Swiss Pro Map is a map app for hiking, mountaineering, cycling and aviation in Switzerland and the Alpine region, made by Garzotto GmbH. It combines maps and aerial images from swisstopo, OpenStreetMap, OpenTopoMap and MapTiler with route planning, elevation profiles, search by place names and coordinates, public transport timetables, points of interest and ten configurable profiles. After the data has been downloaded, all functions except weather data work offline, according to the vendor. The app runs on Android, iOS and Macs with Apple silicon.
Garzotto GmbH is based in Winterthur, Switzerland, and no foreign parent is stated. The vendor says that position, tracks and routes remain private on the device, and that no registration is required. The app uses map data from several providers and some online content, but the vendor does not state where its servers are located, so ask if this matters to you. Switzerland is an EFTA country with an EU adequacy decision.
