Doesn’t work
I used the PRO version on a Apple Watch but it didn’t work very well. As soon as i removed my hand from the bar, the sensor seemed to be irritated… if i think about how the sensor might work, it’s kind of clear that it will be problem if you move it while you gaining hight… but honestly if i can’t remove my hand for a grap or a boardoff it just doesn’t make sense… i prefer the WOO…
