Meteosuisse is awful, and they retroactively correct it to make it look like the forecasts were right!Highly recommend "search.ch" for Swiss weather.
The one I used the most was Wetter Alarm which combined a few sources and gives webcams for peaks and resorts.
But now iOS16 gives us nice alert popups - and it seems accurate for my area - and I'm a sucker for the animations - I'm going with that.
Will have a look at search.ch tho, cheers!
