It uses advanced motion sensors and heart rate technology

Unlike most fitness trackers, Fort uses advanced motion sensors and heart rate technology to measure bar speed, muscle effort, and even how close you are to muscle failure, rep by rep.
Its magnetic charging case doubles as an extra sensor for leg press and cable moves, making it especially handy for serious lifters.

Fort also keeps tabs on your sleep stages, HRV, VO2 max, and stress levels.
Weighing under 30gm with a week-long battery life, it is built to be an all-in-one health tracker you can actually wear every day.
