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
• 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

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