Sleep Apps

• None of these appear to have measure of actual sleep time like FitBit, where FitBit does not count the time awake during the night (1/2-1 hr typical) in the total sleep time. The desirable feature is to set the alarm after an actual sleep time is achieved - AND during a light sleep phase, not deep sleep.
