About Sun to Moon Sleep Clock
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 time to wake up. Throughout the night, 26 stars disappear one by one, giving children a simple visual countdown until morning. The app is quick to set up, fully customisable, and includes optional sleep sounds, wake-up sounds, naptime timers and bedtime-routine tools.
Children can personalise 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 children 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 the 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 change to your usual routine? Tap Moon’s nose three times for an out-of-schedule sunrise — and three more times for an immediate sunrise.
