Great update!

As of latest update (Dec 2025) no idea how it is calculating biorhythms, other than incorrectly.

FAQ

What is myBiorhythm?

myBiorhythm is an application that visualizes your personal biorhythm cycles, including mental, physical, and emotional activity, based on your birthday. It helps you understand your predicted ability levels for any given day and year.

What are the key features of myBiorhythm?

Key features include visualizing biorhythms for specific dates, an overview of the best and worst days of the year, an Apple Watch app for quick access to percentages and icons, a database to store and manage multiple birthdays, and a group module to view median values for groups of people.

How much does myBiorhythm cost?

The app offers a free version that provides primary biorhythm values. Users can upgrade to the full version via an in-app purchase to access additional values, combined lines, and a view showing the best and worst days of the year.

What is the theory behind biorhythms?

The theory of Biorhythms suggests that a person's life is influenced by rhythmic biological cycles (mental, physical, emotional) that begin at birth and oscillate throughout life. By modeling these cycles mathematically, the app aims to predict a person's ability levels in various domains on a day-to-day basis.

Can I use myBiorhythm on my Apple Watch?

Yes, there is a separate Apple Watch app that allows you to view your current biorhythm percentages and icons directly on your watch. You can see this information in a table view or as a complication for quick glances.
