Free to download · iPhone · No wearable, no ring, no account required to start.
The problem
You spend eight hours in the dark — and still wake up exhausted, with no idea why. Is it a breathing stutter? A noise you don't remember? Snoring? A night quietly broken into pieces? So you change things at random and hope for a miracle. The cause is hiding in the hours you sleep right through.
SleepTrace makes that night visible: what happened, when, and the one thing worth changing tonight — instead of guessing.
The difference
Eight hours in bed — and no real idea what happened in them.
One night of audio, turned into a clear, honest picture.
Features
Six tools, one app. Tap through what SleepTrace hands you every morning.
How it works
Set it on the nightstand and start. SleepTrace listens, analyses on your device, and hands you one insight that actually explains your night.
Your iPhone records the night through its microphone. No watch, no band, no chest strap — the phone on your nightstand is the entire setup.
On-device AI turns the sound into a visual map of your night and reads each sleep phase with our own science-backed model — every 30 seconds.
In the morning you get the picture: your phases, the sounds from the night, and the one pattern worth knowing — not twelve metrics you have to decode.
A wrist sensor can tell that you moved. It can't hear the room. SleepTrace listens to the one signal a wearable physically misses — sound: your breathing, snoring, pauses and the space around you. Every 30 seconds it isolates your breath from background noise with high-resolution acoustic analysis — catching the subtle stutter a motion sensor is simply blind to.
Your iPhone captures the night from the nightstand — no wearable.
Every second of sound becomes a clear visual map of your night.
A science-backed model we built reads each phase — on your iPhone, every 30 seconds.
You measure training to the watt. Macros to the gram. Sleep — the recovery that powers all of it — you still leave to a guess.
For those who treat recovery as a science, not a side effect.
Keep your Oura, Whoop or Apple Watch — they're great at the wrist. SleepTrace adds the one dimension they physically can't capture: sound and breathing. That's where the reason behind a rough night actually lives.
It tells you that.
A recovery score that says the night was rough — but never why, and never what to change.
Readiness 61 — and silenceIt tells you why.
The actual sounds and breathing behind the bad night — the 03:40 your ring never heard.

Snoring and breathing pauses can go unnoticed for years — and they're worth taking seriously. Here's how SleepTrace turns them into something you can actually act on.
Snoring and breathing pauses happen while you're asleep — so you never notice them.
SleepTrace records and measures the whole night — every sound, second by second.
Play back the actual clips — the snore at 02:14, the breathing pause at 03:40.
Walk into the appointment with real recordings — not a vague worry.
SleepTrace is a wellness app, not a medical device. It doesn't diagnose — it surfaces signals and recordings you can review with a qualified professional.
Privacy isn't a footnote: your sleep sounds are none of our business. Everything runs on your iPhone — it even works in airplane mode.
Wake up clearer
Being torn out of deep sleep is half of why mornings feel rough. SleepTrace's smart alarm finds the lightest moment inside your wake-up window and lifts you out gently — the difference between groggy and ready.
It's a small change with an outsized effect: the same alarm, timed to how you're actually sleeping.
Do you often wake around 3–4 a.m. — for no reason you can name?
YesDo you wake up feeling like you barely slept — even after a full eight hours?
YesHas someone told you that you snore — and you had no idea it was happening?
YesSleepTrace doesn't answer with a score and a shrug. It records the night and shows you the evidence — so the answer stops being a guess.

PremiumA two-second check after waking reveals how your sleep really affects how you feel.
Recommendations grounded in sleep medicine and CBT-I — small, specific steps, not vague advice.
