Description
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.

It is a very great app, I really like it. My only issue is that the sounds break off and discontinue playing. Even when I put it on infinite play, the sounds and tunes play for about fifteen minutes or so, then completely cut out. I really hope this gets fixed soon. I mostly downloaded this for my nephews because they have trouble sleeping in the quiet (as well the dark) they complain that the music and sounds don't work anymore, many times, I check it out, and they're right. Please fix. Thanks.

This app works wonders for our 3.5-year-old. I recommend it for anyone who had trouble with their toddler waking up early in the morning and not knowing it's still the middle of the night. Developer is very responsive to improvements too!

I just uploaded this for the white noise option. It would not play continuously, as the option states it would. It also has an obvious gap in sound that is terrible for someone trying to sleep. It has bugs, I had to refresh the settings like brand new three times to get it to do what I wanted. Needs some work.
