@Korina Have not yet found any features with Premium that are useful. I will keep looking. Meanwhile, I cancelled Premium, in case I forget in a year and pay another $20 that might be a complete waste for me. I will also look for alternative weather apps. I thought the radar feature would extend one hour instead of remain the same. Disappointed. Maybe, I will find some use for Premium features. Not so far.
edit: hourly forecast is worthless because I don't live close to one of the forecast cities. I'm just going to accept that I paid $20 for nothing and move on. I have enjoyed using Windy in the past so I will just consider this $20 a donation. Premium isn't worth anything for me.
