Tracks your biological circadian phase. Identifies your optimal windows for energy, focus, and sleep - then shows the transition between active and wind-down phases.
FIT file export, colored route maps with pace visualization, mean max power curves, and polarized training zone breakdown for serious runners.
Dose-response curves, Granger causality analysis, adaptation tracking, and Kalman-filtered recovery state estimation. What actually causes what in your health data.
Biological age estimation, VO₂ max tracking, DFA-α1 heart rate variability analysis, and circadian age (CosinorAge). Metrics that move, not just snapshots.
No cloud sync. No third-party SDKs. No ads. All analytics run on-device using GRDB.sqlite local storage. Your health data never leaves your phone.
