Connectivity issues
Constant connectivity issues, and they clearly never update and debug.
Don’t work new version
All new version don’t connect with old version jb4 kit . What can I do ?
Wrong app for new bt adaptor
Wrong app get jb4 pro!
Did not work
I couldn’t get it to connect. I cannot find any way to contact Support. The regular JB4 PRO app works fine wirelessly.
Gauges freezing
I actually love the app and the capabilities are nice. You can do a lot. My problem is the app keeps freezing when u have the gauges open after doing a pull. I have to toggle to the maps menus and than back to gauges for them to show live feedback again. Maybe this is something I can change in settings??? If so would change to 4 star review

Yes
App going to sleep fixed in the last update
Screen turns off
Screen turns off since ios26.. still waiting for a fix..
screen turns off
ever since updating recently, app auto locks and makes monitoring gauges nearly impossible
iOS 26 update won’t allow app to stay on screen?
App works as expected, but since iOS 26- app no longer remains logging or showing data past lock screen timer? Please update to allow use during driving! Thanks
Screen turns off on iOS26
Couldn't find another way to reach out to the developer.
The app works fine, however since updating to iOS 26, it no longer keeps the screen on when you're using the gauges, which defeats the purpose of gauges.
On previous iOS versions, the app would keep the screen on and the phone unlocked while using it so you could view the gauges and record logs.
Please get this fixed or add a setting to force the screen to stay on!

Competent Turbo Controller
Please automate the third gear logging.
Ok
Worked great until I installed iOS 26… now the screen turns off / goes to sleep with the jb4 gauges displayed - unlike before
Screen not running
Screen does not stay on when driving around have to keep touching screen or re opening screen
Car Play Support
Please develop car play support so we can monitor gauges on our car screens!
What a pathetic trap!
I would have happily purchased the “fancy updated version” of the app when I was comparing this one vs the pro version, but as soon as I realized that the $700 I paid for the JB4 module and Bluetooth adapter for my 2024 Raptor was incomparable with their “free app” - I’m furious. I have no option to change tunes without it, which is quite the effective pay wall. I’m going to actually submit a case with my states AG for an illegal practice called tying, which is where this company has bundled a unwanted product (their app) to the sale of a desired product (the hardware), which is by definition an unfair trade practice and engagement in tying under Maine consumer protection laws. Search your state laws and send that email, this is not ok - especially where this isn’t disclosed up front.

Works…but
So the device and the app work pretty well. I have the device for a 2022 ford edge 4cyl. Definitely has a much smoother drive with it on, mileage is better. Easy to install and app is simple to use as well. My issues are that I’ve had to purchase the app three times now, because I go through phones like crazy, and apple doesn’t seem to want to save information very well. There is sometimes where I feel like I have to hit the quick mode I want after the initial start up, because it doesn’t feel like it’s giving me the smooth power, but when I hit number 3 and it loads then it’s good. But I think sometimes during the initial start up there is some connectivity issues. Might just be the phone, since they are just monitoring devices for the government.

Just downloaded and not happy
Purchased the app a few years back when I worked for a BMW performance shop and hadn’t used it in quite some time. Downloaded today so I could interface with my wife’s car and I have to pay for an app I’ve already purchased once?! The whole reason I paid for it the first time was so I could use it when I wanted. Honestly you’d think if you bought a $500+ programmer and paid the extra for Bluetooth connectivity bringing the total over $700 the app would come with it.

Only one thing left to improve!
Great app for a great product but it really needs to be integrated with Apple Carplay. I’m hoping for the upgrade soon. Then I will switch my rating to 5 stars.
Apple car play needed
As stated in title, we need this app on you infotainment
New Gauges
It’s needed the app for my tuner. For the most part it’s great on the fly. I’m able to check my logs, switch my map, change my tune. Love it. Unfortunately I’m missing some parts of monitoring. I’m sure it’s due to availability and car. But I’m unable to get my Trans temp, oil temp, and some other. I also do wish there are more different styling gauges. 5.26.25 - So the update on the app is nice. FYI…the graphs and such can be found in the files folder if you have an iPhone.
