iCloud sync
GymBook syncs data through your private CloudKit database. Sign in to iCloud, enable iCloud Drive, use the same Apple Account on both devices and allow some time for the first sync. The Settings screen should display “iCloud sync active.”
Previous weights are missing
Placeholders are generated from completed sets. Mark the set as completed and finish the workout using the Finish Workout button. Matching exercise names share history across different days and programs.
Body measurements
Body-fat results are estimates based on the measurements you enter, not medical diagnoses. For consistent charts, measure under similar conditions each time.
Reset all data
Profile → Settings → Reset All Data deletes programs, workout history, measurements and custom exercises. When iCloud sync is active, deletions may propagate to your other devices. This action cannot be undone.
