Overall it's in good app there's a few bugs that are annoying and a few other things but all in all I'm glad to pay for it I just wish that these bugs would get fixed like I can't put in what size engine I have which makes a big difference even though it reads it overall though it's the one I use so that tells you I like it

pretty good Right off the bat, if it imported the car info from the free version, that would be great. It would also be nice if the widgets you can see more than one at a time. l like the lig that i can place maintenance info right here. Most these apps don't do that. For an app that gives basic info, its not bad. Pretty good.
