Biceps Curl Counter (Camera)
Pick up your dumbbells and let the camera count your curls. It measures your elbow angle in 3D and counts a rep each time you curl all the way up and lower back to straight arms, with either arm or both together.
Half curls are not counted, and the coach tells you to curl higher. Set a goal, hear each count, and check your form score and rep speed afterwards.

Frequently asked questions
Does it count both arms?
Yes. Either arm or both. A rep needs the arm to fully straighten between curls.
Does it work from any camera angle?
Yes. Joint angles are measured in 3D, so front, side and diagonal views give the same readings. Keep the camera upright and your whole body in the picture.
