Please fix the 'must set alarm' thing! I got one of these for my wife for Christmas. For some reason I assumed it had a vibration alarm, but that's no big deal since she'll mainly be interested in the analytics. But we definitely can't have any chance of an audio alarm going off around her wake time.
We do support a vibration alarm on the phone and if you only want to use the analytics you can just set an alarm for the middle of the day as a fix until we release the analytics only fix.
