Natural Biorhythm

Have you ever wondered whether today's job interview, exam or date is going to be a success?
Knowing your biorhythm helps you to have a clear idea of what you can except from each day! It helps you to understand when you are at your full potential and it prevents you from making rash decisions during your critical days.

Compute your daily Biorhythm with this simple application.

I developed the application for my high school thesis. However this does not mean that I am not still working on improving the app! Please leave your feedback in the comments or write me an email and I will try to implement your ideas as soon as I possibly can. For your comfort I did not add any annoying advertisements or splash screens.
Any help is greatly appreciated!
