The app interface is very simple... It lets you pair the phone with the Pebble smart watch, and download the companion app that has to be running on the watch.
The watch app is even simpler, offering three choices: Alarm, flashlight and vibrate. If you choose alarm, your phone makes a chiming noise, even if its set to silent; if you choose vibrate, the phone will buzz once. The flashlight option didnt work for me... I assume its supposed to trigger the camera flash, but nothing happened when I chose that one.
I ended up deleting the app because, when I returned to the home screen, entered my phone settings, and scrolled down to the settings for this app, I found a long list of poorly labeled options, including some unlabeled options, that may or may not do anything at all. Thats probably poor design, and not malicious intent, but I cant see what all of those settings control, and I figured Id play it safe.
If all of the features worked, and the settings issue were fixed, I might suggest this app for fellow Pebble owners.
