To track movement and activity, the revamped Fitbit app uses Apple's "M7" motion coprocessor. First introduced with the iPhone 5s, the M7 chip accompanies Apple's standard A7 processor and captures motion data from the phone's compass, accelerometer, and gyroscope, facilitating the continued capture of movement without significant battery drain.
With MobileTrack, the Fitbit app is able to track steps, distance traveled, and calories burned. Fitbit's physical offerings, including its newest Fitbit Force band, track those standard metrics along with active minutes, sleep, and stairs climbed.
Along with MobileTrack, the newly updated Fitbit app also includes redesigned alarm settings, custom water goals, and several other design enhancements.
- The Fitbit app now features MobileTrack which offers basic Fitbit activity tracking directly using your iPhone 5s.Earlier this year, Fitbit competitor Nike introduced a similar app, called Nike+ Move, which is also designed to track physical activity. Several other apps have also been engineered to use the M7 coprocessor for measuring movement.
