Sun to Moon Sleep Clock is a gentle sleep trainer that helps toddlers and young children learn when to stay in bed and when it’s okay to get up. Throughout the night, 26 stars disappear one by one, giving kids an easy visual countdown until morning. The app is quick to set up, fully customizable, and packed with optional sleep sounds, wake sounds, nap timers, and bedtime-routine tools. Kids can personalize the friendly Sun and Moon characters with outfits and accessories from their shops. Everything is unlocked from the start, but you can enable the optional Snooze Rewards system to encourage healthy sleep habits. The longer your child stays in bed, the more Snooze Coins they earn — and they can trade them for fun gifts for Sun and Moon. Wake-up times can be set from the settings screen or by tapping the orange time buttons on the main daytime screen. Tapping Goodnight triggers an instant sunset at bedtime. Need an early wake-up for a nap or a schedule change? Tap Moon’s nose three times for an out-of-schedule sunrise — and three more times for an immediate sunrise.

Good Inside holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Good Inside has 14K ratings behind it against 107, so its average is the more settled of the two. Written reviews complicate that: 94% of Sun to Moon Sleep Clock's written reviews are positive against 85% of Good Inside's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Sun to Moon Sleep Clock ships an update every 2 months, Good Inside every 2 days. The most recent releases landed on November 6, 2026 and November 9, 2026 respectively.
