This is really useless!!

If I turn on the smart measurement,even Im not on bed, beddit is always running on my iPhone. It should measure sleep only when Im on the bed!! What is the purpose of GPS tracking? If Im out home, it just drain battery. If Im home it just drain my phone battery. I dont want to use gps but need activation only when Im on the bed!!
If this item cannot activated by bodyweight pressure, it is just same as stopwatch. Really dont recommend. This is scamm!
