Interesting use of the technology! Might not work as well for those who share a bed with another person, though...

If the mattress is shared by two (or hey, let's not be conservative - multiple ) persons, then the measurements would be confusing. A better approach might then be to strap the device (assuming it's a phone, not a tablet ) to ones own body.
