Biorhythm support

You guys should integrate biorhythm support directly into the app. Both old and improved models and then make suggestions based on the average of both models. Also a winding graph based on both models would be helpful.
A system that tracked ailments based on weather, moonphase and biorhythm altogether would be cool.
For instance here are two examples a headache tracker based on both moon phase and barometer and biorhythm. Or a allergy graph based on weather and biorhythm.
Just some ideas.
