Biorhythmics

Biorhythmics is a minimalistic, light, no-frills app that plots your biorhythm. You can check your biorhythm every time you like, and you can set an hour of the day to get notifications about your biorhythm status.

The app notifies you about positive and negative weeks of your biorhythms (Emotional, Intellectual and Physical), and crucially the critical days. All critical days including double and triple ones, are reminded one day before they happen, so you will be prepared for them!
