Sun to Moon Sleep Clock is a gentle sleep trainer that helps toddlers and young children learn when they should stay in bed and when it’s okay to wake up.
Throughout the night, 26 stars fade away one by one, giving kids a simple visual countdown until morning. The app is quick to set up, fully customizable, and packed with optional sleep sounds, wake-up 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 positive sleep habits. The longer kids stay in bed, the more Snooze Coins they earn — which can then be exchanged for fun gifts for Sun and Moon.
Wake-up times can be adjusted in Settings or by tapping the orange digit 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 to trigger an out-of-schedule sunrise — and three more times for an immediate sunrise.
