Show HN: My first app – The minimalist distance-based transit alarm

Hi all!

I'm a 17-year old self-taught developer just starting to tap into the mobile world! :3

This summer, I've worked on a minimalist distance-based alarm clock app that wakes you up before you miss your stop!

Check it out here! http://www.windowsphone.com/en-us/store/app/commuter-buddy/cb9b5107-41e0-4d2b-b0d6-110fe555fc3b

Feedback and comments are welcome, thanks :)
