A little company. A little earlier to bed. Goodnight Kitty makes winding down feel gentler. Rice responds to your touch and remembers your recorded nights. MaiMai brings a quieter kind of company. Spend a moment together, choose a sleep sound, and say goodnight when you are ready. YOUR OWN BEDTIME Set one simple schedule, or separate workdays and rest days. Use an optional bedtime reminder and wake-up alarm. Start now or take a short wind-down before app limits begin. Strict mode adds a pause before leaving early; an exit is always available. SOUNDS THAT SETTLE DOWN WITH YOU Preview purring, nature sounds and quiet sleep music. Choose 1โ€“30 minutes of playback, with a gentle fade toward silence. The default is five minutes. A CALMER SLEEP JOURNAL See your nights on a calendar, record how you feel after waking, and add a short note when you want. With your permission, the app can read Apple Health sleep records, including compatible Apple Watch data. Bedtime plans and self-reported feelings are kept distinct from measured sleep. A CAT CLOSE BY Invite a partner through iCloud to share voluntary bedtime presence, only after they accept. Your cat can rest beside theirs without sharing app usage or your private journal. Choose a hand-drawn cat with its own little movements. Add a Cat companion or Tonight with kitty Home Screen widget. Start sleep mode in the app to see your cat on the Lock Screen and Dynamic Island through Live Activities, subject to iOS availability and time limits. THE ESSENTIALS STAY FREE Rice, MaiMai and Dot, the bedtime routine, app limits, strict mode, sleep sounds, journal and widgets are free. Optional Pro adds eight more cats and extra alarm chimes, with annual and lifetime options. Your journal and Apple Health records stay on your device. Optional iCloud companionship shares only your current voluntary companion status with someone you invite. No app account, ads or third-party tracking. Screen Time, alarms and Apple Health require the relevant system permissions. Goodnight Kitty supports a bedtime routine; it does not diagnose sleep or prove that you are asleep. Annual membership renews automatically unless canceled in App Store account settings. Any eligible trial and the renewal price are shown before purchase. Lifetime membership is a one-time purchase.
