As anyone who has slept with me will confirm, I tend to toss and turn all night. Thanks to a fun Android app, even the distressing number of you who have little desire to share a bed with me can see just how bad it is:



I only used it for the first time last night, but I'm curious to see what patterns emerge over time. I'm looking forward to playing with the optimally timed alarm feature -- I've wanted to try that for years, but custom hardware is expensive. Yet another reason that having a general-purpose computing platform with an accelerometer is awesome!

Thanks for the tip. I got the app and tried it. It's really really well done!

I think there is a fundamental problem with setting the threshold... the phone doesn't know how close it is to your body. In my case, it only detected actual awakenings (two big spikes in the morning), with much smaller bumps at ~6:15am and ~3:45am. So it's unclear from your graph how many times the threshold was crossed (and how reasonable that threshold is).
