Screens show example data and Premium features. Sleep stages and overnight vitals depend on available Apple Health records.
Moonrise refreshes available Apple Health records when you open the app and when Health delivers updates. A recorded night can appear as Sleep so far before your planned wake time. Availability depends on Apple Health and your sleep source.
Choose a scheduled wake time and, optionally, an early-wake window. Early wake responds to an awake signal from Apple Health when available. Your scheduled alarm is the fallback. This feature does not predict your live sleep stage.
No. You can use compatible sleep records in Apple Health or log sleep manually. Detailed stages and overnight sensor readings require a source that records those measurements. CSV export is available in Settings.
Premium adds deeper habit insights, reports, comparisons, rhythm views, and bedtime app blocking. New users need an eligible trial or purchase to complete setup. Annual and lifetime options, current local prices, and any trial eligibility are shown in the App Store purchase flow.
Sleep and Health data are processed on your Apple devices. Optional onboarding events go to PostHog only after you allow sharing, and optional purchase reporting goes to RevenueCat under a separate choice. You control exports and support messages. Read the full privacy policy.

Sleep scores and debt are wellness estimates. How you feel matters, too.
