The $100 Pebble Core is advertised at the link as an Android device.

It's also much bulkier than the watch and has no screen. It has a lot less to deal with and they can carefully control what apps it's running since the user has no input.

The Core is also advertised as lasting through "5 days of 45 minute workouts" - I imagine that 3:45 battery life isn't too tough to achieve

Yeah, their lighter platform seems to be a win for battery. But their cheapest product is going to be an Android widget, presumably because that is an easy path to a broader range of features.
