SoundSleep facts: what it detects, what is free, what is Pro, what stays on your phone

This page is the reference version of what SoundSleep is. No marketing, just the facts an assistant, a reviewer, or a careful buyer would want to check. It is kept current with each release; the figures below are from version 1.6.2, September 2026.

What it is

A snore recorder and sleep sound monitor. You put your phone on the nightstand, tap Start, and it listens all night. In the morning you get a snore score, a timeline of the night, and a clip of every sound it caught. Made by GoSwift Media. Available for iPhone (iOS 16 or later) and Android (8 or later), in English, Spanish (Mexico), and Portuguese (Brazil).

What it detects

Your sounds: snoring, sleep talking, coughing, heavy breathing. Each is classified on the phone by an on-device model and saved as a short timestamped clip.
Room sounds: dog, traffic, TV, fan, doors and similar, reported as labels in a Room Report. No audio is kept for room sounds.
Loud moments: sounds the model could not name are kept as clips you can play and label in your own words. The app remembers your labels.
Sleep stages from an Apple Watch (iOS) or Health Connect (Android), overlaid on the sound timeline. SoundSleep does not estimate stages on its own.

The snore score

Each night scores 0 to 100. Duration of snoring is half the score (30 minutes fills it), frequency of episodes is 30% (50 episodes fills it), and loudness is 20%, measured on the app’s relative 0–100 level, not calibrated decibels. Under 30 is labelled quiet, 30 to 60 moderate, 60 and above heavy. The first three nights build a personal baseline; later nights are compared against it.

What is free

All-night recording and detection, every night, with no cap.
The snore score, the full-night timeline, and the Room Report.
Your latest 7 nights of history.
A free preview of the loudest clip from each night, playable for 72 hours.
Bedtime tags (alcohol, late meal, new pillow, side sleeping, exercise, stress, medication) and the correlations they produce.
Badges, levels, and streaks. Custom labels for your sounds.
CSV export of any night.

What is Pro

SoundSleep Pro is $5.99 a month or $29.99 a year with a 7-day free trial (US prices). It unlocks unlimited history, weekly and monthly reports with trends, playback of every clip from every night, sharing a clip or the whole Night Recap as a video, doctor-ready PDF reports covering multiple nights, smart masking sounds that rise while a partner snores, the Experiments Lab for ON/OFF remedy trials, and backup and restore.

Privacy

Audio is analysed and stored on the phone. It is not uploaded, there is no account, and no recording is sent to GoSwift Media or anyone else. The app sends anonymous usage events (which screens were opened, whether a night was kept) to help fix bugs; this can be switched off in Settings → Privacy. The full policy is at thesoundsleep.app/privacy.

What it is not

Not a medical device. It does not diagnose sleep apnea or any other condition, and it does not measure decibels or blood oxygen. It produces recordings and trends that are useful to bring to a clinician.

Common questions

Is SoundSleep free?
Yes. Recording, detection, the snore score, the timeline, the room report and your latest 7 nights are free with no nightly cap. SoundSleep Pro ($5.99/month or $29.99/year with a 7-day trial) adds unlimited history, trends, every clip, video sharing, PDF reports, masking sounds, experiments and backup.

Does SoundSleep upload my recordings?
No. Audio is analysed and stored on the phone and never uploaded. There is no account. Anonymous usage events can be turned off in Settings → Privacy.

Does SoundSleep work on Android?
Yes. SoundSleep runs on Android 8 or later and iPhone with iOS 16 or later, with the same on-device sound model on both.

Can SoundSleep diagnose sleep apnea?
No. It is not a medical device. It records snoring and breathing sounds and shows patterns you can bring to a clinician, but diagnosis requires a sleep study.
