Outer ring
Slept
Hours asleep against your nightly goal. Aim for 8 and sleep 7h 22m? The ring shows exactly how much night you left on the table.
Sleep & Snoring Tracker
Rings for sleep.
Drowse turns every night into three rings of how long you slept, how consistent you were, and how efficient your night was.

The SleepRings
Three rings. One honest number.
Every metric is measured against your goals — not a population average. Drowse reads your night from Apple Health, compares it to the targets you set, and draws the result.
Middle ring
Regularity
How close your bedtime and wake-up landed to the schedule you chose. Consistency is the quiet superpower of good sleep — this ring makes it visible.
Inner ring
Efficiency
The share of time in bed you actually spent asleep. Tossing, scrolling, staring at the ceiling — it all shows up here, without judgment.
Every morning
Wake up to a night you can read.
Open Drowse and last night is already there — rings drawn, score computed, no spelunking through charts. Swipe back through a year of nights, or scan the weekly strip of mini rings to spot the pattern.
- Up to a year of history for you to track trends.
- A weekly ring strip and monthly calendar to jump to any night.
- Slept, regularity, efficiency summarized under every session.
Advanced Snore Detection
It listens, so you don't have to ask.
Press start, put your iPhone on charge by the bed, and Drowse listens for possible snoring with private on-device processing. By morning, you can review detected clips, duration, episodes, and an overnight snoring level.

Analysis happens entirely on your iPhone. Drowse keeps no continuous overnight recording; short detected clips stay privately on your iPhone for seven nights and are never uploaded.
Your score, your rules
No two sleepers are alike.
A shift worker's great night looks nothing like a new parent's. Drowse lets you weight what matters — pile onto hours slept, ease off regularity, or account for detected snoring after a sufficiently covered night. The score becomes a mirror of your priorities, not someone else's rubric.
- Five weight sliders — hours, regularity, efficiency, duration snored, and phase ratio.
- Goals for every metric, from bedtime tolerance to efficiency thresholds.
- Synced through iCloud, so your definition of a good night follows you.

✦ Based on these weightages, your Drowse SleepScore primarily relies on hours slept, time spent sleeping while in bed, and the quality of your sleep phases.
Nights, handled
One tab runs the whole night.
Set a wake time, choose whether Drowse should wake you, start snore tracking — done. Real alarms through Apple's AlarmKit, wind-down reminders before bed, and automatic sleep tracking when you wear your Apple Watch.
- Real wake alarms with custom alarm sounds.
- Track with Apple Watch or any compatible wearable — rings fill themselves.
- Wind-down alerts to nudge you toward bedtime before you doomscroll past it.
Widgets
Your nights, on your Home Screen.
Widgets keep sleep in view without opening the app, from last night's rings to the week ahead, a sleep map, and a bedtime countdown that starts tracking with one tap.
Sleep Map
A month of nights, mapped cell by cell.
Built for the ecosystem
Feels native, because it is.
No web views, no wrappers. Drowse is built on the frameworks Apple ships — so every permission is explicit and every interaction feels like it belongs on your iPhone.
Apple Health keeps your sleep history private.
Privacy
Your nights stay on your iPhone.
A sleep tracker hears you at your most unguarded. That's exactly why Drowse was designed so it never has to phone home.
Audio never leaves the device
Snore analysis runs with private on-device processing. No continuous overnight recording is kept or uploaded; only short detected clips are stored locally for seven nights.
Health data stays in Health
Drowse reads sleep from Apple Health with your permission and writes nothing back to the cloud. Your history lives on your phone.
Sign in with Apple only
No passwords, no ad tech. Your app identity is your Apple ID, and only your preferences sync through your own iCloud.
Drowse for iOS
Close your rings with your eyes closed.
Drowse is available on the App Store. Download it on iPhone and start making sense of every night.
