Sun to Moon Sleep Clock helps kids measure how far through the night they are and offers a few gentle incentives to keep them in bed till morning.
Set the sunrise time and tap 'Goodnight' then watch as stars are removed at regular intervals. Snooze Rewards are earned for every hour spent in bed, which can later be exchanged for gifts for the Sun and Moon characters.
As well as intricate hand-drawn artwork by artist Michael Sibley, the app also offers soothing sleep sounds such as whale song and white noise and a selection of fun wake-up sounds to celebrate the start of a new day.
If you have any feature requests or ideas about how I could improve the app please let me know by emailing email@example.com. You can also keep up to date by following Sun to Moon Sleep Clock on Twitter or visiting the Facebook page.

Instructions for use
Make a cardboard stand and hologram viewer for Sun to Moon Sleep Clock Find out more...
At its most simple you just open up the app, set a sunrise time and click 'Goognight'. The moon will gradually fade in accompanied by a series of 26 stars. The stars will be removed at regular intervals throughout the night until the wake-up time arrives and the sun rises again.
All additional features can be accessed from the settings menu.
If you want to just set the clock up and leave it running you can set a sunset time as well as a sunrise time. Click the yellow digits to select the hour, minute and AM/PM.
Tip All yellow digits on the settings page can be clicked to change a setting.
Sleep and Wake-up sounds
Select from various sounds to sleep to including hairdryer, waves, whale song and rain.
Wake-up sounds include a digital alarm and bird song.
All sounds can be silenced by clicking the mute button that appears in the top left corner when a sound is playing.
You may notice a small counter in the top left corner of the app which shows how many Snooze Rewards have been collected. Snooze Rewards are earned at the rate of 1 per hour whilst the moon is displayed and can be accumulated to buy gifts for the Sun and Moon characters. Accumulated Snooze Rewards are only banked at sunrise (or nose tap) to encourage children not to press buttons on the device before they are allowed to get up.
The following setting are available relating to Snooze Rewards and gifts:
1) Show | Hide - If you do not want any evidence of the Snooze Rewards to be present on the main clock screen (day or night), they can be hidden using this setting. Coins are still accumulated and can be accessed at a later date by selecting 'Show'.
2) Adjust coin balance - Whilst coins are always accumulated during the night, you are also able to adjust them manually. Just click the plus or minus icons and select the quantity of coins you would like to add or remove.
3) View Sun/Moon Gifts - Once some rewards have accumulated they can be spent on either Sun or Moon gifts.
Sun and Moon Gifts
Snooze Rewards can be spent on either Sun or Moon gifts including hats or disguises.
The price of items is displayed in the top left corner and each panel's status is indicated as follows:
1) Greyed out - You do not have enough coins to buy this item yet. Keep sleeping!
2) Not greyed out - You have enough coins to purchase this item. Just tap it and confirm the purchase to activate the item. Note: any other active purchases in the same group will be de-activated but can be reactivated at any time.
3) Cross - You have already bought this item but it is not currently active. Tap the panel to activate the item. Note: any other active purchases in the same group will be de-activated but can be reactivated at any time.
4) Tick - You have already bought this item and it is currently active. Tap it if you wish to deactivate it.
Birthday Countdown and Christmas Night
Sun to Moon Clock contains artwork and sounds specifically designed for Birthday and Christmas nights. Just add enough Snooze Rewards for all the items then visit the corresponding gift pages, selecting the appropriate items.
Sounds include a happy birthday song, a Santa wake-up call and the jingle of sleigh bells. You can also select alternative progress bars and countdown counters.
I find it useful to let our kids know when they are allowed to switch on the light and read if they wake up a bit early in the morning.
You can set how long they are allowed to read for and whether they can read in the morning, evening, both or neither.
When their reading time is active the moon will be reading his book rather than sleeping.
Twinkling Star Countdown
I received feedback that for some children, the time it takes for the last star to disappear seems like an eternity.
That's where the twinkling star countdown can help. Set the duration of the countdown and a randomly scattered group of twinkling stars will appear at the end of the night and disappear at much closer intervals than the standard stars.
Nose Tap Sunrise
If you have nearly made it through till morning but someone is wide awake and showing little signs of wanting to go back to sleep, you might want to call it a day and instigate an early sunrise.
To do this, just tap on the moon's nose 4 times in quick succession. By default the sun will rise immediately but you can add a delay to the sunrise in the settings.
You will know that the emergency sunrise has been instigated because the moon's nose will glow red.
This feature can also be used for short naps and other situations where you may wish to instigate a delayed sunrise without having to adjust the main night-time sunrise settings.
Settings Pin Code Lock
If you would like to secure the settings area of the app from inquisitive tapping then please turn on the pin code lock. Click each digit in turn to set your pin code. If you forget you code then a master code of 8529 can always be used to gain access.
Once this has been activated you will be asked to enter your pin before the settings screen is opened.
Dim, Dark and Auto Dim
As well as adjusting your device's brightness settings you can also dim the screen still further by selecting the 'Dim' option.
If you wish to dim or un-dim the screen without entering the app settings, you can do so by tapping the clock digits 3 times in the area shown below.
Alternatively, you may wish to activate 'Auto Dim' which will dim the screen half an hour after sunset and brighten it again half an hour before sunrise.
Dark mode can be used independently or in tandem with dim mode, and removes the blue tint from the night-time background to reduce glare.
When turned on, hologram mode optimises Sun to Moon Sleep Clock for use with a hologram viewer.
The hologram viewer is an adaptor that can be attached to your sun clock stand to give the impression of Sun and Moon hovering in mid-air.
