Wind down
Your daily plan tells you when to start. A story, a soundscape and a fading timer take it from there.
Sleep cycle tracker & relaxation
Your best sleep
starts tonight.
Harmony tracks your sleep cycles, scores your rest, and builds a nightly wind-down plan — then lulls you to sleep with hand-crafted soundscapes, stories and white noise. Even offline.

One honest number for how well you rested — with recovery analysis that tells you what tonight should look like.
Your daily plan
Sleep debt, your energy peak, ideal bedtime and when to start winding down — a personal plan, updated every day.
Custom soundscapes
Layer campfire over rain, thunder over the sea. Mix your own ambient world, loop it, and save it for tonight.
Offline listening
Download your favourite sounds, stories and playlists. No signal in the cabin? Your sleep travels with you.
Mood & wind-down
A gentle daily reflection and mood tracker, plus a wind-down routine that starts before your ideal bedtime.

Every night broken into the stages that matter, with clear percentages and times.
Recovery analysis

Daily plan
A plan that puts you to sleep on time

Soundscapes
A library of calm, always with you
Ambient sounds, relaxation music, sleep stories and noise colours — brown, white and pink — crafted to quiet your mind.
Build your own world of sound
Pick from campfire, underwater, frogs croaking, birds at dawn, thunder storms and more — then layer them into a mix that's entirely yours.

- Brown, white & pink noise, and natural sounds
The science of sound
Three noises, three jobs
Not all sound is equal. Each noise colour works on your brain differently — here's how to pick yours.
Brown noise
For deep sleep
Low and rumbling, like steady rainfall or a distant waterfall. Brown noise masks low-frequency disturbances — snoring, traffic hum — so your deep sleep stays uninterrupted.
Learn moreWhite noise
To fall asleep faster
An even blanket of sound that covers the little noises that keep your mind alert. Perfect for light sleepers, shared walls and babies who need the room to feel still.
Learn morePink noise
To improve sleep quality
Softer than white noise, deeper than silence — like ocean waves on a quiet beach. Pink noise gently stabilizes your sleep so you wake feeling genuinely restored.

Mix it your way
Start with a single sound, then layer others on top — every mix is saved for your next night.

Echoes of Tranquility
Pink noise washed over ocean waves and starlit beaches — for deeper, steadier sleep.
Contemplative Spaces
Ambient background for focus, study and quiet afternoons — consistent sound, zero distraction.
Mood & habits
Small rituals, better nights
Harmony keeps your streak alive with daily reflections and little rewards — gentle motivation that makes good sleep a habit.
Mood tracker & daily reflection
A two-minute check-in each day. Over time, Harmony shows how your mood and your sleep move together — so you can change what matters.
Collect a little calm, daily
Every day you use Harmony, you earn a keepsake for your collection — a gentle nudge to return to your ritual, night after night.
AI sleep assistant
A calm companion when your mind won't quiet down
Harmony's AI assistant is trained for one thing: helping you relax. Ask for a guided meditation, a breathing exercise, a bedtime story or the perfect sound for tonight — and it sets everything up for you.
Guided meditations
Personal, spoken calm when you need it most.
Bedtime stories
Slow, gentle tales that fade into dreams.
Breathing exercises
Simple patterns that switch your body to rest mode.
Smart sound picks
The right noise or playlist for how you feel tonight.
My mind won't stop racing tonight…
Let's slow it down together. Start with a slow breath in for four counts — I'll guide you through a short meditation.
That helped. Can you play something calm too?
Of course — starting Lunar Glow with a 30-minute fade-out. Sleep well. 🌙

Questions
Everything else you're wondering
Yes — Harmony is free to download on the App Store. A subscription unlocks the entire library of sounds and stories, unlimited revival tones and exclusive mood reports. You can choose monthly, yearly or a one-time lifetime purchase.
Absolutely. Download any sounds, stories or playlists and take them anywhere — a cabin, a plane, or a bedroom with patchy Wi-Fi. Your sleep ritual never depends on a signal.
Harmony tracks your sleep cycles and produces a daily sleep score with a breakdown of deep, light, REM and awake time. It also syncs with Apple Health so your sleep data lives alongside the rest of your health information.
Natural sounds like rain, thunder, ocean waves and campfire, plus brown, white and pink noise — all carefully engineered for sleep. You can also mix sounds together and loop them for the perfect custom soundscape.
Set a timer and Harmony will gently fade the audio out as you drift off — no abrupt endings, no battery drain from all-night playback.
Of course. Subscriptions are managed through your Apple ID, so you can change or cancel in a few taps. No emails to support, no dark patterns.
Tonight could be the night
you sleep beautifully.
