Sensitive and normal are the two settings available on the Fitbit tracker. The sensitive setting should be used for very detailed sleep reporting as it causes the tracker to record nearly every movement as time spent awake. Users with sleep disorders or who wear the tracker somewhere other than on their wrist would find this setting useful. The normal setting offers a basic idea of sleep patterns and only counts significant movements as being awake.

Sleep mode, restless state of sleep and awake are the three states that the Fitbit tracker logs. Sleep mode is recorded when the body is completely unmoving. Rolling over and other small body transitions are logged as restless sleep. Movements so large or frequent that restful sleep is impossible are logged as awake. Because the Fitbit tracker uses autodetection based on movement, sleep could be logged when a person is awake but not moving.

Greater accuracy is achieved when the Fitbit tracker is worn on the wrist of the non-dominant hand. This allows the tracker to capture the fullest range of motion.
