VPNs and other tools worth installing before you go, curated for travelers visiting Switzerland.
MeteoSwiss is the broadly useful official safety app, especially for mountain, lake and winter itineraries. It provides local forecasts, precipitation and wind animations, measurements and federal natural-hazard warnings. Its hazard map can display avalanche warnings, but travelers entering unsecured winter terrain should use the detailed SLF avalanche bulletin in White Risk and must have the training and equipment to interpret it. White Risk is not needed for an ordinary city visit or marked open piste. The Rega app is worthwhile for hiking and remote outdoor activities because an emergency call can transmit the phone's location to Swiss Air-Rescue; set it up and test it before the trip. Rega patronage is a donation arrangement, not insurance, and does not guarantee that every rescue cost will be waived, so buy activity-appropriate travel and rescue cover. Alertswiss is the optional federal and cantonal civil-protection channel for official alerts such as drinking-water contamination, power failures and forest fires. It needs data for new notifications, and an alert may not be available in every supported language. Save emergency numbers independently: 112 general, 117 police, 118 fire, 144 ambulance and 1414 Rega within Switzerland. Apps, location sharing and live maps can all fail without signal or power. Tell someone the route, carry power and offline details, and call rather than opening an app during immediate danger.
