Landmark / Sleep
See how you slept last night.
Your sleep, heart and breathing readings from Apple Health, together on one screen. See last night against what is usual for you.
No score, no account and nothing to log. Landmark Sleep is an iPhone app.
The last night
Five readings. One night.
Sleep time, lowest heart rate, HRV, blood oxygen and breathing rate sit together at the top. Each ring shows the recorded value and where it sits against your own recent nights.
- Your usualAfter three earlier nights with a reading, a white mark shows your usual. The label says Usual, Higher or Lower.
- No invented dataWhen Apple Health has no reading, the ring says No data. Landmark Sleep never substitutes a sample night for yours.
- The night in timeSee when you fell asleep, when you woke and how long you spent in bed.
Sleep stages
The shape of the night, on one timeline.
Awake, REM, Core and Deep appear on the same time axis, with totals and the share of sleep in each stage. If your source does not record stages, the screen says so and shows asleep and awake instead.
- More from your WatchWhen recorded, a lower card adds resting heart rate, wrist temperature, lowest blood oxygen and breathing disturbances.
- Only last nightThe free app focuses on the newest night. It does not offer a score, history browser or trends.
Inside the app
See the screen for yourself.
The app's own App Store frames show its Last night screen, stage timeline and on-device privacy.
Apple Health
Reads Apple Health. Stays on your iPhone.
Landmark Sleep asks for read access to the night data you allow. It does not write to Apple Health or send your readings to a Landmark server.
Sleep can come from Apple Watch or a sleep app that saves to Apple Health. Heart, HRV, blood oxygen and breathing readings need an Apple Watch worn to sleep.
You choose which types to share in Apple's permission sheet and can change access in Apple Health.
There is no Landmark account, server or in-app analytics. Calculations run on your iPhone.
