Helps children sleep and know when it's time to get up.

Upcycle your old android or iOS phone or tablet into a sleep trainer with the Sun & Stars app.

Sleep and Wake

When it's time to wake up, the app will automatically switch from the dark screen with the moon to a bright yellow screen with a sun, and will also play the music selected in the settings screen.

It's not time to get up until the sun comes out!

At night time, the moon communicates sleep, and soothing music can be played by tapping the screen.


Set time to wake up, and time to go to sleep.

Choose how long to play music for on wake time, sleep time, or screen tap.

Choose between no sound, original music by L. Chenier, the white noise of a fan, or a playlist from iTunes (iOS only).

Try it!

Tap on the stars below to hear the built in music, and tap on the moon to switch to wake mode.
This is the app in fullscreen mode:

Note that the stars appear more gradually over time in the actual app
