Understand your sleep, then improve it
The Sleep Coach reads your sleep from Apple Health on iPhone or Health Connect on Android and turns it into a simple score, your sleep stages, and the everyday habits that affect them.
Connect once, read-only
Tap Connect Apple Health (iPhone) or Connect Health Connect (Android) and allow sleep access. The Sleep Coach reads sleep only (time asleep and awake, deep, REM, light and time in bed) and never writes anything back. Until you connect, it shows clearly labelled sample data so you can see how it works.
Your sleep score
Each night gets a score from 0 to 100, rated Great (85+), Good (70+) or Fair (50+). It weighs how long you slept (seven to nine hours is ideal), how much was deep and REM sleep, how efficiently you slept, and how consistent your schedule is.
Sleep stages
See how the night split between Awake, REM, Core and Deep sleep, with the share of each.
What affects your sleep
Sleep factors connect your night to your day, using what you’ve logged in the app: hydration, exercise, dinner timing and caffeine. A food and sleep card and a seven-day history help you spot patterns.
AI Sleep Insight (Premium)
With Premium you get a personalized summary of your sleep and what’s contributing to it, plus a “Try this tonight” suggestion you can add to your routine. Sleep summaries are sent to Google Gemini only after you give permission, and are never used for advertising.
Build better sleep habits
Join the 14-Day Sleep Routine challenge (in bed before 11 pm), and wind down with a sleep body scan or breathing session in Meditation Pal.
The Sleep Coach offers general wellness information. If you have ongoing sleep problems, talk to a doctor.
Sleep coach questions
Is the sleep tracker free?
Yes. Connecting Apple Health or Health Connect, your sleep score, stages, sleep factors and history are free. The AI Sleep Insight is Premium.
Do I need a smartwatch?
The Sleep Coach uses the sleep data already in Apple Health or Health Connect, which can come from a watch, a sleep-tracking app or your phone. The more detailed that data, the more detailed your stages.
Does AI Wellness Pal write to Apple Health or Health Connect?
No. It only reads your sleep data, with your permission, and you can disconnect at any time in your phone’s settings.
How is the sleep score calculated?
From four things: duration (seven to nine hours is ideal), deep and REM sleep, sleep efficiency and schedule consistency, combined into a 0 to 100 score.
