I'm a Single lady and independent person, but not very car savvy. I can do minor stuff, but I leave the big stuff to the professionals. this app is AMAZING! I have diagnosed a few things and told my mechanic exactly what was wrong. it was correct. This app is so easy to use! And free! I was intimidated at first, being almost completely clueless, but directions were clear and I get all the info I need. my fav part is where it links you to articles and videos relating to the repairs needed!

It's disappointing that it seems like it's going to give you all the information you need until you plug it in for the first time and click scan and then it forces you to upgrade to the pro pro version. it's only 5.50 lifetime it says but it's still a pain when I was in an area without any signal and I wasn't expecting to have to upgrade.

WAY BETTER than any other BT OBD2 scanner I've bought in the past! Easier interface, faster real time data, it makes my "casual driveway mechanic" on my own vehicle feel like I can make an informed decision. (and YES, it convinced me to take it to a knowledgeable/certified shop since the data collected showed it was beyond a simple fix👍🏻) I would recommend this App and the scanner to every friend and family !!

Great software. I found another use for it, other than diagnostics. I recycled an older cell phone and loaded Car Scanner on it. I set up a dashboard with different engine checks and used it to have real time feedback from the OBD. If you like monitoring the exact temperature of your coolant, for instance, you can create a dashboard and add coolant temperature to it, as well as oil temp, or anything you want to monitor. You can even set up alerts so that you know right away if there is a problem

Fairly comprehensive The only thing I wish it could do is program keys and remotes, if it is there I haven't found it yet. Only used it once to realize it was good. Previously I had used another app, but had limited info. I thought my Bluetooth reader didn't read right. I was looking at another reader ($400+) but decided to look into this app first. Sooo glad I did, almost every option was suddenly there and functional.
