TrekGuard: Nepal Trekking Map

TrekGuard is an offline trekking app built for high altitude. Know your real altitude and how much you can trust it, check for altitude sickness (AMS), and get a clear trek-safety verdict for mountain weather — even with no signal.

Made for trekking in Nepal — Everest Base Camp (EBC), Annapurna Circuit, Annapurna Base Camp (ABC), Langtang, Manaslu, Mardi Himal — and works on mountain trails worldwide.

Free. No subscription. No account.

ALTITUDE & AMS SAFETY
• GPS + barometer + terrain altitude with a confidence readout, so a bad reading never looks certain
• Real-time elevation gain, loss, and ascent rate
• Acclimatization and altitude-gain checks for multi-day itineraries
• Voice altitude alerts during active treks
• Educational AMS self-check using the Lake Louise score, with symptom history
• Offline altitude calibration from trail signs

OFFLINE MAPS & GPS NAVIGATION
• Download offline maps: preset Nepal regions or any area you frame
• OpenStreetMap-based trails, footpaths, and place names in Outdoor, Bright, and Light styles
• Live route tracking and backtrack to find your way back
• Drift alerts to help avoid wrong turns
• GPX import/export and waypoints

MOUNTAIN WEATHER & TREK VERDICT
• Hourly and 7-day mountain forecast
• Trek Safety Verdict for storms, snow, wind, cold, UV, and daylight
• Freezing level, precipitation, and pressure trends
• Shows when the forecast is stale instead of pretending it is fresh

EMERGENCY TOOLS
• Share your GPS coordinates by SMS: TrekGuard prepares the message, you press send
• Offline outbox keeps undelivered emergency texts until signal returns
• SOS flashlight, emergency whistle, and quick-dial contacts
• Offline first aid guide

TREK RECORDING & HISTORY
• Record routes with distance, pace, elevation, and max speed
• Replay a finished trek on the map: scrub altitude, pace, and position
• Trek history with stop summaries and elevation profiles
• Shareable activity cards

PLAN & PACK
• Multi-day itineraries with day-by-day altitude profiles
• Gear checklist with season and altitude filters and a live pack-weight total
• Build custom routes and export GPX

WORKS OFFLINE
Maps, GPS navigation, altimeter, compass, backtrack, trek recording, checklists, and first aid all work without mobile data. Weather updates, SMS sending, and map downloads need a connection.

• Metric or imperial units (emergency coordinates and GPX exports stay metric)
• Your trek data stays on your device

BUILT FOR
• Teahouse treks in Nepal: EBC, Annapurna, Langtang, Manaslu, Dolpo
• Solo trekkers and small groups without a guide
• High-altitude hiking, backpacking, and trekking peaks worldwide

TrekGuard supports your judgment; it does not replace it. Conditions on the ground, local advice, your guide, official rules, and rescue services come first. AMS tools are educational and are not a medical diagnosis. If symptoms get worse, descend.
