I tried a few other highly rated rep counter apps and jump rope apps and they were extremely inaccurate, or just didn’t provide much of the information I wanted. I held back initially on getting this YaoYao app simply because it wasn’t free, but finally took a risk and got it. Immediately I noticed when I started my jump rope workout that the counts were very close to the actual jumps, and I LOVED how I could get loud verbal announcements for every 50 jumps or heart rate - with many options I could set. Finally, I could jump without thinking about counting, or using some method of keeping track physically. Then I was thrilled after a few more jumprope workouts to discover so many other useful, thoughtful and professional features, this is on the level of the type of features the Apple Activity App in quality and range of measured, counted and integrated metrics. The graphs and the badges you can earn, it all adds so much more to the jump rope workout, I love it!!
