JB4 Mobile

Edited. Back to 5 stars. Donnie fixed the graphing issues and is back to normal. Anyone that does not like the latest update. Try the revised one on the TestFlight app. You may have to ask for a TestFlight invite. Please revert back to the old version. The update is terrible. Graph graduations are better at 5, graph buttons overlay on phone icons take multiple presses to close graph? Let us scroll to the end of the graphed log, pop up for detailed graph info back to normal as well. All around update makes this app worse. I’d give it 5 stars the way it used to be. Icon legend is harder to read. I’ve emailed you during the test flight version that it was bad.

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.

Love the real time data logging through your phone via Bluetooth. Makes things a lot easier to monitor. I always have it on whether I’m driving to work, going to the gym, test driving the car etc. Much more convenient than a laptop!

It’s an amazing app! A must have for Jb4 owners. You can change maps on the fly via Bluetooth, in case you can’t find e85 and have to run on 93 only, it’s a cinch to lower boost a bit so you don’t damage your engine! All the different read outs are very accurate as well!

App is freakn awesome! So much easier to work with a phone than a laptop. Please change the background color as it’s too dark to read and if gauge selections can be adjustable from 1 to 6 gauges this would make it even friendlier to use.
