A step-counter: We do not count steps because we believe they are irrelevant to your physiological performance and overall health. A GPS watch: While you can track distance within the WHOOP app, the device itself does not have a GPS monitor.

What does the WHOOP track?

WHOOP tracks more than hours—it analyzes the quality of your sleep. Every night, WHOOP calculates your sleep performance by measuring the sleep you got compared to the sleep your body needs. You'll wake up to a Sleep Score from 0 to 100% that lets you know how well you slept.

What is more accurate WHOOP or Fitbit?

Data points are taken at a rate of 100-times per second by the sensors on the Whoop 3.0 device. That's way faster than Fitbit. The results are accurate; you get both a satisfactory device and the best tracking app. In addition, the app manages your recovery data.
