topo^alpin

topo^alpin is your planning tool for alpine mountain tours. Draw your route directly on the map or upload a GPX file, analyse slope angles and elevation profiles, and navigate to the summit via GPS – all in one app.

Interactive maps:
- slopemap HD: custom base map and slope angle maps at 5 m resolution for the entire Alps
- Official topographic maps from swisstopo (CH), BEV (AT), LDBV (BY) and IGN (FR)
- Aerial imagery from the official sources of the Alpine countries, one tap to switch
- 3D relief: tilt the map onto the elevation model and rotate it – look at a south face from the south
- Avalanche terrain classification ATES (AutoATES v2) for the Alps and SLF CAT/ATH
- Ski touring, snowshoe and hiking trails
- Wildlife and herd protection zones
- Offline maps: download map tiles in advance for areas without reception

Route planning:
- Draw your route on the map with automatic DEM elevation data
- Upload GPX files and analyse the elevation profile with slope angles
- Open up the elevation profile with your finger and study key sections in detail
- Export drawn routes as GPX files
- Share a tour as a PDF: map, tour figures and elevation profile on one sheet – to pass on or print out
- GPS navigation to the summit or along your route
- Slope meter with live device sensor
- Compass rose, distance, elevation delta and progress indicator
- Dynamic Island and Lock Screen: remaining distance and elevation at a glance

Mountain weather:
- 6 weather models (ICON EU, ICON D2, AROME, ECMWF, GFS, AIFS) as a weighted ensemble
- 2-day weather summary with avalanche danger level at a glance
- 10-day overview and 48-hour detail view with colour weather icons
- Elevation grid: rain or snow per elevation band, with the snow line as a line
- Thunderstorm risk, summit wind at various elevation levels
- Freezing level and cloud base
- Fresh snow (24h/72h/7d) from the nearest station – automatically during snow season
- Sunrise, sunset and daylight hours – elevation-corrected
- Weather warnings from MeteoAlarm for the Alpine region
- Real-time mountain weather stations from CH, AT, DE, IT, FR and SI

Emergency location:
- Your own position in decimal degrees, degrees/minutes and UTM – to read out to a dispatcher
- Elevation, GPS accuracy and the age of the fix, offline too
- Nearest named terrain feature where there is signal, e.g. "600 m north-east of Schwarz Berg"
- Emergency numbers by area: 140 (AT), 1414 Rega (CH), 144 (Valais), 118 (Veneto), 112
- Copy the coordinates or share them as a prefilled text message
- Dialling only after a five-second hold, so nothing is triggered by accident
- Not an emergency service: topo^alpin dials through the phone app and transmits no data to a control room itself

Tour-Check:
- Risk assessment of your GPX tour with key-section markers directly in the elevation profile
- ATES avalanche terrain classification and terrain risk overlay along the whole tour
- Toggle in the elevation profile between Tour-Check and terrain risk
- Avalanche danger level fallback in Settings if no current bulletin is available

On iPad:
- The same app with more map: the tabs at the bottom, the map across the full screen
- Portrait and landscape, and in a window beside another app
- No dialling: an iPad cannot place a call, not even with a cellular SIM. The emergency location screen still shows coordinates, altitude and the report text – to pass on by phone or radio

topo^alpin is a self-responsibility tool. It does not replace alpine experience or careful tour planning.
