I developed very simple application - stop-watch with sound. The application provides sound every second. Version 2.10 includes countdown timer with alarm. The application is useful for creating nervous environment for some tasks with time limit. I think it should be very useful for exams - teachers, trainers, etc.
The Ticking Timer remembers the last settings of ticking and alarm sounds as well as last countdown timer/stop-watch mode found under Options menu.
For sound selections put *.wav files into folders other than system. Of course, for ticking sounds use *.wav files as short as possible.
In version 2.20 I changed colors and added taskbar icon for representing the ticktimer status when application is not active thanks to requests from users.

Like the app, as already mentioned sounds seem missing and prevent to sleep setting is reactivated after reset of device and restart of program. The consequence is that my display keeps running and that consumes more energy.
