The app has been updated finally. The connection issue between the app and KettlebellConnect was quite improved. You can transfer your workout data over Bluetooth quickly. Now, it’s worth trying Jaxjox products. Ideally, they start to sell other Jaxjox products in Japan, for instance DumbbellConnect and KettleBellConnect “2.0”. I believe they would be popular even in Japan. At least, absolutely I’ll be in!
