Health access lets RunSignal read live heart rate from Apple Watch during a run, read optional history for analysis, and save completed workouts to Apple Health. It’s optional: you can run without it, and missing signals are shown as unavailable rather than estimated.

Only when you tap Start Run. Location is used to record your route, distance, and pace, and continues in the background during an active run so the Live Activity stays accurate.

Open Profile → Settings → Analyze Health History. This is off by default. When enabled, the app analyzes your earlier workouts using samples already on your phone and adds zone, drift, and load metrics to them.

Check that the Watch app is installed (iPhone Watch app → Available Apps), that Health access includes Heart Rate on both devices, and that the Watch is unlocked and snug on your wrist. Heart rate appears in the phone app and Live Activity within a few seconds of the first Watch reading.

That’s fine. The latest reading reappears when the devices reconnect, and the app will not create a duplicate run.

Confirm Live Activities are allowed in iOS Settings → RunSignal. If the app was force-quit mid-run, reopen it — the active run is recovered and the Live Activity is restored or safely ended.

Yes — custom Live Activity layouts (three chosen metrics, units, calories, and optional zone guidance) are part of Lifetime Pro. The default layout is available to everyone.

Profile → Settings → Backup & Restore → Create Encrypted Backup. Choose a password of at least 10 characters and save the file to Files or iCloud Drive. The backup contains workouts, settings, raw samples, achievements, and local analytics.

Restore merges: runs that are missing on the device are added by ID, runs that already exist are left untouched, and your current device settings are preserved. On a fresh install, the backup’s settings are adopted.

The backup is encrypted with a key derived from your password and cannot be recovered without it — not by you, and not by us. Create a new backup from a device that still has your data.

Sign in with the same Apple Account, then open Profile → Settings → Lifetime Pro → Restore Purchases. Family Sharing members can use the same path once sharing is enabled by the purchaser.

The Today coaching workspace (private daily coach, daily readiness, recovery-aware load guidance) and custom Live Activity layouts. Run recording, live zones, history, run details, range reports, race estimates, awards, and backups stay free.

Purchases are handled by Apple. Request a refund at reportaproblem.apple.com; Apple makes the decision and processes it.

Delete individual runs from their detail screen, or delete the app to remove its local database and analytics files. Workouts already saved to Apple Health can be removed in the Health app. There is no server-side copy to delete, because RunSignal has no account or backend.

No. The coach runs Apple’s on-device model where available and a deterministic local fallback elsewhere. Your workout and recovery inputs never leave the device. See the privacy policy.
