Luten
Sound for the mind.
Tell it how you feel and press play. No meditation course, no homework.
Just Press Play
The right sound for how you feel.
Not guided meditation. Functional, designed sound that meets the moment you are in. Five needs, one tap away, with a real soft spot for ADHD and busy minds.
Sleep
Brown noise, rain, ocean and low steady beds for the middle of the night, plus world lullabies, a sleep timer and a sleep score built from your Apple Health data.
Focus
Steady study music and focus sound with no lyrics, from cafe and library ambience to pink noise, with a one-tap focus timer to protect the session.
Stress
Slow, calming sound for stressful days, from ocean and forest to soft ambient, plus simple guided breathing to bring you back down.
ADHD
Steady, low-surprise sound made to help you settle, tune out distraction and stay on task, including brown noise and white noise, with a Pomodoro-style timer. Built with ADHD minds in mind.
Kids
Gentle lullabies, white noise and soothing bedtime sounds for little ones, with an auto-stop timer and a built-in safe-volume reminder.
How It Works
How Luten works.
Four steps, and the first two take a few seconds.
Why It Feels Different
Not another meditation app.
No voice to follow, nothing to get right. You press play, and the sound does the work.
Functional sound
Utility sound for a job, sleep, focus or calm, not a meditation course.
World soundscapes
Cultural and world sound worlds you will not hear anywhere else, designed by intent rather than picked at random.
Made for ADHD
Built with ADHD minds in mind, a quiet anchor for restless, easily distracted attention.
No pressure
It stays in the wellness lane, relaxation, focus and rest, with no homework and no streak guilt.
Luten or a Playlist
When Luten is the right choice.
A music playlist and Luten both put sound in your ears. They are built for different jobs.
The Signature
Two things you feel right away.
The heart of Luten: Sona, who learns what to play for you, and a sleep score that tells you the truth.
Sona, your sound companion
Tell Sona you are tired, wired, anxious or cannot focus. She listens, meets you where you are, and recommends a real track by name, then learns what actually settles you. She runs entirely on your device, so nothing you type ever leaves your phone.
Real sleep score
An honest 0 to 100 score built from your Apple Health sleep, with a full breakdown of duration, deep, REM and interruptions, plus vitals like heart rate, HRV, respiratory rate and blood oxygen. No vanity numbers.
What's Inside
More than a play button.
A considered set of tools that work together, quietly.
An evolving mix that crossfades between tracks across a session, not one file on loop.
No menus to read at 3am. The Luten mark turns slowly and breathes with whatever is playing, on a black screen that stays dark at night.
Background play, offline downloads, looping and continuous routines that keep going instead of stopping after one track.
Wind-down and daily ritual nudges, plus a soft come-back reminder. Calm prompts, never a jarring alarm.
A short starter program and gentle streaks to build a calming habit, without the guilt.
A home-screen widget, an Apple Watch companion and iMessage stickers.
Two to four members, each with their own space. Your profile syncs to the cloud and survives a reinstall.
Design
Calm you can feel.
An Apple Liquid Glass interface over a living sky that moves with your day: blue at noon, purple at dusk, deep violet at night, with the sun and moon arcing overhead. Premium, quiet, low pressure.
The Practical Part
What you should know.
Honest details, no fine print games.
Questions
Questions, answered.
What is Luten?
Luten is an iOS app that plays sound for sleep, focus, ADHD, stress and kids, and learns which sounds you actually stay with. It is made by One Life. The name is pronounced LOO-ten.
Is Luten a meditation app?
No. Luten is functional sound, not guided meditation. You tell it how you feel and press play. No course, no breathing homework, no gurus.
What sounds help you fall asleep?
People often choose steady sound with no beat and nothing that builds or drops: brown noise, pink noise, rain, ocean, fan hum and low held tones. Which one suits you is personal, so Luten lets you try them and puts the ones you keep playing first. It also shows a sleep score built from your Apple Health data so you can see your nights.
What is the difference between white noise, pink noise and brown noise?
White noise has equal energy at every frequency, so it sounds bright and hissy, like static. Pink noise has less energy as the pitch rises, so it sounds softer and more even, like steady rain. Brown noise drops off faster still, so it sounds deep and rumbling, like a waterfall or strong wind. Luten includes all three, each synthesised to its true spectrum.
What sound is good for focus while working?
Many people work to steady sound with no lyrics and no sudden changes, such as cafe or library ambience, pink noise, brown noise, steady rain or soft instrumental study music. Luten's Focus mode plays that kind of sound and starts a focus timer, and ADHD mode adds a Pomodoro-style timer.
Can sound help an ADHD or busy mind focus?
Luten's ADHD mode plays steady, low-surprise sound with a timer, made for a restless mind. It is a wellness tool, not a medical device, and it does not treat any condition.
How long should you listen to sleep sounds?
There is no set length, and Luten does not prescribe one. Let a sound play until you stop it, or set a sleep timer so it fades out after the time you choose.
Is it safe to play sleep sounds all night?
Luten can play all night with the screen locked, or stop on a sleep timer that fades the sound out. Every sound is instrumental with even loudness, so nothing jumps in the night. Keep the volume low and comfortable, and ask a doctor if you have questions about your hearing or your sleep.
What makes Luten different from other sleep sound apps?
Luten is sound, not guided meditation: you say how you feel and press play, with no course to finish. It covers sleep, focus, stress, ADHD and kids in one app, every sound is instrumental with even loudness, and Sona, the companion that suggests sounds, runs on your iPhone. It also shows a sleep score built from your Apple Health data.
Does Luten work without a connection?
Yes. Download the sounds you want and they play with no signal, on a plane, in a basement, anywhere. Nothing has to buffer before it starts.
Does Luten keep playing when I lock my phone?
Yes. Playback carries on with the screen off, with full controls on the lock screen and in Control Center, and a sleep timer if you want one.
Does Luten send my data anywhere?
Sona, the companion you talk to, runs entirely on your iPhone using Apple's own on-device language tools. What you type stays on the phone.
