I sleep 7.5 hours but was only getting 45 minutes of deep sleep. SleepTrace showed me exactly that — and I fixed it within two weeks.

Do I need a wearable device to use SleepTrace?
No wearable needed. SleepTrace uses your iPhone’s built-in microphone combined with advanced machine learning to analyze your sleep. Just place your iPhone beside your bed and let SleepTrace do the work overnight.
How accurate is the sleep phase detection?
SleepTrace uses Mel-spectrogram analysis and CoreML to detect breathing patterns, movement sounds, and snoring. Our algorithm identifies light, deep, and REM sleep phases with high confidence. Results align closely with polysomnography studies for consumer-grade sleep tracking.
Can SleepTrace detect sleep apnea?
SleepTrace can detect possible signs of sleep apnea and irregular breathing events. This is not a medical diagnosis — if you notice consistent alerts, we recommend consulting a healthcare professional. SleepTrace is not a medical device.
Will the recording use a lot of battery or storage?
SleepTrace is highly optimized for overnight use. The app uses minimal battery thanks to smart background processing, and audio is analyzed locally on your device. Only sleep event clips are saved, not full night recordings by default.
