The Gymwatch armband is a gym-tracking device that, instead of measuring cardio-focused parameters (like most gym trackers), measures strength and motion. This means it is targeted towards gym-goers looking to gain weight and build muscle, who are often overlooked due to the assumption that everyone goes to the gym to get slim.

Gymwatch has a built-in accelerometer, gyroscope and magnetometer, which work to record movement and strength. The system tracks strength across different types of lifting exercises, whether they involve lifting free weights, using a pulley system (like a row machine) or lifting your own body.

The Gymwatch system uses various formulas to determine different aspects of the user's strength. It can even provide live feedback on posture and technique.
