Biorhythms with friend

Calculate your and a your friend's biorhythms to find the best common days.

The theory of biorhythms is a theory that claims our daily lives are significantly affected by rhythmic cycles.

According to the theory of biorhythms, a person's life is influenced by rhythmic biological cycles that affect his or her ability in various domains, such as mental, physical and emotional activity.

These cycles begin at birth and oscillate in a steady (sine wave) fashion throughout life, and by modeling them mathematically, it is suggested that a person's level of ability in each of these domains can be predicted from day to day. The theory is built on the idea that the biofeedback chemical and hormonal secretion functions within the body could show a sinusoidal behavior over time.

23-day physical cycle, 28-day emotional cycle and a 33-day intellectual cycle.

Each of these cycles varies between high and low extremes sinusoidally, with days where the cycle crosses the zero line described as "critical days" of greater risk or uncertainty.

The numbers from +100% (maximum) to -100% (minimum) indicate where on each cycle the rhythms are on a particular day. In general, a rhythm at 0% is crossing the midpoint and is thought to have no real impact on your life, whereas a rhythm at +100% (at the peak of that cycle) would give you an edge in that area, and a rhythm at -100% (at the bottom of that cycle) would make life more difficult in that area. There is no particular meaning to a day on which your rhythms are all high or all low, except the obvious benefits or hindrances that these rare extremes are thought to have on your life.

With this app you can also compare your biorhythms with a your friend's biorhythms, to search best days to approach your friend.
