Following biorhythm

I have followed my rhythms daily for 20 years. Because they help me distribute my limited energy to the activities; it’s like riding on the crest of a wave, which promises the best outcomes.

Accuracy plus

Accurate app. I don’t check every morning, but do when I’m having a depleted day and figure out it’s normal. I love being able to combine family groups and checking the rhythm before a visit or event. Worth the investment.

I love it!!

I live with my long time girlfriend and her sister. The ability to AVERAGE all three of us is great !!! Used a lot of these program for many years - all the way back to versions in basic - and this is by far the easiest, fastest, in doing exactly what it's supposed to!

FAQ

What does this app do?

It uses your birthday to predict your potential for stamina, judgment, and emotion, offering insights into optimal times for activities and advising caution during low or dangerous periods.

How are biorhythms calculated?

Biorhythms are calculated using formal algorithms based on your birthday. The app tracks four cycles: physical (23 days), emotional (28 days), intellectual (33 days), and intuitive (38 days). Each rhythm is represented by a value from -100 to +100, indicating high, low, or dangerous stages.

Is this app free to use?

Yes, the application is free to use. There are no in-app purchases or advertisements mentioned in the provided description.

Can I track biorhythms for multiple people?

Yes, the app supports integrated management of multiple users' biorhythms. You can easily switch between users and view their individual biorhythm graphs and analyses.

What are 'Dangerous Days'?

Dangerous Days are identified as the moments when a biorhythm cycle transitions from a positive value to a negative value, or vice versa. The app highlights these transition points, suggesting that it may be advisable to avoid unreasonable activities during these times.
