Fitbit estimates sleep stages using a combination of movement and heart-rate patterns. While you’re sleeping, your device tracks the beat-to-beat changes in your heart rate, known as heart rate variability , which fluctuate as you transition between light sleep, deep sleep, and REM sleep stages. Sleep stages are traditionally measured in a lab using an electroencephalogram to detect brain activity along with other systems to monitor eye and muscle activity. Fitbit’s trackers can’t match this level of medical accuracy but can estimate your sleep stages every night. Apple Sleep uses motion sensors, heartbeat sensors, and microphones to detect micro-movements to track of how deeply users are sleeping.
In addition, the Inspire 2, Charge 4, Versa 3 and Sense all feature Caller ID and Text notifications, buzz and show on screen who’s calling when your phone rings.

But that is not as impressive as Fitbit battery life that can last a week or more between charges.
