Cool, i will take a look at your source and probably do some pull requests too

disclaimer: i'm new to pebble and never used pebble with android or iphone, except using a friends android to update my firmware and install some apps

As far as i understand the pebble sdk, until pebble sdk 2 you needed a companion app on your phone to communicate with the outside world and the pebble.

With sdk2 they added a JS api Which runs inside the offical pebble phone app and allows you to write your "companion" apps in js, with simple settings and outside world communication

Maybe at some point we could emulate this JS engine to support some of the watchapps/faces nativ
