SleepTracker
Windows PCMac OS


Silent alarm clock and sleep sensor for iPhone/iPad. Designed with Harvard sleep expert and pro sports sleep coach. LARK wakes you silently and gently- you’ll even snooze less. The LARK wristband (lovingly known as wrist pajamas) uses an actigraphy microsensor to detect your unique sleeping patterns. No syncing, it automatically shows up on your phone.
SleepTracker’s SmartStart Technology monitors your sleep stages throughout the night and then uses that data to determine the exact moment when you should be awoken helping you feel refreshed and energetic. SLEEPTRACKER also comes with the most comprehensive sleep software available allowing you to see how you slept, ways to improve your sleep, and your overall sleep score.

I got one for Christmas - it is very awkward. After less than a week, the USB contacts literally fell out of the watch. So much for that. I'll give them the benefit of the doubt and exchange it (though - ripoff alert - they want $10 for that. Better to return it and purchase a new one without paying $10.
Another large drawback: no snooze button. So, if your alarm goes off and you fall back asleep, the watch doesn't wake you again. Considering it supposedly knows when you sleep, that seems pre...
