Apps for vehicle inspection

Has anyone tried this app?

It can be very useful when it comes to buying used vehicles. However, I ask about it every dealership I go to, but unfortunately nobody wants to disclose all hidden issues of their vehicles.

here is the link to Google Play

Have anyone seen the actual reports based on this app or similar to this one?

Here is how this vir looks like

I wish it was mandatory for every dealership to use such an app

Any thoughts?
