Best and only app for you R53

The dev is very responsive to feedback and continues to add features and updates. Easy to navigate, easy to read and give excellent data. Plus you can code some features on and off. If you have an R53, you should have this app.

Hands down, the best OBD app for older Minis

I don’t EVER write reviews, but this application, its usefulness, its design, its reliability, … It is rare to come across anything on the App Store that delivers on every aspect. Phenomenal.

Just what I needed

Great app for logging data on my R52 MINI. Worked well on my iPad and was way more convenient than having to haul my PC along for the same job. Highly recommend if you want a portable way to check codes and log data.
