Help your kids learn when it's time to get out of bed with Sun to Moon Sleep Clock. 26 stars are removed at regular intervals through the night, helping them gauge how long it is until morning.

Customize the Sun and Moon characters with outfits, accessories and sounds or enable Snooze Rewards so that the longer your kids sleep, the more items become available to them.

Bedtime and wake-up time can be set from the settings page or by tapping the time digits on the main daytime screen and hitting 'Goodnight'. One-off naps can be triggered by tapping Moon's nose 3 times or tap it 6 times for an immediate sunrise.

• Sleep Clock stand & Hologram mode - Get crafty and make your device little-finger-proof with a Sleep Clock stand and hologram adapter. The Sleep Clock stand covers the device's physical buttons whilst hologram mode takes it one step further and gives the impression of Sun and Moon hovering in mid-air. Full instructions for creating your bespoke stand and hologram viewer can be found on my website at, where you will also be able to download templates.

Note: Please ensure your device is plugged in and that notifications are silenced whilst using this app. If you forget your settings pin the master code is 8529. If using this app on an OLED screen (the iPhone X for example), it is a good idea to reduce the screen brightness and enable auto-dim mode for long periods of use.

If you find the app useful or have any suggestions then I would really appreciate a rating/review in the App Store. Positive reviews encourage me to keep working on the app and constructive feedback provides me with new ideas that I always try to implement if possible. Thank you!

Best app for early risers who can’t tell time

My son is for, and can’t tell time. He was waking up super early and waking up the baby. We got this app and that night/morning he understood the concept and did not get out of his room until the sun came up. The baby slept, we slept, my four-year-old slept, this app is the best thing since sliced bread!

Great app!

This app is the perfect equivalent to our well loved Gro-Clock but even more portable! Really helps kids understand how much longer until it is time to get up - highly recommend! Exactly what I was looking for :)

Like it, closest to "kidsl**p blue bunny clock" that I have found.

We have been using " Kidslee* Blue Bunny Clock" for about 7 months. I SOOO wish that I had found this first. This pretty much has everything that I use, with some extra stuff that seems to make sense. That blue one was $50 +sh. This has pleasant smiling characters (sun and moon). Countdown to character change, dimming, and alarm Or no alarm. I do not like the nighttime go to sleep music though. Whale song, hairdryer, rain,etc. My preference would be a harp playing lullaby type music that could be set to incrementally decrease in volume. I also do not like that the gear(settings) is so visible to my child, most of the child apps have a code such as a math problem to get into settings. My child loves to change the numbers, sadly, he saw me access settings only once. YES! I would recommend this app.
