Close but no cigar

As people have said, this basically has to be your only Bluetooth connection. However I’ve had no issues with the diagnostic scans, clearing codes or any of the features. The UI of the app isn’t great. Wish I could change the color scheme to something other than orange and it would be nice to be able to customize the picture of the car to match my actual car. Good app but needs more customization

Don’t buy this

It just doesn’t work, bought it for home depot used it once that it. Just doesn’t work again. The app just says connecting to device. I have a Subaru forester. You have been warned don’t waste your money like I did unfortunately.

Garbage

It worked for about a month. Now I can’t login or create a new account. I am getting the “timed out” message of death. It would be nice if the company did something about the negative trends with their product but they’re making a killing off selling the readers at Home Depot.

Disappointed

Disappointed on the fact that you can’t see anything or be in the app without being connected to the bluetooth scanner. Pretty much useless, unless you have the scanner connected. Would be nice to have a review of codes/information of your car without having to turn on your car and wait to be connected.
