Dozer: Sleep Tracker

Dozer turns your night into a morning you can actually read — with a watch or ring, or with nothing but your iPhone.

Apple Health shows the raw numbers. Dozer is the layer on top: a plain-language morning report, your sleep debt over time, an energy forecast for the day, snore detection with playback (Dozer+), streaks that never guilt you, and a silent wrist alarm that picks a light-sleep moment before your set time — you wake gently, and nobody else in the bed wakes at all.

NO WEARABLE? DOZER STILL WORKS
• Dozer builds an estimated night from what your iPhone already noticed — the in-bed record your Apple sleep schedule keeps, an overnight Night Listening session, or both
• One tap confirms the window, or you adjust it yourself — you stay the authority on your own night
• Time in bed, your morning check-in, your tags and what the night sounded like, all on the same card
• Estimated nights appear in Trends as lighter bars and count toward bedtime consistency
• No sleep score, sleep stages or heart rate on an estimated night — those come from a sensor on your body, and Dozer doesn't invent them. Sleep debt, streaks and the energy curve are built on the score, so they wait for a tracker too
• If a tracker later reports the same night, it replaces the estimate

A tracker adds more: any watch, ring or band that saves sleep to Apple Health — Apple Watch, Oura, Whoop, Withings, Garmin, Polar, Amazfit — brings sleep stages, overnight heart rate and HRV, and a sleep score. (Fitbit and Samsung watches keep sleep in their own apps and don't write it to Apple Health. The silent wrist alarm is the one part that needs an Apple Watch.)

YOUR MORNING, EXPLAINED
• A sleep score and a warm one-line read of the night (wearable nights)
• Sleep debt, tracked over a rolling two weeks
• Today's energy curve, built from last night (Dozer+)
• Daytime naps counted as their own sleep, with their own detail
• A dream note, one tap from the night it belongs to — free, kept on your iPhone, and never part of an export or a feedback message

NIGHTS, HANDLED
• Night Listening counts snoring sounds — analyzed on your iPhone, and the audio never leaves it (results with Dozer+)
• Sound clips of the snoring and talking it hears, kept on your phone and removed on the schedule you pick in Settings (7, 14, 30, or 90 days) — switch them off any time
• Wind-down soundscapes that fade out on their own

A GENTLER WAKE-UP
• A silent tap on your wrist, timed to a light-sleep moment in the window before your set time — no sound, no waking your partner
• A recurring schedule that re-arms itself — set it once (Dozer+)

PRIVATE BY ARCHITECTURE
No accounts. No analytics. No ads. Your sleep is processed on your devices and stays there — it only ever leaves if you choose to share it yourself, whether attaching a night to a feedback message or sharing a screenshot.

Dozer+ is one purchase, yours forever — no subscription required.
