I tried Geometric Weather for a while. I appreciated that it actually had everything I’m looking for in a weather app: up-to-date data, a widget and severe weather alerts in notifications, though I moved on from it because those notifications would keep popping up every time the app refreshed the data. That issue was being worked on when the main dev vanished. I’m sure this fork will take care of it, and I’ll be watching for when it drops on F-Droid.
