Just an example weather app for the pebble watch. To build you will need the Pebble SDK 4.1.0+ and either the pebble watch or the qemu pebble watch emulator. Then from the root directory you would run:
$ pebble build
$ pebble install
or for emulation without a phone:
$ pebble build
$ pebble install --emulator diorite
Note this app is written for the diorite target (Pebble 2), older Pebble support like original Pebble or Pebble Time is not supported.
