In the activity-tracking race, Lark puts in good effort but doesn’t quite measure up to the competition.

Larklife introduces a unique and simplified app experience to the recent fitness-tracking craze, but its clunky wristband and high price hold it back. Better and less expensive gadgets abound.

This bracelet tracks your activity and sleep patterns to help you lead a healthier life, but it doesn't go far enough.

Larklife is really a combination of three different products — a daytime wristband, a nighttime wristband, and an iOS app. Together, the system tracks basic fitness statistics (calories burned, distance traveled, steps taken), food eaten, and sleep.
