Have you ever wondered why you have up and down days? Maybe you’ve felt like sometimes you were not in control of your life. Theories created in the late nineteenth and early twentieth centuries describe three fundamental energy cycles that effect humans to varying degrees. LifeRhythm lets you chart your biorhythm for any day and post it to your Facebook wall. You can also chart the biorhythms of your family and friends.

Biorhythm cycles oscillate between a positive phase and a negative phase, during which the related trait’s energy level strengthens and weakens. A critical day occurs when the cycle moves from positive to negative or vice versa. Traits associated with the critical day’s cycle are far more erratic than on other non-critical days. Cycles that are in a negative phase are not necessarily bad. It is simply a relatively lower energy level than the positive phase.

Knowledge of your biorhythm may help explain your current or past emotional, physical, and/or intellectual states. Knowledge of your possible future states may help you to schedule your daily events and activities to take advantage of your specific rhythms.

LifeRhythm works with all versions of iPhone and iPod touch.
