incorrect track points, trim an unwanted section, update a campsite waypoint, reverse a track, or combine tracks in one native Android app.

Choose OsmAnd if you are creating a cycling or driving route that must be edited, exported, and followed without mobile data. Keep Full track data for OsmAnd and use Simplified track for wider compatibility.

Choose Locus Map if a recorded hiking track needs careful point repair against a detailed outdoor map, or if tracks and waypoints will become part of a larger offline library.

Choose GPX Viewer if an attachment only needs to be opened, checked, and followed. It is also the better inspector for sensor fields that a lightweight editor may ignore.

Choose OpenTrackEditor if the requirement is free open-source geometry editing and the file does not depend on timestamps, elevation charts, sensor extensions, or detailed waypoint metadata.

Use gpx.studio if you need a quick browser edit, a crop, a merge, timestamp changes, or control over exported sensor fields. A tablet is a better canvas than a small phone.

Use the site's GPX Merger if the only task is joining several GPX files. It combines tracks, routes, and waypoints locally in the browser without making you learn a complete map application.

For private location data, prefer local files, avoid optional cloud sync, keep location permission off during ordinary editing, and remove the beginning and end near home before sharing.

How These Applications Were Selected

The ranking gives the most weight to matching the application to the job. Editors were assessed on changes that survive as a new GPX file: moving or deleting points, trimming, splitting, joining, reversing, editing waypoints, creating a route, and exporting. Viewers were assessed on file opening, track and route display, waypoint handling, elevation and sensor inspection, offline maps, and whether their editing limits were stated clearly.

Android availability and recent maintenance were checked through current Google Play listings, official release dates, and official GitHub activity. Pricing came from current developer pricing pages or store listings. Region-specific store amounts are identified rather than presented as worldwide prices.

GPX import, export, offline behavior, accounts, permissions, and editing boundaries were checked against product manuals and support pages. Products were left out when their strongest Android workflow duplicated a selected app, when geometry editing could not be confirmed, or when current maintenance was unclear.

The six remaining choices are not six versions of the same recommendation. Tracklia is the direct editor; OsmAnd is the offline route editor and navigator; Locus Map is the detailed outdoor track editor; gpx.studio is the browser editor; OpenTrackEditor is the open-source specialist; and GPX Viewer is the dedicated viewer and inspector.

Research Methodology and Evidence Limits

This is a researched comparison completed on July 26, 2026, not a hands-on app test. No app was installed on an Android device for this article, and no edited export was compared element by element with its source. That is why there are no device names, loading times, battery figures, file-size claims, or statements about touch performance presented as measured facts.

Official Google Play listings, product manuals, pricing pages, privacy disclosures, and source repositories were prioritized. Current specialist discussions were used to find missing candidates and recurring mobile concerns, but not as the source for prices or confirmed features.

No selected vendor provides a complete public matrix proving preservation of every GPX element and extension after every kind of edit. Claims about waypoint names, descriptions, timestamps, elevation, sensor values, route instructions, metadata, symbols, links, namespaces, and vendor extensions are limited to what each source actually documents.

For a Garmin, Strava, Wahoo, or fitness-lab export, the prudent method is Save as new, reopen the result in a second viewer, and retain the untouched source. A valid-looking map line does not prove that heart rate, cadence, temperature, timestamps, or proprietary extensions survived.

Android-Specific GPX Advice

Open an attachment without losing the original

From email or a messaging app, download the attachment first when possible. In the editor, use Android's file picker to open Downloads/route.gpx. Android's Storage Access Framework can show local storage and document providers such as Google Drive without giving the app unrestricted access to every folder.

The Android share sheet is useful for handing the same file from GPX Viewer to an editor. Some apps import a copy into private app storage, while others keep access to the selected document. Because that behavior differs, export the result deliberately to Downloads or Documents under a new name.

Save a copy before changing geometry

Use a name such as route-edited.gpx instead of overwriting route.gpx. Splitting, joining, snapping to roads, simplifying points, and reversing a route can change more than the visible line. They may alter segment structure, times, elevation, navigation instructions, or sensor values.

Newer Android versions restrict direct access to other apps' private folders, including much of Android/data. Use the system picker rather than moving files into protected folders with a third-party file manager.

Use a tablet for dense point work

A phone is adequate for trimming the beginning or end, deleting a visible spike, or moving one waypoint. A tablet provides more map area for long routes, elevation graphs, split points, and a side panel at the same time. A stylus can improve placement, but only if the app accepts it as ordinary touch input; no special stylus support was confirmed for these recommendations.

Separate offline maps from offline editing

A GPX file can be edited locally while the basemap is blank. Offline editing means the file operation works without a network; offline maps mean the geographic tiles or vector data were downloaded in advance. gpx.studio processes the file in the browser but still relies on online map and routing services during normal use.

Before leaving coverage, download the required region, open the GPX once, and switch the phone to airplane mode for a dry run. That checks the map package and route availability without claiming a performance result.

Treat live recording as a different permission decision

Opening a GPX attachment does not need the phone's current position. Recording a trip, following the position marker, or continuing guidance with the screen off does. Android may require background location for continuous recording, and long-running location updates can reduce battery life.

Grant Allow only while using the app for ordinary navigation when it is enough. Use Allow all the time only when the chosen recorder documents that background operation requires it, then review the permission after the trip.

Privacy, Permissions, and Offline Use

A GPX recording can reveal more than a photo. The first and last points may identify a home, hotel, workplace, school, parked vehicle, or private trail access. Timestamps can reveal when the location was empty, while heart-rate and cadence extensions add personal activity data.

Before sharing, trim the first and last section or move the public start to a nearby landmark. Remove private waypoints, inspect names and descriptions, and decide whether timestamps and sensor values belong in the shared copy. gpx.studio exposes sensor-field choices during export; other apps may not.

Local processing and offline maps answer different privacy questions. gpx.studio says file computation happens in the browser, yet map, routing, elevation, and geocoding requests still use external services. Tracklia stores map data in the app but its free version includes ads and Google Play reports identifier sharing. Locus, OsmAnd, and GPX Viewer offer optional accounts or cloud features, but local workflows do not require every online service.

Review Settings > Apps > [App name] > Permissions > Location after installing. Also read the current Google Play data-safety panel, since developers can change disclosures between article updates.

Frequently Asked Questions

Can you edit a GPX file on Android?

Yes. Tracklia, OsmAnd, Locus Map, OpenTrackEditor, and gpx.studio can change at least part of the underlying track geometry and export GPX. Their scope differs: Tracklia covers the broadest direct editing workflow, while GPX Viewer mainly displays data and edits metadata.

What is the difference between a GPX viewer and a GPX editor?

A viewer reads coordinates and draws them on a map. An editor changes coordinates, waypoint fields, track structure, or route structure and saves a new file. Displaying an elevation graph, recording a trip, or following a track does not by itself make an app an editor.

Can Google Maps edit GPX files on Android?

No, the normal Google Maps app is not a GPX editor. Google's own help says custom My Maps can be viewed in Google Maps on Android, while creation and editing happen through My Maps in a web browser. Even there, the workflow edits a Google map layer rather than offering the track-point and GPX-preservation controls of a dedicated editor.

Can I trim a GPX track on Android?

Yes. Tracklia can split and edit tracks, OsmAnd has Trim before this point and Trim after this point, Locus Map can remove sections before, after, or inside a track, and gpx.studio provides crop and split controls.

Can I merge GPX files on Android?

Tracklia, Locus Map, gpx.studio, and OpenTrackEditor can join tracks. When no route planning or map work is needed, the browser-based GPX Merger is a shorter workflow for combining GPX files locally. The related GPX merging guide explains tracks, routes, waypoints, segments, and timestamps.

Can I edit GPX files without an internet connection?

Yes, with limits. Native apps can change a locally stored file without a connection, but the visible map or route calculation may require downloaded offline data. OsmAnd and Locus Map are the stronger offline map choices; Tracklia provides limited offline maps free and unlimited maps in Pro. gpx.studio is not the offline recommendation.

Does editing remove timestamps or elevation data?

It can. Moving, simplifying, merging, or snapping points may recalculate or synthesize values. OpenTrackEditor's roadmap still lists timestamp extraction and elevation graphs as unfinished. gpx.studio documents averaging sensor fields for inserted points, and OsmAnd warns that attaching a track to roads can change elevation, speed, and time-derived statistics.

How do I hide my home location before sharing a GPX file?

Work on a copy, then delete or trim the first and last points until the public track begins and ends at a non-sensitive landmark. Remove home-related waypoints and descriptions. Reopen the exported file in a separate viewer to confirm the private section is gone.

Final Recommendation

Start with Tracklia if the requirement is genuinely editing GPX on Android. It covers the widest useful combination of point repair, waypoint changes, trimming, splitting, joining, reversing, creation, recording, and GPX export, though advanced work requires Pro. Start with GPX Viewer instead when the file only needs opening, elevation or sensor inspection, and offline viewing.

Use OsmAnd instead when offline routing and navigation lead the decision, or Locus Map when careful outdoor track repair will be a recurring task. Keep GPX Viewer installed as an inspector, and always preserve the source file before an editor rebuilds the data behind the line.
