Description by ao-system, Inc. Written by the developer, not by AppBrain. Click to read.
Discover your high and low periods by tracking your 23-day physical, 28-day emotional, and 33-day intellectual rhythms. By understanding your cycles, you can better seize opportunities and stay cautious during unstable times.

How it works:
- High Curve: Period of peak performance and advantage.
- Low Curve: Challenging days where caution is advised.
- Center Line: Unstable transition days requiring extra attention (Critical Days).

The concept was proposed by German surgeon Wilhelm Fliess in 1897. While regarded as pseudoscience due to a lack of statistical evidence, it remains a popular and fun tool for self-reflection.

Features:
- Register up to 5 birth dates: Enjoy it with family and friends.
- 38-Day Graph: View your rhythm starting from today.
- Risk Diagnosis: Identify critical days to avoid potential dangers.

Recent changes:
Improved overall stability and performance.
