I like geometric weather quite a bit. Their widgets look nice too

You can ask this and probably get a different answer for each comment! It really depends on what you want from it and what data sources work best where you live. I’ll mention a few:

• Forecaster is super simple, displaying the forecast for each day as a bar. Yellow represents clear weather, grey represents cloud, and so on. I quite like it, although you can only see weather, temperature and wind, and it uses Apple Weather with no option to use something else.
• Clyma is by far my favourite. It looks the best and offers the most data (like wind gust and feels like temperature) and displays it in a graph. Although it’s very unreliable, and sometimes stops refreshing entirely. I have to clear the app’s data, then enable the location permission before I launch it again to get it working. So I can’t rely on it that much.
• Overdrop is a little bit like Clyma but it hasn’t made it onto my new phone.
• Today should get a mention. I don’t use it much but it’s got by far the biggest array of sources to choose from, and you get data on air quality that you don’t see much elsewhere.
• Meteogram is great if you really like customising and getting into the data itself. You can completely change how the graph looks and what data is included. I bought it on sale a while back and still have access to the old “Credits” system, so I can’t speak for how the new subscription model works but there’s still a free tier.
• Forecastie and OpenWeather are nice ways to access OpenWeatherMap data if that’s what you prefer.
• The Met Office app is a nice way to get notified of warnings if you live in the UK.
• And RainViewer is a very nice radar app, but the imagery doesn’t seem to update very often here (even with Premium, which is meant to give you a 5-minute resolution. Other apps have this imagery, so I don’t quite know why they don’t because they definitely used to)

Hopefully some of that helped someone!

Im using Forcastie, it’s on Fdroid

Nope weawow is the best. It’s one of the few non-FOSS apps I use. No tracking that I’m aware of.

I use an older version that still had Dark Sky, and it has the most accurate weather prediction where I live (middle Europe).

a ton of great options in the thread, but also take a look at Dina. It leverages AI to recommend outfits lol.

also looks pretty nice

I use YR Norwegian Meteorological Institute’s weather reports.

and have the widget show Precipitation for my chosen city. (work related requirements)

now this might not be perfect for others, but as I live in Finland the weather reports are quite exact and correct.

I’m really liking OSS Weather, it’s OSM weather component.

I really like Weather Today since it has Apple’s weatherkit data, which is basically Dark Sky. It also has a really nice radar view and a per minute rain forecast. There is also Shadow Weather which has this support, but I find the UI to be less appealing.
