Your Apple Watch tracks sleep stages, heart rate, heart rate variability (HRV), blood oxygen, ECG, temperature, sleep apnea, breathing disturbances, and more—but what does all that data mean? More importantly, what do you actually do to get more shut eye?
If your Apple Watch detects sleep apnea, get medical care covered by insurance.
Empirical Sleep distills your Apple Watch health data into one simple sleep score, then suggests actions to help you improve your sleep duration, onset, and quality. Unlike other free sleep trackers for Apple Watch, we're focused not just on more data, but helping you actually sleep better and get more shuteye.
** Sleep score **
Our sleep score auto combines everything into one simple number, including the percentage of time you spend in REM sleep, deep sleep, your heart rate, HRV, and oxygen during sleep, your sleep duration, and how long it took you to fall asleep.
On the checkup screen, you can monitor your health stats against other users of Empirical Sleep and medical norms to understand where you're above, below, and right around the average.
** Take action to improve your sleep **
The goal of all this health monitoring isn't just tracking—it's to act and get better shuteye. The goals tab suggests a comprehensive plan to improve your sleep, including assessing sleep hygiene and risk of sleep apnea.
** Monitor your risk of sleep apnea **
1 in 8 adults have sleep apnea. What's more, 80% of people with sleep apnea don't realize they have it. On the checkup screen, assess your risk of sleep apnea using a medically-validated questionnaire. If you receive an Apple Watch sleep apnea alert, book a priority appointment directly with a doctor for sleep apnea testing and treatment.
** Native Apple Watch app **
View your sleep duration, onset, quality, and stages (REM/deep/core/awake) directly on your watch using our native Apple Watch sleep app.
** Watch face & iPhone lock screen widgets **
Display your sleep stages, sleep duration, onset, and quality directly on your watch face or your iPhone's lock screen, using the new widgets introduced in iOS 16 and watchOS 9.
** Compatible, integrated with health, and free with an optional subscription **
Empirical Sleep is compatible with Apple Watch Series 3 and above. It integrates with the Health app to auto track your sleep segments, heart rate, HRV, blood oxygen (SpO2), steps, sleep stages, breathing disturbances, sleep apnea alerts, and activity. Empirical Sleep is a free app to download, with an optional paid subscription.
** About Empirical Health **
Empirical Health's mission is to build proactive healthcare. Today's healthcare system spends $1.1T reacting to chronic conditions and only a tenth of that on prevention. Our goal is to flip that and build a new type of primary care that's preventive rather than reactive, starting with sleep.
Please seek a doctor’s advice in addition to using this app and before making any medical decisions. If you need a doctor, you book a video visit directly through this app. We accept most major health insurance.
