TrekGuard is a free Android hiking and trekking app for offline map packs, mountain weather, GPS/barometer altitude, multi-day trek planning, GPX import, backtrack navigation, Lake Louise AMS self-check, and SOS-style tools. Nepal routes (EBC, Annapurna, Langtang, Manaslu, and more) are built in; you can also plan custom treks worldwide.

Hikers and trekkers who need offline-ready tools on remote trails — especially Nepal teahouse treks and other high-altitude trips. Useful for solo travelers, small groups, and anyone preparing before signal disappears.

No. TrekGuard is a preparation and field companion. Weather on the ground, lodge reports, official rules, licensed guides, and rescue services always come first.

TrekGuard is built for high-altitude safety and weak signal: AMS logging, trek safety weather verdict, barometer altitude, acclimatization checks, SOS flashlight, and Nepal-focused route prep — not social trail feeds. You can import/export GPX and use other apps alongside it.

Yes. Nepal has the deepest templates and offline map regions, but worldwide custom treks, GPX import, altimeter, weather, AMS tools, and recording work on Alps, Rockies, Andes, Patagonia, and other mountain trails.

Get the app on Google Play: search TrekGuard or open the Play Store link from this site. Install before your trek so you can download map packs and GPX while you still have Wi‑Fi.

The Play release we ship is free with no in-app subscription tier. No ad SDK in the default build.

TrekGuard is Android-only today. iOS may be considered later based on demand. This website’s route guides, GPX downloads, and checklists work on any browser.

Use a reasonably recent Android version with Google Play services for installs and updates. For exact minimum SDK, check the Play Store listing on your device.

Many core tools work without mobile data after setup: altitude, compass, backtrack, trek recording, first aid, gear checklists, saved emergency contacts, and imported GPX on downloaded maps. Weather needs a recent online fetch (short cache when offline). Map tiles require downloading offline regions first. SMS and Satellite/Streets map styles need connectivity.

Offline map packs are downloadable map tiles per Nepal region — required to see maps without signal. Elevation cache stores up to 500 ground-height points (fresh ~7 days online, up to ~90 days when offline) to steady altitude readouts. They are not the same thing.

In Kathmandu, Pokhara, or any place with reliable Wi‑Fi — not the night before a pass. Download each offline map region you need, import GPX, pull weather, and save checklists before leaving town.

Yes for tools that do not need live tiles or fresh weather. Airplane mode with GPS enabled is fine for recording, compass, backtrack, and offline maps you already downloaded. Refresh weather and map packs before airplane mode if possible.

Download GPX or KML from a route page, transfer to your phone, and import in TrekGuard’s map. GPX shows the planned corridor — verify the trail locally; landslides and reroutes happen.

They are planning references, not guaranteed safe paths. Trails change with weather, landslides, construction, and local decisions. Cross-check with guides, lodge advice, and current conditions.

When you load a GPX route, the app can warn if you drift roughly 100m+ from the track. It helps catch wrong turns; it does not prove the trail ahead is safe.

Backtrack records your walked path and helps you return along that breadcrumb with compass bearing and distance — useful in fog or dusk. ETA is an estimate from your pace, not rescue timing.

Yes. Finished treks can be exported as GPX for backup or use in other tools (e.g. AllTrails, Komoot). Export while you still have storage and battery.

Seven downloadable regions include Kathmandu Valley, Everest Base Camp, Annapurna Circuit, Annapurna Base Camp, Langtang Valley, Manaslu Circuit, and Upper Mustang. Download only the regions your trek needs.

TrekGuard blends GPS, barometer, and cached map elevation (with manual calibration from trail signs). Accuracy depends on your phone sensors and satellite fix — not survey-grade.

No. The app shows estimated SpO₂ ranges by altitude for education only — not pulse-oximeter readings and not medical advice. Use proper devices and professionals for health decisions.

The AMS checker uses the common Lake Louise self-assessment for logging symptoms over time. It is educational only — not a diagnosis. Worsening symptoms mean stop ascending, rest, descend, or seek medical help.

A field summary from forecast data: storms, wind, cold stress, UV, daylight, pressure trends, and altitude context. Use it with what you see in the sky and local reports — not instead of them.

You need connectivity to fetch fresh forecasts. A brief cached view may show when offline, but do not rely on stale weather deep in the mountains.

Yes. Multi-day plans can flag large elevation jumps and suggest rest days. You still make the final call with your body and guides.

No pre-loaded rescue directory. You add personal contacts and local service entries (police, ambulance, rescue, hospital) or import from your phone. Set these up before the trail.

When your phone can send SMS, TrekGuard can share GPS coordinates in a text message. It is not satellite SOS (InReach, PLB). No signal means no SMS.

It flashes a Morse SOS pattern on your phone torch for visibility. Battery, weather, and distance affect how well others see it — carry a real whistle and proper emergency gear too.

Yes — offline reference for common trekking emergencies (AMS, cold injury, wounds, etc.). It supports learning; it does not replace training or evacuation decisions.

Live GPS recording of route, distance, pace, elevation gain/loss, and max speed with a shareable summary. Background GPS drains battery — cold weather makes it worse. Pause when resting.

Saved points (camp, water, junction, teahouse, viewpoint, danger, etc.) with compass bearing to navigate. Useful for marking spots you want to find again.

Interactive packing lists (clothing, footwear, camping, electronics, safety, hydration, navigation, personal). Progress saves on your device. Completing it can unlock a preparation badge in the app.

Badges celebrate milestones (trek count, altitude, hydration, checklist prep). Trek Photo stamps altitude and GPS on images; place names need recent geocoding when online.

Yes — daily water goals with altitude-aware reminders. Hydration helps recovery; it does not replace descending if AMS symptoms appear.

Templates and guides cover popular areas: Everest (EBC), Annapurna Circuit & ABC, Langtang, Manaslu, Mardi Himal, Mustang, Dolpo, Kanchenjunga, Makalu, and more. Browse /routes for GPX, itineraries, and checklists.

Yes. Route guides, blog articles, safety tips, and printable checklists work in your browser. The app adds offline maps, live GPS, weather, recording, and on-trail tools.

Permit and budget notes are planning aids — rules and fees change. Confirm with official sources, trekking agencies, or embassies before you travel.

Route and blog content is published on trekguard.app (and Sanity CMS). The app bundles templates and can sync trek JSON from the project when configured — treat both as prep tools you verify locally.

No account required. Core trek data stays on your device. We do not sell your data. Optional analytics may run when configured; it should not market your live GPS track as a feature.

GPS is used for altitude, maps, trek recording, backtrack, waypoints, weather for your position, and SMS coordinate sharing. Denying location limits those features.

Update TrekGuard and Android, confirm storage permission, re-download the offline map region on Wi‑Fi, restart the app, and re-import GPX. Email support@trekguard.app with device model, Android version, trek name, and screenshots.
