Sometra: Sleep Tracker

Sometra tracks your sleep the way it should be tracked: entirely on your phone, with nothing ever sent anywhere else.

While you sleep, Sometra listens for snoring, talking, coughing, and other sounds, and reads your phone's motion sensor to gauge how restless your night was — then turns it into a clear sleep score and a night-by-night history you can actually learn from.

WAKE UP BETTER
• Smart Alarm — wakes you during a lighter stage of sleep within your chosen window, instead of jolting you out of deep sleep
• Sunrise Alarm — gradually brightens your screen and fades in a sound of your choice before your alarm, for a gentler wake-up
• Fixed Alarm — for when you just need to be up at an exact time

UNDERSTAND YOUR NIGHTS
• Snore, talk, cough, and noise detection with playback, so you can hear exactly what happened
• Trends across weeks and months: consistency, sleep debt, best and worst conditions, and what actually helps you sleep better
• A Journal for notes and tags — see what caffeine, exercise, or a stressful day actually does to your sleep

FALL ASLEEP EASIER
• Built-in wind-down sounds — rain, ocean, wind, fireplace, thunderstorm, crickets, and a running stream
• A guided breathing exercise and bedtime ritual to help you settle in

BUILT ON PRIVACY, NOT AROUND IT
Sometra has no account, no login, and no server. Every recording, every score, every setting stays on your device — nothing is ever uploaded, shared, or sold. Sound classification runs entirely on-device too. There are no ads, no analytics, and no third-party trackers of any kind.

Sometra is free to use. An optional Pro subscription unlocks deeper insights and extra features, billed through Google Play — we never see your payment details.

Sleep tracking that respects your privacy as much as your sleep.
