Thief?
App loads but does not appear to do anything other than to connect to meter using Bluetooth. If you check Bluetooth connection the link to meter shows up but don’t not update the display in the app or the meter. The app has also not been updated in two years. Thus I don’t know if this is just an abandoned application for a meter that is no longer supported even though it’s still being sold or if it was sold as a Bluetooth enabled meter but never worked. Either way I feel like I was stolen from by a thief. I will change this review if I find a solution. Also the support site for the app is listed in Chinese only so I have no idea how to contact support with learning another language.
