Well, it works pretty simple, it only helps you to control exercising.
All you need to do:
* cut a small circle out from a black paper (about 5 mm diameter)
* glue it on a window, in your room
* stand right in front of it, at the distance of 30 sm
* start application (so it will start counting)
* look at the circle on the window for next 30 seconds
* after 30 seconds the application will make a noise sound
* now you need to look for a long distance, for next 30 seconds as well
* you have to repeat this exercises for next 5 minute , each day
Note: you may increase the time of the exercise each day by 1 minute, but not longer than 15 minutes are allowed
So as you see, this application works only as a timer, nothing more, thats why I've said that it's a pretty small app.
I hope this helps.
Edit: I've edited the name of the thread, so it doesn't look like this application contains any kind of an exercises.
