Hello! I'm looking for a foss weather app for android, so I went ahead to f-droid and tried a bunch of them, but didn't find any that fully satisfies me: I want to be able to see the hourly forecast of any day of the week, not just the "global" forecast, and I want the weather service used not to require a credit card (openweathermap.org for example requires the credit card to get an API key). Geometric Weather is the one that I'm currently using, with open-meteo as provider, but sadly it displays hourly forecasts only for the current day, but not for other days.
The Breezy Weather (fdroid link) is a fork and continuation of GeometricWeather. As I can see, there are hourly forecasts for the next days, just scroll horizontally (AccuWeather and Open-Meteo providers, tho, I haven't checked others).
I just wish it had a precipitation radar. I'm pretty sure the data is available because I've seen another FOSS app that had it, but I can't remember which now.
