Based on the theory of Biorhythms, this app helps you chart your four cycles starting from the date and time of birth, including Emotional, Intellectual, Physical, and Intuitive. The theory was developed by Wilhelm Fliess in the late 19th century and became popular world-wide in the late 1970s.
With MyBioCycle you can track up to 12 different profiles to see if your friends and family are in synch with you. The app displays the classic sine waves in 4 different colors, showing up to one year ahead. The overview page displays your current position at a glance and lets you know which direction your cycles are moving.
