I just published my first Pebble app. It’s a simple speed dialer, the watch initiates a call on the phone. The contacts are preselected via the phone companion app.
Give it a try. Search for “Speed dial” on your Pebble-connected Android device, or follow this link: http://apps.getpebble.com/en_US/application/5626ae103b5b31492e00008a
