Where Does Athlytic Store Training Data?
Athlytic recovery analytics over HealthKit with settings in app storage.
Last updated
Athlytic computes recovery, sleep debt, exertion and readiness from Apple HealthKit data and keeps its own dashboards, baselines and settings in the app with iCloud sync. The Watch feeds Health; Athlytic reads Health.
Baselines are the slow asset here. Weeks of history calibrate the recovery model, so a fresh install with full Health permissions still needs time before scores stabilize. Keep Health history intact across phone upgrades and the model recovers faster than starting cold.
Where Athlytic stores this, by platform
Apple HealthKit (source data) plus app iCloud store (baselines and settings)
Needs broad Health read access (workouts, sleep, HRV, resting HR). Subscription unlocks full analytics. Same Apple ID on Watch and iPhone keeps the pipeline intact.
Frequently asked questions
why are Athlytic scores blank after reinstalling
Baselines rebuild from HealthKit history over days, not minutes. Confirm Health permissions and iCloud sync, wear the Watch normally, and wait. Deleting Health history is the one unrecoverable mistake.
does Athlytic store workouts itself
No. Workouts live in HealthKit from whatever tracker recorded them. Athlytic stores derived metrics and preferences. Export from Health or the original tracker for portable files.
