Anonymous6 years ago000can this belt perform the fitness test (to determine VO2max) without the assistance of a sports watch (only with mobile phone)?Show in original language (German)Anonymous6 years ago • purchased this product011purchased this product Helpful answerFor me, the band is connected directly to the iPhone.
