Biorcal is a total biorhythm calculator. It calculates all the 13 known biorhythms for the present date and time, at any specific moment, or, during a certain time period.

Extra Biorhythms

The time period diagrams of the application provide the ability to calculate the arithmetic value of any biorhythm at any moment, by just touching the relevant point of the corresponding curve.
Time period calculations cover a range from 1 to 100 days. The range and the start date are selected by the user. Also, the user is able to choose and print the curves that he/she wants.
The user can select between the Classic and the Extended option of biorhythms. The last option takes into account not only the Infradian component (as Classic Biorhythms do) but also the Circadian and Ultradian ones.
