Wear your Apple Watch to bed. That's it.
Sleep++ takes advantage of the motion and health monitoring capabilities of your Apple Watch to measure both the duration and quality of your sleep.
It all happens automatically, so you can drift off without worrying about tracking. You don't even need to install anything on your Watch: it shares what it measures with Sleep++ on your iPhone.
Data should be useful
Better understanding your sleep means you can make smarter decisions about your routines, both day and night.
Review your whole week, dive into a single night, or check your Readiness Score, all from your iPhone.
Every night, stage by stage
Sleep++ tracks periods of REM, core, and deep sleep, and draws them in easy-to-understand charts that are still dense with information.
Alongside your sleep stages, it charts your heart rate, respiratory rate, and blood oxygen levels through the night.*

Know how ready you are for the day
Your Readiness Score draws on your heart rate variability, resting heart rate, activity, and sleep to show how well you've recovered from the day before.
It's a helpful guide when planning your day, and a week of scores shows how your nights add up.

Integrated with Apple Health
Sleep++ works with Apple Health to give it a safe and private way to read your sleep data. That data is used for automatic sleep tracking, and you can choose to have Sleep++ save each night to Apple Health too.
Your sleep data is stored on your device. It's never sent to us, and never shared with a third party.
