I’ve been hunting for a radar app as good as Dark Sky ever since it was discontinued, but not found one so far. Currently I’m using Ventusky (on Apple) because it provides a lot more detail than rain radar (wind gusts, air pressure etc).

It’s great. Has overlays for wind, radar precipitation, satellite cloud cover, you name it. Plus you can compare the forecasts from a lot of the big name forecasting models.

I use an app called WeatherRadar - https://apps.apple.com/gb/app/weather-radar-storm-alerts/id545993260

It shows cloud cover as well as rainfall, and also has a few other views I don’t use. But what I really like is the iOS home screen widget, which shows me my local weather even when I’m not actively looking at it.

I use hyperlocal weather app. Radar and longer forest (like it’s useful in uk lol), better/clearer interface imo

Netweather is probably one of the bestw rather sources for the UK, second to the metoffice.
