Looking for feedback on rainfall app I'm working on

Hey all. I'm a local rider (got into mountain biking a year ago and loving it). I've been working on an ios app that tracks rainfall by location. On rainy weeks like this week, I use it for potentially finding rideable trails in the area. Though this week is looking rough...

Would love some feedback if anyone wants to try it out (free to save 2 locations, unlimited map lookups). Also curious about:

• What weather info matters most to you when deciding to ride?
• How far out does a forecast need to be useful for planning rides?
