Sleep Phase wakeup clock now available on the App Store
Sleep Phase wakeup clock, my second iPhone app is now available on the App Store. It’s a alarm clock, which monitors your sleep rythm through the iPhone’s microphone or accelerometer and wakes you up in a light sleep phase, which means you’ll feel energized and refreshed every morning.
Originally I had this idea more than a year ago, but did not start to experiment with some code untill last summer. I was about to wrap everything up this christmas, when I stumbled upon Sleep cycle alarm clock, which was released about a month ago. They’ve sold over 100.000 copies in the first month. Lazy me, could have beat them to the store had I tried a bit harder. Well, life sucks.
Anyways, I do appreciate what I learned from this “project”. It all came together much easier than Web Feeds, the first iPhone app I created one and a half years ago. Go ahead, give it a go, it’s not that expensive 
Update: I pulled the app from the store. I realized that I need to figure out a better, more descriptive name than “Good Night”. Unfortunately the app name cannot be changed once it’s submitted.
Update 2: It’s available once more under the Sleep Phase wakeup clock name.

The app seems to be back named as “Sleep Phase”? Just bought it and has one question: it says I can lock my phone, but once it said I must NOT lock my phone. The latter occurred after I had locked the phone and removed it from charger while the app was running.
So can I lock the phone or not?
You can lock your phone if:
1) You are using microphone monitoring
2) You keep your phone charging
If you lock your phone and have don’t have it on a charger, the app will be put to sleep by the OS.
Hi Tuomas, I was just wondering if you plan to include some kind of graphing capability in a future update, or another method to analyse the data your app collects overnight.
I bought and use the competing Sleep Cycle app, but in truth I wanted to buy yours more. The only reason I didn’t is because I needed the reassurance from the graphs that it was actually working properly.
If you included those, I would happily switch to your app, as I prefer the idea of use the mic so I can leave it in my bedside table.
Hi Andy, yeah, graphs are planned, but I don’t now when I have the time to implement those.
