Settle your mind.
Shape your night.
TritonSleep is a calm, private sleep and dream toolkit. Layer more than 45 relaxing sounds, ease down with breathing, affirmations and narrated wind-downs — read to you if you like — then record dreams and explore evidence-rated lucid-dreaming techniques. No ads. No account. No nonsense.
What you get
A library built for nighttime
More than 45 sounds and tones — rain and thunder, ocean and streams, wind, a crackling fireplace, quiet fans, white, pink, green and brown noise, night crickets, ambient pads, a soft heartbeat, a cat’s purr, gentle felt-piano pieces, and now a plane cabin, a train, a washing machine and a fridge at night — every one loop-tested so there are no seams to catch your ear.
Mix your perfect night
Layer up to five sounds — rain over a low fan, ocean under a soft pad, a generated tone beneath it all — balance each volume, and save your favourite combinations as one-tap mixes.
Drift off, not on
Sleep timers of 15 to 60 minutes with slow fade-outs from 30 seconds to 3 minutes — the silence never arrives suddenly. Audio keeps playing with the screen off.
New in 1.2: sounds, a voice, and nineteen languages
The everyday drones people actually fall asleep to, a calm voice that reads to you so you can close your eyes, and an app that follows your phone’s language.
Travel sounds
A plane cabin at cruise, a train carriage, a car on the motorway and a ship’s cabin — the steady hums that send people off on the move, now at home too. Sleeping on a plane or train
Around the house
A washing machine, a tumble dryer, a dishwasher and the hum of a fridge at night, plus rain on a metal roof and a heavier storm. Why fan and appliance noise works
Spoken guidance
Affirmations, wind-down prompts, breathing phases and technique steps can be read aloud, so you can close your eyes instead of watching the screen. Course days and technique explainers have their own Listen control. Off until you turn it on in Settings. Spoken guidance is in English.
Nineteen languages
TritonSleep now follows your phone’s language: English, Czech, Dutch, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Polish, Portuguese (Brazil), Russian, Simplified Chinese, Spanish, Thai, Traditional Chinese, Turkish and Vietnamese. The fourteen narrated wind-downs are narrated in English.
Dreams, privately
A private, on-device space for remembering dreams and building a lucid-dreaming practice without turning bedtime into another scoreboard.
Private dream journal
Write or record a voice note when you wake, add tags and dream signs, use the low-light night screen, browse by night on a calendar, search your entries, lock the journal behind a PIN, and export it whenever you choose. Entries stay on your device.
Techniques with context
Explore guided MILD, WBTB, SSILD, WILD, FILD and dream-incubation sessions with clear evidence ratings, overnight cues and an optional wake-back-to-bed alarm.
Build awareness gently
Spot recurring dream signs, set local reality-check reminders, follow the optional 30-day course, and review your own patterns without medical or guaranteed-result claims.
Dream and lucid-dreaming features are for general wellness, reflection and education only. Results vary, and the app does not diagnose or treat sleep conditions.
More than sounds
Breathe your way down
Guided breathing with a calm animated circle: Box Breathing, Slow Breathing, 4-7-8 and Calm 4-6 — or build your own custom rhythm. Turn on spoken guidance and each phase is read aloud, so you can breathe with your eyes closed. 4-7-8 and box breathing
A tone generator you can shape
Steady single tones and soft two-tone pulses, generated on the fly — start from a preset like Drift or Settle, or dial in your own frequency and blend it into a mix. Headphones recommended; keep it low and comfortable.
Wind-down routines & guided sessions
Five short routines that pair breathing with the right soundscape — Quick Reset, Mask Noise, Quiet Mind, Body Relax and Deep Drift — plus fourteen narrated wind-downs for a racing mind or a body that won’t settle. Pick one, press play, put the phone down. Building a wind-down routine
Quiet affirmations
Five gentle affirmation decks — Calm Evening, Letting Go, Gratitude, Self-kindness and Restful Night. One calm line at a time: read them, or have them read to you. How to use sleep affirmations
Learn the why
A small library of short, practical reads — how sound masking works, what the noise colours mean, why slow breathing calms you, and how to shape a sleep-friendly bedroom. No fluff, no medical promises.
Gentle reminders
An optional bedtime reminder nudges you when it’s time to wind down. It’s a local notification on your device — nothing is sent to any server.
Yours, privately
No account, no analytics, no content backend. Your favourites, mixes, dream entries, optional voice notes and history stay on your device. Microphone access is requested only when you choose to record a voice note. Subscriptions are handled by the app stores — we never see your card details.
See it in action
A few snapshots from the app — from the home hub to the sound library, the mixer, the tone generator, breathing and affirmations, and the Learn hub.
