Empirical Sleep Tracker 2.11

Your Apple Watch is capable of tracking a wide range of health data including sleep stages, heart rate, HRV, blood oxygen levels, ECG, and temperature. But what do all these numbers actually mean? More importantly, how can you use this information to improve your sleep? That's where Empirical Sleep comes in.

Empirical Sleep takes the data from your Apple Watch and distills it into a simple sleep score. This score combines factors such as the time spent in REM sleep and deep sleep, heart rate, HRV, oxygen levels during sleep, sleep duration, and sleep onset time. It provides you with a clear and concise number that reflects the overall quality of your sleep.

But Empirical Sleep doesn't stop at just giving you a score. It goes a step further by offering actionable suggestions to help you improve your sleep duration, onset, and quality. Unlike other free sleep trackers for Apple Watch that focus solely on collecting more data, Empirical Sleep is dedicated to helping you actually achieve better sleep and get more rest.

On the checkup screen within the app, you can easily compare your health stats against other users of Empirical Sleep as well as medical norms. This allows you to understand how your sleep measures up and identify areas where you may be above or below average.

In addition to tracking your sleep quality and providing actionable advice, Empirical Sleep also offers a feature to monitor your risk of sleep apnea. With a medically-validated questionnaire included in the checkup screen, you can assess your risk level. If your risk is determined to be medium or high, you have the option to directly chat with a real medical doctor to discuss next steps (available in select US states).

To make accessing your sleep data more convenient, Empirical Sleep offers a native Apple Watch app. From your watch, you can view your sleep duration, onset, quality, and stages (REM/deep/core/awake) without needing to open the app on your phone.

Furthermore, with the introduction of iOS 16 and watchOS 9, Empirical Sleep provides watch face and iPhone lock screen widgets. With these widgets, you can display your sleep stages, sleep duration, onset, and quality right on your Apple Watch face or iPhone lock screen.

In terms of compatibility and integration, Empirical Sleep is designed to work with Apple Watch Series 3 and above. It seamlessly integrates with the Health app to automatically track your sleep segments, heart rate, HRV, blood oxygen levels (SpO2), steps, sleep stages, and activity data.

The best part? Empirical Sleep is available as a free app to download with an optional paid subscription. This allows you to access the essential features without any cost while providing the opportunity to unlock additional benefits with a subscription.
