still reports errors with odd mileage. 102000 km or 10400 km. My car has done 42000 miles which is neither of those. INPA shows FAST with correct mileage. so clearly a bug. Carly asks to contact, which I've done plenty of times before and since. They never follow up to fix the bugs. not good company procedures.

app connects to a paid device from Carly but is basically useless without paying for a yearly subscription . subscription for their mechanic service to inform you about the error codes detected, no subscription = no codes = not even the marketed function. after contacting Carly, I was basically given the cold shoulder with the comment " should have paid more attention before making your purchase, basically. ". the app connects,reads and identifies, yes. need subscription to view results, yes.

I purchased the Full version with a lifetime license in 2023, but now, in 2026, the app only allows me to use the Lite version. Contacting support and opening a ticket did not resolve the issue. I also tried uninstalling and reinstalling the app, but the problem remains. Unfortunately, after paying for a lifetime license, losing access to the Full version is very disappointing. I would recommend avoiding this app.
