## What is Circadran?

Circadran is your body dashboard to optimize your day and improve your health with your personal circadian cycle.
With Circadran you will no longer mistreat your body by asking it to perform in your cycle phases physiologically unfavorable and recover a good shape by monitoring your BMI. 
Circadran displays each metabolic phase in real time throughout the day.
When a user provides permission for Circadran to use health data to his Health app, Circadran becomes a valuable data source to centralize and compute health and fitness solutions. The intersection of risk factors highlighted by Circadran with the information provided by the health kit such as heart rate (watchOS), could be essential for the user.
Unfortunately since watchOS 7.3 Circadran can no longer stay in foreground for access to the sensors of the Apple watch allowing to calculate cardiac repolarization and arrhythmogenesis governed by circadian rhythms. Waiting for Apple to fix it, this feature is not anymore available.
