One conclusion, every source visible
Your conclusion is the bold line, with a shaded range around it. Every source's own line sits underneath it, so when the sources disagree you see it, instead of a single number that hides it. Temperature, rain, wind and more, by the hour and by the day.
A track record, earned on your phone
The app saves the forecasts it fetches and later compares them with real readings near you: a weather station for temperature and wind, and a rain gauge for rain where one reports (England at first). A source that keeps being right counts for more. Until there is enough history, the app says it is still learning, and it never shows a score it has not earned.
Rain, with its other half
30 percent rain also means 70 percent dry, and the app shows both. Chances are put into plain words - unlikely, possible, probably, likely - and the same words are used in the app, the widgets and the alerts.
See what changed
A change log tells you when the forecast moved, for example rain arriving earlier than it did this morning, so you know whether to trust the new answer.
Ranges, not false certainty
Every number comes with the range it could land in. Where the app has not yet checked that range against real outcomes, it says so rather than calling it a confidence interval.
Radar where it is licensed
Rain radar from national weather services where they cover your area: the United States, Germany and Canada. Elsewhere you get a rain map from forecast models, clearly labelled as a model and not radar.
Widgets and rain alerts
Home Screen and Lock Screen widgets. Rain alerts are optional and off until you switch them on, and they are scheduled on your phone itself.
Plain words, on your device
On iPhones that support Apple Intelligence, the on-device model can put the conclusion into friendlier words. It only rephrases: the numbers, ranges and confidence always come from the app's own calculation.
Made for every screen
iPhone and iPad, light and dark, two looks, large text and VoiceOver. English, Simplified Chinese and Brazilian Portuguese.
No ads, no tracking, no account
Nothing to sign in to, no advertising and no analytics. We run no server that receives your data, and your track record is built and kept on your device.
Honest limits
A brand new place has no track record yet, and a short history can only say so much. The app tells you when it is in that position. Forecasts are forecasts: the range is there because they can be wrong.
