Great Use of crowd source data

This is an excellent app for gathering crowd source data. The interface is clean and relevant. I think the little sayings after the rain alerts are pretty cute. Who says developers don't have a sense of humor?

I use this app every day. Fantastic way of using crowd-based data to improve weather forecast accuracy. But recent versions have had issue with the location and PSI updates. It tells me I'm in AMK even when I'm at Tuas or Orchard! And PSI has been stuck at 54 at 12pm for weeks. Will bring back to 5* after they fix this.

I'm very satisfied with the app! I find the crowd cast interesting and creative! Love it! Thanks for making this app!
