Too long trip ,

Decent, not great

If nothing else, very simple to reset error codes vs paying for a tool to reset. Bought. A $20 Bought the pro version and it gathers a huge amount of on board data. No way to export the data. And the app is laid out pretty poorly. Worth the $4, but I see better apps out there.

LennyPal ,


Am delighted to find an app that works the first time although it may be user error for the first few apps I've tried. But one thing that this app does that none of the others offer is the ability to clear codes without having to pay. Seems most others are just offering the app for free to install but requires the paid version to do anything. I wish those people would clearly state that so I don't have to keep trying apps. Skeptical at first that this will be another disappointment but so far it is working and doing what I need it to do.

Non-refundable App Scammers with fake OBD II product

This app is a piece of garbage like many others but what can you do once paid for the app that you will never use again, right??

I’m surprised that Apple is enabling these fake app scammers loot on honest downloaders with a hope. Once downloaded app developers loot our money even if we don’t use them at all., never. This malpractice needs to stop and should allow users for refunds if we don’t like or don’t use them at all! Please stop this malpractice effective immediately and allow refunds!!
