Does the basics better than competitors. Today my van lost the torque and eventually, the check engine light came on. Some apps require money for a single faults reset, others require a full version of the app and they still wouldn't do what you'd like. This app showed me the errors, let me reset them and eventually I could make a workaround the fault and keep driving home. Thank you so much!

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)

It connects easily and it gives u many parameters to look at. But you need a PhD in engineering to understand it most of it. Simple ones are fine but if each included a simple explanation it will make this app the best in the market; Also another thing is that I can't email the log files or download them in txt or notepad++ files so we can easily read them.
