Oscar°
Accurate forecasts and measurements from leading weather services, right in your pocket. Because your weather report shouldn’t be a privilege.
Free and without ads.
Forecast
Forecasts straight from
the weather services.
The data comes from national weather services like the DWD, Météo-France and NOAA. Oscar brings it to your phone, together with live radar and readings from weather stations near you.
Hour by hour for the next two days, and day by day for twelve. Tap any hour to see it in detail: temperature, rain, wind, humidity, pressure, clouds, even soil moisture. And if you have a favourite model, you can pick it in the settings.
Ensemble
How sure is
the forecast?
For an ensemble, the same weather model runs dozens of times, each with slightly different starting values. If almost all runs land in the same place, you can rely on the forecast. If they spread apart, the weather is still up in the air.
Radar
Know when the
rain gets here.
Live radar, plus a forecast of where the rain moves over the next two hours. If rain is heading your way, Oscar lets you know before it starts. While it rains, your Lock Screen shows how heavy it is and when it should stop.
Radar, rain alerts and the Lock Screen view are available in most of Europe, the US, Taiwan and Brazil.
Maps
Rain, temperature,
wind, pressure.
Every layer plays forward hour by hour. Central Europe runs on DWD’s high-resolution ICON-D2, the rest of the world on ECMWF.
Radar from six national networks, plus a two-hour nowcast. Storm cells show where they’re heading.
Warnings
Official weather
warnings.
When a weather service issues a warning for where you are, Oscar shows it to you exactly as it was issued. As a notification too, if you like.
Warnings for Europe, the US, Canada and Taiwan. Notifications everywhere except Canada.
And all the little things.
How warm is it, really?
Each stripe is today’s date in one year since 1940. You see at a glance how today compares to what used to be normal where you live.

Privacy
Not interested
in your data.
No ads, no tracking, no account. Here’s where your data goes, and why:
- Open-Meteo gets your location, rounded to about 100 m, and what you type into the place search. It sends back the forecast.
- Oscar’s server gets the same rounded location for radar, stations and warnings. If you turn on notifications, it also keeps a push token and your rounded location until you turn them off, so it knows where to watch for rain.
- Apple turns your location into a place name, delivers notifications and handles tips.
- Sentry receives crash and performance reports, stored in the EU, so bugs get fixed. A report can include a screenshot of the moment something went wrong. You can turn them off in the settings.
- OpenFreeMap delivers the map tiles.
None of it is sold or used for ads. Your usage statistics stay on your phone and in your own iCloud. All details are in the privacy policy.
Made by one person.
Hi, I’m Philipp. I build Oscar on my own, as a hobby in my spare time, and pay all the costs out of my own pocket. If you’d like to chip in, there’s a tip jar in the settings. As a thank-you, you get a few extra app icons and stickers.
