Your sleep over time
Average sleep and typical bedtime over 7, 30 or 90 days, or all of your history.
How it works
How does Wonderwake track sleep on iPhone?
Wonderwake builds your sleep history from what you already have. If you wear an Apple Watch or a sleep ring, its sleep data reaches Wonderwake through Apple Health. If you don’t wear anything, your iPhone can estimate when you fell asleep and woke up on its own.
- Apple Watch. Sleep times and sleep stages from the Sleep app.
- Oura, WHOOP, Garmin and Ultrahuman. Turn on sharing with Apple Health in the device’s own app, and their nights appear in Wonderwake.
- Just your iPhone. No watch needed. You get your sleep times and duration, without stages.
When more than one source recorded the same night, Wonderwake uses the most detailed one. And if your watch syncs late in the morning, that night is completed instead of counted twice.
Sleep debt
What is sleep debt, and how is it worked out?
Sleep debt is the gap between the sleep you got and the sleep you need. Wonderwake compares your last five sleeps with your sleep goal and adds up the difference.
Tap Sleep debt to see those nights one by one: which ones added to your debt and which ones paid some of it back.
Your sleep goal is yours to set, and Wonderwake can suggest one from your own history. The same goal is used across the app, including for Sleep Gate, your suggested bedtime for tonight.
Sleep stages
Can it show REM and deep sleep?
Yes, when your watch or ring records them. Last sleep shows a timeline of Awake, Light, Deep and REM sleep from the device that recorded the most detail that night.
Stages from two different devices are never mixed, and time with no data is marked as No data instead of being guessed. Without a wearable you still see your sleep times and duration.
Fix a night that was recorded wrong
Were you reading in bed, or did your watch run out of battery? Edit the start and end of your last sleep. Your sleep debt and tonight’s bedtime suggestion update right away.
More than sleep
What else does your sleep data unlock?
Your nights power the rest of Wonderwake. They set Sleep Gate, and after about five nights they reveal your chronotype in Rhythm, along with when your energy is likely to peak and dip.
Rhythm also shows today’s steps, distance and recent workouts from Apple Health, so a busy day sits right next to the night that followed.
Your sleep data stays on your iPhone.
