Mostly: Weather & Rain Radar
Alpine weather, alerts, widget
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
New: rain radar for the US too, hurricanes with their forecast cone and tornado warning areas on the map – and official warnings in your language.
Mostly shows the weather for your place – with rain radar, official warnings and mountain weather. And it tells you honestly how sure the forecast is.
WHAT YOU GET
• Current conditions, the next 48 hours and 10 days
• Rain radar for Europe and the US with place names, plus hurricanes and tornado warning areas – or through Windy
• Official severe weather warnings for Europe and the US: GeoSphere Austria, Deutscher Wetterdienst, the national services via MeteoAlarm and the US National Weather Service, as a notification if you want
• Mountain weather by elevation: temperature, wind and gusts from the valley to the summit, plus thunderstorm risk, snow line, foehn and summit stations
• A second source to compare against, so you can see where they disagree
• A home screen widget
• German, English, Spanish, French and Italian
HOW SURE IS THE FORECAST?
Most weather apps give you a number. Mostly adds a blue band: narrow means a clear situation, wide means several outcomes are still open. The curve is the median of the ICON ensemble runs; the band spans the 10th to the 90th percentile. That is the spread of the model runs, not a guaranteed probability of being right – and the app says so too.
NO ACCOUNT
Mostly keeps no accounts and never asks for your name. For warnings your place is stored rounded to about 100 metres — enough for a warning region, too coarse for an address. Switch them off and it is deleted.
MOSTLY PRO
Mostly Pro removes the advertising – as a monthly or a yearly subscription. The store names the price for your country before you buy. The subscription renews automatically until you cancel it in the App Store or on Google Play.

Mostly 1.10.0
• Rain radar now covers the US too, from the weather services' own radar networks; where no radar measures, the map is hatched
• Hurricanes with their forecast cone and tornado warning areas on the map
• Official warnings in your language, machine-translated and marked as such
• "How sure?" now sits above the certainty word
• The tab is now called Radar
