Luna: Sleep Clock & Nightlight

Luna turns a smartphone you already own into a bedside sleep clock for your child, and puts you in control of it from your own phone.

HOW IT WORKS

Luna is one app with two modes. Install it on an old phone, stand it by your child's bed and pick Alarm Clock mode. Install it on your own phone and pick Parental Device mode. Pair the two with a 4 digit code and you are set up.

WHAT YOUR CHILD SEES

A big, clear clock and an animated moon character that shows whether it is still night or time to get up. A progress bar fills through the night, so a child who cannot yet read a clock can still see how much of the night is left.

NIGHTLIGHT

The edge of the screen glows in the colour you pick, from 12 presets. Set the brightness, and dim the clock itself so it does not light up the whole room.

BEDTIME SCHEDULES

Build repeating schedules: a bedtime, how long the night lasts and which days it applies to. Weeknights and weekends can be different. Each schedule turns the nightlight and the morning alarm on or off independently.

NAPS

Start a nap from your phone or from the clock itself. Anywhere from 1 to 180 minutes, with an optional nightlight and an optional alarm at the end.

LISTEN AND ANSWER

When your child calls out at night, hear the room from your own phone and answer them, without getting up. Tap Listen in and the room plays live. Put your phone away and the clock keeps listening for you, sending your phone a notification if the room gets loud, until you stop it. A small mark on the clock shows whenever its microphone is on. Nothing is recorded, and everything stays on your home Wi-Fi.

WAKE-UP SOUNDS

Seven alarm tones and eight wake-up music tracks. The volume ramps up gradually from silence, so nobody is startled awake. One tone is built into the app and works with no connection at all.

MUSIC AND STORIES

Send your own songs, lullabies and bedtime stories to the clock, as single files or a whole album in a zip. Luna reads the titles and the track order from the files, and everything copies over your Wi-Fi and stays on the clock, so it plays with no connection.

Queue an album from your phone and run the playback from there: play, skip, seek, volume, and a stop timer that ends the music after the current track, after a delay, at the end of the playlist or at bedtime, fading out over the last minute.

You decide what your child can do on the clock, control by control: hidden, daytime only or always. Albums and sounds carry a colour and a symbol, so a child who cannot read still picks the one they want.

FITS A 3D PRINTED CASE

Adjust the screen padding and the corner radius so the display lines up neatly inside a custom case.

PRIVACY

Your phone talks to the clock over your own Wi-Fi. The connection is encrypted, pairing is confirmed with a code shown on the clock, and there is no account to create. Your child's schedule, their nap, their nightlight, the sound of their room, the music you send and their name stay on your devices. None of it is sent to us and none of it is stored in the cloud. A noise alert only tells your phone that something was heard.

FREE

Luna is free. No ads, no subscription required, and every feature in the app today is available to everyone. You can chip in to support development if you want to, and it adds your first name to the supporters list in the app. It is a contribution, not an upgrade. Support is a one-off payment or a monthly one, and the monthly option renews every month at the price shown before you buy, until you cancel it in your App Store account settings.

WHAT YOU NEED

Two devices on the same Wi-Fi network: one to be the clock, one to control it. An old phone you no longer carry is exactly the point.

Luna speaks English, Spanish, Portuguese, German and French.
