Japanese writing? Yeah I know English isn't the international language. Also it doesn't count accurately. It missed many of my jumps so it's worthless. However it is nice that the watch can be used as a stand alone device. That is the phone doesn't have to be in your pocket. Just need to fix the jump counter. Maybe it's not sensitive enough?

Update Aug 2017. Doesn't work very good at all. Just did a practice jump and it only counted 1 jump out of over 100. Nice try.

Update 2019 with iWatch5. Still not very good. Hardly records any jumps. It might get about 5-10% of my jumps unless I really over exaggerate my wrist motion which is not natural, and then it’s still not very accurate. Still not impressed. I even set the sensitivity to max. Made no difference.

No clue what most of these other reviews are seeing. Unless you are doing one jump per second, which is incredibly slow, the counter is wildly inaccurate. I held off my frustrated review on day one and decided to give it a chance. I’ve used this just about every day for the first week and the problem is the same. For every 30 seconds of jumping, I counted ~60-80 jumps. The app says only 30-40...EVERY TIME. Consistent, but useless and not worth it, even if it was free. $3 for this is absolutely ridiculous. How do I get refunded for this trash? I expect that the answer will be that I can’t.

I wanted to see if the counter worked. It doesn’t. I like to speed jump, and when I get 4 rotations in a second which isnt even the fastest it only counts 1. Maybe if you’re jumping slow enough it will be good. I can see it being good for just a nice slow jump or possibly a workout but don’t count on it counting properly.

On the other side I do like that it has the HIIT timer on it now, but that is honestly the only good thing about the app for me. This is not saying it works for other people. Just does not work for me. I record to check for form and to count, and like I said it isn’t even close. Also like I said completely different type of jumping probably than what it’s meant for.
