Additional Details

Apps entered to the Pebble App Challenge must use Pebble SDK 2.0 and be submitted on Pebble appstore, available through both Pebble iOS app on Apple iTunes Appstore and Pebble Android app on Google Play.  The challenge is open to all apps available in the Pebble appstore, meaning existing apps may compete.  Developers may also enter multiple apps.  Paid apps may enter the challenge.  However, developers should consider offering the app for free to increase downloads and votes necessary to win.
