Cool app, cool idea. But I had to knock off a star for a weird log-in quirk. The desktop version offers the ability to log-in via Facebook, but the mobile app doesn't. Because I registered via Facebook from my laptop, I am essentially locked out of my account on mobile because there's no Facebook log-in option there. Fix that bug and you're gold.
Im sure its good... But I don't have a numerical zipcode. I have a postal code (Canadian). Can't use app because the account you need to create will only accept zip codes.
Nice App Nice App
