Snore Recorder for good night

Plenty of apps will tell you how much you snored.
Snore Recorder goes one step further — it records what your body was doing at the moment each snore happened.


■ Your heart rate during each snore

Wear an Apple Watch to sleep and the app works out how far your heart rate rose around each snoring episode and how long it took to settle. Where there is no heart data, nothing is shown — no estimates are filled in. Inventing numbers is the worst thing you can do with health data.


■ Stretches that look like paused breathing

The app looks for a specific pattern: snoring stops, then restarts louder than usual. Each one is listed with its time and how long the quiet stretch lasted. If your heart rate rose or your blood oxygen dipped at the same moment, that is shown alongside. When such stretches are observed, guidance to see a specialist appears with them.


■ Laid over your sleep stages

Snoring is drawn on top of the core, deep and REM stages your Watch recorded. See which stage the snoring clustered in and what your sleep efficiency was, on one screen.


■ Nights with alcohol, tobacco or medication — and nights without

Note the evening's drinks, cigarettes and medication before you sleep, and the app splits your history into those nights and the rest. Anything without enough nights behind it is hidden entirely — a conclusion drawn from three nights is worse than no conclusion.


■ Your whole night is never recorded

Only the last 25 seconds are ever held in memory. When a snore is confirmed, just that stretch is written to disk. Storage never balloons into hundreds of megabytes, and audio never leaves your device. You choose how long clips are kept.


■ Apple Watch companion

The Watch app collects heart rate through the night and sends it to your iPhone. Without a Watch, snore detection and paused-breathing observation still work.
