You need sleep that's already recorded in Apple Health — by an Apple Watch or any compatible sleep tracker. Bedhead reads that data; it doesn't measure sleep itself. Without recorded sleep, there's nothing for it to show.

On purpose. A score compresses a whole night into one number that hides more than it reveals, and invites you to chase the number instead of resting. Bedhead shows you what actually happened — duration, stages, how you compare to your own average — and trusts you with it.

Free is seeing your sleep: last night against your average, your stages, tonight's bed-by time, your history against your target or your typical night. Premium is changing your pattern and watching it pay off: the Bedtime Plan, which walks you to your target bedtime a few minutes a night; the Trends tab — how steady your bedtime is, your weekend jet lag, month by month, sleep debt; what moves your sleep, comparing your own nights; overnight vitals — heart rate, HRV, breathing and wrist temperature against your usual range; the lock-screen and Home Screen widgets; and CSV export.

You set your wake time and a sleep target in Settings. Bedhead works backward to the time you'd need to be asleep tonight to hit that target — and, if you like, nudges you thirty minutes before.

Settings → Wind-down reminder. It's off until you turn it on, and you can switch it off any time.

Your sleep history stays on your device — each device reads it from its own Apple Health. Your settings and bedtime plan sync through your own private iCloud, under your Apple ID, with no sleep durations, stages or vitals in them. There's no Bedhead account and no Bedhead server — we never receive your sleep data. See the privacy page for detail.

Settings → Delete Sleep History removes Bedhead's stored history from that device. Your Apple Health data is untouched, and the last 30 days may repopulate from Health on the next refresh.

Settings → Restore Purchases. Premium follows your App Store account, so it should also appear automatically once you're signed in to the App Store (your Apple Account's Media & Purchases).
