Customer Reviews

Incredible Support

First of all, having Bluetooth connectivity for the JB4 has been a valuable enhancement. When I had a problem with the BT hardware, I sent the unit to Donnie and after a few email exchanges, he fixed the problem and sent me a replacement unit. The app quality is outstanding and support all the more so. It is amazing that there is such an outstanding product for a niche application. Just get it! If you already made the plunge to get a JB4, the Bluetooth interface will greatly enhance your investment.

Username/password server fails

The app was GREAT until the username/password was implemented. Now I can't use my iPhone turned iPod for sole purpose of using it to connect to JB4 unit. Remove the username/password and this app will gain back its 5 star rating.

Not working properly screen upside down and backwards can't read anything

I just bought this app I can't read anything it's all backwards upside down can I get some help please?
