All data stays on your device. Ultradia uses Apple HealthKit to read your heart rate variability and activity data – nothing is uploaded or shared.
The science
Ultradian rhythms (specifically the Basic Rest-Activity Cycle) have been studied since the 1950s. Research shows these ~90-minute cycles affect alertness, cognitive performance, and physical readiness. By tracking the physiological markers of these cycles, Ultradia helps you work with your biology rather than against it.
Requirements
Apple Watch required for rhythm detection
Best results after 3+ days of continuous wear
