I use the Weather Forecast app from F-Droid, which uses yr.no data.
Not because that’s always the best, but because that data maybe literally saved my life once.

(I was hiking in the Alps with friends and yr.no showed a snow storm coming right where we were headed that day. Everyone else including a local guide said it’s OK since their weather report didn’t show it, and they went on to climb over the next ridge. Me and my friends were the only ones who descended into the valley instead. Later that day, we noticed a helicopter rescue was started on that ridge and the next day we read that one of the hikers had died that day)
