This is a terrible app. I wish I could rate it a zero. First, it is in Chinese. Is there an English version available? The App also does not recognize my Fastwheel Eva Pro. This is so frustrating. I have had my Fastwheel now for 3 weeks and I have been looking on the web for any way to make the App recognize my Fastwheel. No luck whatsoever. Now my Fastwheel seems to go slower (on a full charge) and I would like to be able to somehow control the speed settings. No luck there because the App will not even recognize my Fastwheel. Add to that the App is only in Chinese. Anybody out there have any idea to fix these 2 problems?
