Talk with a healthcare professional before considering fasting, especially if you are under 25, pregnant or breastfeeding, take insulin or diabetes medicines, take medicines that require food, have a seizure disorder, work night shifts or operate heavy machinery.

Understand your nights with a sleep score, estimated sleep debt, stages and a routine that fits your life. Moonrise turns Apple Health records or manual sleep logs into clear, on-device insights. WHY MOONRISE • Your data stays yours — every score, debt figure, and correlation is computed on your device. No account or ads. Apple processes purchases. Optional purchase reporting sends RevenueCat purchase information and technical request information, including a vendor device identifier, after you allow it. You control exports and sharing. • Your sleep over time — review recorded nights by week, month, or year. • Numbers with meaning — a plain-language read on each night. WHAT YOU GET • Nightly sleep score — one number for the night, broken into duration, consistency, and restfulness so you can see what moved it. • Sleep debt — a rolling estimate of the rest you're carrying, with recent nights counting more. A wellness estimate, not a medical figure. • Wake alarm — set a wake time and optional early-wake window. Early wake uses an awake signal from Apple Health when available; it does not predict your live sleep stage. Your scheduled alarm remains the fallback. • Sleep stages — a clear, stepped view of awake, REM, core, and deep sleep for each night. • History — every night by week, month, or year, with the trend in view. • Wind Down — a calm pre-sleep step to help you land your bedtime. • Nightly habits & check-ins — tag caffeine, exercise, screens, a late meal, or a nap, and note whether you felt rested. • Free CSV export — take all your data with you, any time. MOONRISE PREMIUM Unlock habit correlations ("what helps"), weekly and monthly reports, week-over-week comparisons, and a 30-day rhythm view. A 7-day free trial, then an annual subscription — or a one-time lifetime purchase, no subscription at all. Moonrise reads your sleep from Apple Health with your permission, and writes back only the entries you add by hand. Every score, every debt figure, every correlation is computed on your device. Moonrise has no account or ads. Apple processes purchases. Optional purchase reporting sends RevenueCat purchase information and technical request information, including a vendor device identifier, after you allow it. Sleep data is processed on your Apple devices. Apple backups and Health synchronization follow your Apple settings, and you control exports or sharing. Removing the app does not delete Apple Health or purchase records. Moonrise supports wellness awareness. It is not a medical device and gives no medical advice, diagnosis, or treatment. Sleep scores and sleep-debt figures are estimates. — SUBSCRIPTION & PURCHASE DETAILS Moonrise Premium (Annual) — $29.99 / year with a 7-day free trial, an auto-renewable subscription. Moonrise Lifetime — $39.99, a one-time purchase (not a subscription). Payment is charged to your Apple ID at confirmation of purchase. After the 7-day free trial, the annual subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours prior to the end of the current period, at the price above. You can manage or cancel your subscription in your Account Settings (Settings › Apple ID › Subscriptions) after purchase. Any unused portion of the free trial is forfeited when you buy the subscription.

Verdict
The clearest difference is in-app purchases: Fasting Window at none against Moonrise's 2. Fasting Window also leads on iOS requirement (13.0 vs 26.0). Moonrise's advantage is update cadence (monthly vs every 2 months). On price, ads and device support there is nothing between them.
