Fitbit Force General Information &
Specifications

Sensors and motors

Your Force uses a MEMS 3-axis accelerometer that measures your motion patterns to
determine your steps taken, distance traveled, calories burned, very active minutes,
and sleep quality. Its altimeter also measures floors climbed. Force also contains a
vibration motor, which allows it to vibrate when alarms go off.
