Hi All

This is a beta application which monitors your sleep cycle, and sets a gently increasing alarm to go off at up to 30 minutes before your set alarm time (during your lightest sleep phase so that it's easier to wake up fresh). If you are interested in testing it, please download and install the CAB here:

CAB link removed because its a very old version, a much improved version will be released on this thread very soon.

You can click Menu>Export Chart as a JPG image, and Menu>Export CSV to see the raw data. Please include the chart and raw data if you send me a bug report etc.

Method of calculating lightest sleep phase: alarm can go off up to 30 minutes earlier than the set alarm time if you become more alert than you were at the lightest phase of the previous sleep cycle. If alarm does not go off early, as a failsafe it will always go off at the set time. The alarm does not affect any other alarms you may have set, so I would recommend setting some other alarm too as a failsafe.

Developers: I would appreciate it if I could find a keen .NET Compact Framework developer out there to open-source and maintain this project because I don't have any more time to work on this.


All Windows Mobile 5, 6, 6.5 devices which have a gsensor/accelerometer. All resolutions supported. Tested on Touch HD.

Can you make the Alarm Up-Down button larger. It is to small for my big fingers.

I tried this latest release on my Touch HD last night. I had two bars of battery left and it had run out by the time I woke up in the morning so the alarm didn't go off.

Hi Ashfaq,

great work in this short time. Are you going to release the project as open source and e.g. host it on codeplex?
Probably you should reconsider the name of the project or talk to the people from for not running into trouble...
