Used the free version for years, as it have me just what I needed for basic info and check engine diagnosis. With a recent update, much more of the app is 'Pro version only', which is the developers right but makes the app far less useful unless you choose to pay. Time to find another app. As a bonus, I'll end up with a little better user experience (better ordering of monitored items, for example, making it easier to find the O2 sensor in a list of options)

Das ist hier die Android Version und der Kauf erfolgt direkt in der App. Das was Sie in dem Shop gekauft haben, ist die Software für Windows und hat mit der App nicht zu tun. Das sind separate Produkte. Wenn Sie unsicher sind, dann wäre es sehr ratsam vor dem Kauf den Verkäufer zu kontaktieren und alles zu klären.

I bought the Pro version, and it's worth the price. I'm a Smog Tech and when I need to show a customer the state of their vehicle this app displays the codes and monitors with a lot of clarity. I don't like that all the of the Freeze Frame data such as Fuel Trim information is not displayed. There had been times when Permanent Codes were not displayed. Since the last update, you need to use the Dark Theme to view the control buttons, such as the ones used to select data pids.
