BioCalendar counts your three biorhythm cycles from the day you were born and gives you a written reading for every day. It is a biorhythm calculator that does the counting for you, and a calendar that shows your critical days.

The physical cycle runs 23 days, the emotional 28 and the intellectual 33. Each passes through the same eight states, from its high through a critical day to its low and back. Where the three sit today chooses one of 512 written readings. Read yours in the morning, then notice how the day feels against it: a few minutes of reflection, every day.

YOUR DATA
Your date of birth is the one thing BioCalendar needs, and it never leaves our servers. The personalised and monthly readings and the Companion are written with an AI provider, and only if you allow it; your name, email address and date of birth are never sent to it. You can delete your account, and everything in it, from Settings, or at https://biocalendar.net/account-deletion/.

WHAT BIOCALENDAR IS
Biorhythm theory is not supported by scientific studies, and BioCalendar does not claim otherwise. For educational, informational and entertainment purposes only. Not advice, and not a prediction.

NEW IN VERSION 3
BioCalendar 3 is a new app, built from the ground up. Accounts from earlier versions are not carried over: please create a new account when you open it.
