There are sleepanalyzers for several OS. As far as I understand, I'm not an expert, an accelerometer is needed to analyze the depth of sleep and make a graph of it. (That's what these analyzers do)
Is it theoretically possible to build such an app. for the N900? .

Thanx for answering,

It's very possible. The API for using the accelerometer is documented so it's a SMOP (Simple Matter of Programming).

Of course it's possible. But this is the problem with iPhone apps--the general worthlessness of what appears to make the phone so versatile. Go get a real sleep study done medically where thery measure your eeg, breathing, heartrate, and O2 sats.

Accelerometer, microphone or camera; all those can do it with suitable algorithm and program. Your big muscles are either totally relaxed, or then not and moving.

Would be something special to have all those sensors in N900 program and do correlation based algorithm on those optionally. Something other devices wouldn't have.

I know that such an app. is not very scientific, but it can more or less objectivy the feeling of having slept well, or having the feeling to get up 'broken'in the morning.

i would also like to see an app like this and like happywakeup i used to have it on my N95 and it worked well.

I know there is already one application in n900. The application name is "sleeppy". I've used several times, and it is a simple application. The app is checking the sleep patten and writes a log and you can set up alarm.

Is it already in the N900? Where can i find it?

I found it on the web. It exists in Russian language only.
Waiting for a translated app.
