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.

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.

Easy to clear codes. Hard to do more

The app is easy and effective in identifying and clearing codes. Advanced diagnostics (with purchased advanced version) are less effective. It does not list the correct engine option for my 2006 Odyssey and gives a failed diagnostic for an O2 sensor that does not exist (Bank 3. Sensor 2), according to manufacturer specs. Two inquiries to support email with no response. Don't want to replace all sensors if only one is bad. Disappointing.

Developer Response ,

Sorry for inconveniences. We always happy to help and answer all mailed requests for support. Unfortunately we does not receive any requests from WolgeyMN and can't trace any other unanswered mails. Please note, that theme with O2 sensors naming is discussed at our forum https://incardoc.com/en-us/thread/o2-sensor-names . Sincerely yours inCarDoc Team
