Ratings and Reviews
It works most of the time.
I’ve been using this app for about 3 weeks now and have had to delete it and download it again twice because the text on the goes inverse for no reason and won’t switch back. Other than that it does what it’s suppose to do.
Update back to 5 stars.
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.
