I've tried it for a week or so; didn't work for me. The accelerometer did pick up on my movements, though. Also, I think putting my iPhone at the corner of my bed is a little risky. When sleepily reaching for your phone in the corner of the bed it's easy to drop it, scratch it against the wall, etc. Even when you're generally a careful person; it's going to wake you up 300 days a year, and it has to go wrong only once. I'm hoping sleepmate does a better job.
