It displays its data quickly, but it doesn't find the city where I live (small European city). I can have a bigger city, but I prefer the weather app with my own city displayed, It's more accurate.

The good: All free and doesn't have an over priced "pro" version to unlock basic features.
The bad: Could be a bit more intuitive, for example differentiating between "default" and "favourite".
Overall: Well worth a try.
