CarPlay

Please add this app to Apple CarPlay. It would be nice to use my car’s screen to see my gauges as opposed to my phone.

Oil temp font

Great app, as always, but the font size for oil temp on the bar graph is too small and does not match the other gauges. In case
this matters, car is e82 with N55 engine.

Worth the buy

You might think it’s a lot at first but when you actually use the app and see it’s capabilities it’s all worth it.

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.

No CarPlay??? Seriously?

I spend $600 on the JB4 and another $28 on this app and I have to keep my phone out to see the gauges. Insane. Despite that, app
works great. CarPlay is a no brained addition.

Water temp and oil and trans read in F only

Hi

Thanks for the update

But i notice that JB4 app version 2.5.1

Water temp and trans temp still showing in F instead of C
Even when units conversion option is selected

Only one that goes to C is the IAT

Will this be fixed soon? , please fix

Keeping the app updated

The overall experience of the app is good however I’m surprised to why the developers do not release the capability for apple
