gaborsajo ,

Works great.

Have a small suggestion.
I noticed a while ago on the iOS app is that the top of the screen and menu button are cut off on phones
With the notch and rounded corners.
Makes it inconvenient and not polished looking.

The developers need to account for the safe area layout guides

Developer Response ,

Hi gaborsajo, thank you for reporting this. Our updated app will address this issue and bring about many new features very soon. Thank you for such a great review, all the best!


Rip off

Wasted so much money on the license, on adapter cables and can’t get ANY support from anyone, the developer OR the shop that sold me the adapters. There’s so many undelivered promises. F this app.

akgambino ,

Awesome app, better customer support!

Can’t say enough about the guys at PTF and the Bootmod3 platform! Hands down the best tuning platform available for BMW, keep up the good work guys!
