Sleep Cycle (iPhone App Review)

April 9, 2010

I was excited when WakeMate was first announced. I could finally have an app for analyzing my sleep patterns and help me get a better night’s sleep. But, due to a horrible launch, I still haven’t received my WakeMate (it was supposed to ship in January).

To fill the void, I found Sleep Cycle on the app store for only $0.99. It doesn’t really help me get a better night’s sleep, but it shows me what all goes on during the night. Sleep Cycle uses the iPhone’s accelerometer to measure your movement during the night and will wake you up in your lightest sleep phase.

The app is extremely simple and well thought out. You can view instructions that are step by step and include photos, test the app to see if it picks up movement, set the alarm, and view your sleep graphs from previous nights.

To use Sleep Cycle, first set the alarm:

Next, it will remind you on how to use Sleep Cycle. I do wish there was a way to turn this off.

Once you hit ‘OK,’ you’re taken to this screen. Just slip it under your bottom sheet face-down, and you’re good to go.

After your night’s sleep, Sleep Cycle will wake you with music you’ve set before hand. The music gently fades in, then gets extremely loud and the phone starts to vibrate if you let it set too long. If you’ll notice, it didn’t wake me up at 6am, but 5:44am, because that was when I was sleeping the lightest, according to Sleep Cycle.

After you’re awake, you can view your sleep graph and e-mail it or post to FaceBook.

I do remember rolling over to look at the clock around 12:30am, so at least I know it’s accurate.

I would imagine this app doesn’t work well with two people in the same bed (or more for that matter), or on those fancy beds that don’t register vibrations or movement.

If you’re looking for an app that lets you know why you feel so tired in the mornings, Sleep Cycle will help you out a little. I’ve figured out that if I go to bed at 10pm or 11pm, I usually wake up feeling good. If I go to bed around 10:30pm or after 11pm, I don’t feel so great in the mornings.

It’s only $0.99, and it helps fill the gap until WakeMate arrives sometime later this year.
