Ratings and reviews

Edit- When the app doesn't "time out due to endless loading" or refuse to show every make/model, it is good. Not a bad app or device. It won't auto read any vin I have tried it on, but this device smokes any basic elm 327 device. Definitely worth the cost. I wish I had known it had a companion pro version for $50 more before buying this one, but I don't regret my purchase. Decent bidirectional controls.

Love so far. Been using for almost a year with our topscan Bluetooth dongle an the only complaint i have is saving the report. I cant find where its saving it to so i can pull it back up. I e been emailing an texting it to myself so i can keep them available. Also wish it could do like a dash board mode. So i can use it as a gauge cluster.

It used to work great and was extremely useful for use on my car. I hadn't used for a while and needed to use it today. Spent a bunch of time updating and then scanning over and over again. The app would either force close or it would lose connection to the device and not give me a report.
