Fall asleep to your own mix. Wake with a gentle reminder. Renight is a bedtime studio for winding down with synthesized soundscapes and planning a local wake reminder — not a medical device. SYNTHESIZED SOUNDS Mix rain-like, forest-like, fire-like, fan-like, ocean-like and bowl textures, plus white, pink, and brown noise. A sleep timer fades the mix out. BRAINWAVE BEATS Play Delta, Theta, Alpha, Beta, or Gamma monaural beats. Optional quieter carrier if you are sensitive to tones. WAKE REMINDERS Plan bedtime and wake reminders in 90-minute steps. A 30-minute reminder can send one additional local notification; it does not start audio automatically. Local notifications may not arrive if the app is closed, the phone is silent, or Focus is active. On iOS 26+, wake alarms can use AlarmKit. Still use the iOS Clock alarm too. BREATH & SESSIONS Pace 4-7-8, box breathing, and longer exhales with a glowing orb. Synthesized sound sessions and short sleep notes help you close the day. JOURNAL Log duration and quality. See a weekly average and a self-entered sleep-debt estimate versus an 8-hour target; this is not a medical measurement. Renight Pro is optional. Auto-renewable monthly and yearly plans (with free trials shown in the paywall) and a lifetime non-consumable unlock are billed by Apple. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions renew unless auto-renew is turned off at least 24 hours before the end of the current period. Manage in iOS Settings → Apple ID → Subscriptions. Unused trial time is forfeited if you buy during a trial. Prices vary by storefront.
