Two friends. Two little worlds.
Who will say goodnight tonight?
A moonlit clearing with Lumi. A quiet corner of the sea with Otto. Each has a familiar voice and stories to return to.

The moonlit clearing
Lumi
Leaf boats, small lights and gentle rain. Little adventures told at an unhurried pace.

The quiet deep sea
Otto
Kelp gardens, hidden paths and a pearl to carry home. A softer side of the underwater world.

Your evening, with a softer ending
Pyjamas. A story.
Then quiet.
After teeth are brushed and the lights are low, choose a story together. A small moment you can make your own, night after night.
- Choose togetherPick Lumi or Otto, then a story. No sign-up stands between you and the first goodnight.
- Listen for about five minutesSlow narration, gentle pauses and quiet music. Towards the end, there is less happening and less to follow.
- Let the evening endThe scene darkens and the music fades away. No next episode, no new choice to make.
Designed to wind down
Less to watch.
Less to listen for.
As the story unfolds, the whole little world becomes quieter.
- An unhurried voiceSlower than everyday conversation, with soft pauses that give each sentence room.
- Gentler motionLumi and Otto breathe and sway. Their movements grow smaller as the scene gradually darkens.
- A gradual goodbyeMusic stays behind the voice, then fades out slowly after the final words.

Behind the design
Thoughtful choices.
Open reasoning.
We describe what Mightlings does, not what it will do to your child's sleep. We haven't run a clinical trial on the app, and we don't promise a sleep outcome.
No 432 Hz tuning, solfeggio frequencies or binaural beats. We do not present these as proven sleep aids.
Our design notes explain the research we read, the choices we made and the limits of the evidence.
Is Mightlings free?
Yes. The current version is free to download and use, with no ads or in-app purchases.
Can we listen without watching the screen?
Yes. The story keeps playing when you lock the screen. You can listen together with the phone set aside.
Can we use it without internet?
Yes. Stories play from your device. Open the app and make sure your chosen story is ready before using it somewhere without a connection.
Can we return to the same story?
Of course. Choose a familiar friend and story each evening if you like. There are no streaks, scores or rewards to keep up with.
Where are the parent settings?
Press and hold the settings button to open the parent controls for language, volume and the sleep timer.
