Todo lo necesario!
Graba ronquidos y tiene la opción de que se guarden únicamente los que se detectan. Tiene despertador incluido opcional y el resumen de la noche es completo y me ha ayudado a dar seguimiento a mis hábitos de sueño

STEP 1 / 5
Works with what you already wear
Connect once. Get your sleep stages.
Snore Timeline estimates your stages from breathing audio on its own. Connect a wearable through Apple Health and it pulls in that device's sleep stages, heart rate, HRV, blood oxygen, and temperature too, importing up to 2 years of history the first time.

More Than Snores
A number alone tells you nothing. Snore Timeline reads each overnight vital against your own baseline and says what it means in plain language, so you learn why it matters, not just what it was.
0br/min
Steady
Breathing Rate
Calm and even. A steady rate through the night is the signature of relaxed, undisturbed sleep. Spikes can flag stress or disruption.
0bpm
Good
Heart Rate
Settled low. Your heart drops to its resting floor as you sleep. The lower it goes below your average, the more your body recovered.
0ms
Good
HRV
Above your average. Wider gaps between beats mean your nervous system recharged overnight rather than running under strain.

Blood Oxygen
Well supplied. Holding at or above 95 percent means your breathing kept your blood richly oxygenated through the night.

Wrist Temperature
Near baseline. Skin temperature drifts with illness, cycle, and strain, so sitting close to your norm is a quiet all-clear.

Audio-Based Estimation
How We Estimate Your Sleep Stages
Using only your phone's microphone, Snore Timeline estimates when you're in light sleep, deep sleep, or REM based on published research into breathing regularity during sleep. And when your breathing is too quiet to hear, it doesn't guess — those calm stretches are labeled Silence and counted as restful sleep.
Listen to Your Breathing
Continuous audio capture via your phone's microphone picks up breathing rate, regularity, and snoring patterns throughout the night
Establish Your Baseline
After ~15 minutes the algorithm learns your personal breathing rate and regularity baseline, adapting thresholds to your unique patterns
Analyze Breath Regularity
Research-based thresholds analyze regularity and variance. Steady, low-variance breathing suggests deep sleep; irregular patterns with high variance indicate REM
Adapt Through the Night
Time-aware logic accounts for natural sleep architecture. Deep sleep peaks early in the night, REM increases toward morning
Honest About Quiet Sleepers
Because everything comes from audio alone, very soft breathing — or a fan masking it — can be inaudible. Instead of guessing a stage, those undisturbed stretches are labeled Silence and credited as restful sleep. A quiet night is the goal, after all

Beyond Snore Tracking
Detect When You Stop Breathing
AI-Powered Analysis
How We Detect Disruptions
In addition to snore detection, our algorithm identifies moments when you stop breathing for 10+ seconds—helping you spot patterns worth discussing with a doctor.
Baseline Observation
Monitors audible breathing for at least one minute to establish accurate baseline patterns
Silence Detection
AI identifies extended quiet periods lasting 10+ seconds—a key indicator of breathing disruptions
Recovery Recognition
Detects loud abrupt snoring, gasps, coughs, or breathing sounds that follow the silent period
Timeline Marking
Places markers at exact timestamps, creating a visual map of disruptions
Apple Watch
Snore Nudges and a Smart Alarm on Your Wrist
Most snore trackers just report in the morning. With an Apple Watch, Snore Timeline nudges you when you snore and wakes you when you are sleeping lightly.
Snore Nudge
A tap on the wrist when you snore
When snoring is detected live, your watch taps your wrist, just enough to prompt a position change without waking you. It works with your iPhone locked and the watch app closed.
Paces itself: quick retries while snoring continues, then backs off, and stops for the night when nudges are not working
Scores every nudge in the morning, from "Stopped snoring for 3 min" to "Quiet until morning"
Shows the snoring rate five minutes before and after each tap, so you learn whether position changes work for you
Give the alarm a window of 15, 30, or 45 minutes and it rings when it finds you sleeping lightly, instead of pulling you out of deep sleep at the exact minute.
Or wake with no sound at all: turn the alarm off and your Apple Watch taps your wrist instead, so your partner sleeps through it
Rings at your set time no matter what, so you can never oversleep
Fades in gently, and tells you in the morning how many minutes early it woke you
What makes Snore Timeline different from other snore tracking apps?
Snore Timeline keeps the full night's audio and lays it on an interactive timeline you can scrub through and tap to hear. Recording is continuous, not sampled, so a quiet hour reads as a quiet hour. The app tags coughs, gasps, sleep talking, and breathing pauses as their own categories, and groups consecutive sounds into episodes you can play back.
Sleep stage data merges in from Apple Watch, Oura Ring, Whoop, Garmin, and Ultrahuman. Detection runs on your phone. No cloud, no account, no subscription.
What is the difference between the sleep score and the recovery score?
The sleep score rates how you slept, from your recording: duration, efficiency, sleep stages, snoring, and bedtime regularity on a 0 to 100 scale. The recovery score reads how your body responded overnight, from your Apple Watch vitals: heart rate variability, resting heart rate, breathing rate, blood oxygen, wrist temperature, and time asleep, each compared to your own baseline.
The morning summary blends both into one plain-language status, like "Well Recovered." The recovery score needs a wearable that writes to Apple Health; the sleep score works from audio alone. Both are personal-insight scores, not medical assessments.
Can it wake me without an alarm sound, so my partner keeps sleeping?
Yes, with an Apple Watch. Turn the alarm sound off and turn on the wrist nudge, and the alarm reaches you as a steady rhythm of taps on your wrist instead of noise: two waves of taps over about six minutes, so a deep sleeper gets a second chance. Your partner sleeps through it.
It pairs with the smart alarm, so the taps can arrive during light sleep rather than at a fixed minute, and dismissing the notification on your watch stops the alarm and the recording together. You can also run taps alongside the sound if you want both.
No. Snore Timeline is completely free with no subscription required. All features are included: breathing disruption detection, episode grouping, nightly summaries, and data export—no hidden costs or in-app purchases.
Is my data private?
Absolutely. All audio processing happens entirely on your iPhone—no cloud uploads, no external servers, no accounts required. Your recordings stay on your device and only you have access to them. You can export data to share with doctors while maintaining complete privacy.
Yes, Snore Timeline detects breathing pauses by analyzing your sleep audio. It identifies extended silent periods (10+ seconds) followed by gasps or recovery sounds. The app marks these breathing disruptions on your timeline so you can see patterns. Note: This is audio analysis only, not a medical device. Breathing pauses may be worth discussing with a healthcare professional.
Snore Timeline uses Apple's proven sound classification technology to continuously analyze your audio in real-time throughout the night. Detection starts immediately with no calibration or setup needed. The app identifies snoring, gasps, coughs, breathing, and sleep talking by analyzing both the sound patterns and frequency characteristics of each audio segment. All processing happens entirely on your device for complete privacy.
Yes! Snore Timeline supports Bluetooth audio devices including AirPods, making it easy to record throughout the night without draining your phone's battery.
You can export the entire night's audio as a single file, or bulk download all your snoring episodes at once. For a richer export, tap the download icon to open the Export Report sheet — pick a date range and include summaries, sleep phases, events, biometrics, and (optionally) audio. The report exports as CSV plus any audio you chose to bundle.
