SlowpulseMy score is blank, or says "Still calibrating"
This is the most common one and it is almost always expected behaviour. Slowpulse needs about two weeks of readings before it has a baseline to compare against, and it specifically needs resting heart rate and HRV, which your Apple Watch mostly records while you sleep.
- Wear your watch overnight — this matters more than wearing it during the day.
- Check Health → Browse → Heart → Resting Heart Rate. If that is empty, Slowpulse has nothing to work from yet.
- Confirm permissions: Health app → Sharing → Apps → Slowpulse, and make sure every category is on.
Health permissions are the usual culprit. iOS never tells an app it was denied — the app simply receives nothing — so a missed toggle looks exactly like missing data.
The Apple Watch app shows no data
- Both apps need to be installed and opened at least once.
- Keep the watch on your wrist — it stops sampling heart rate when removed.
- Grant Health permissions on the watch as well as the phone; they are separate prompts.
- If the two disagree, open both apps with the devices near each other so they can sync.
I'm not getting stress alerts
Alerts are a Premium feature. Check that notifications are allowed in Settings → Notifications → Slowpulse, that alerts are enabled inside the app's own Settings tab, and that a baseline has been established — the app will not alert on data it cannot interpret.
Restoring a purchase
Open Settings inside the app and tap Restore Purchases. Purchases follow your Apple Account, so use the same one you bought with. Subscriptions are managed on your device in Settings → your name → Subscriptions.
Refunds
All App Store purchases are refunded by Apple rather than by us. Go to reportaproblem.apple.com, sign in, and choose the purchase. If Apple declines and you think that is unfair, write to us and we will do what we can.
Deleting your data
Delete the app. Everything it stored goes with it — there is no copy anywhere else. Readings in Apple Health belong to Health, not to Slowpulse, and are removed in the Health app.
Something else
