Waste

I have used this app for quite a while now and recent updates means I have to pay now just to use basic functions so I will not be using again

Won’t connect after update

Worked fine until the recent update. All lights working on WiFi dongle no issues with the dongle. I did email PNN the log and description no response.

Get rid of it

This OBD 2 scanner use to be good for years it was free and easy to use. But greedy industry you are better off buying a OBD2 scanner that doesn’t have ads or buy a subscription in order to use this device. I deeply regret buying this garbage.

Stop pushing your adapter

This is a pretty good app, but you can’t connect without the app shoving a new adapter in your face. I HAVE AN ADAPTER. Sure, offer your option once but never again.

Scam

Used to be a great app, then my phone offloaded it and I have to pay$35 to buy it again. No way to restore previous purchase. Never happened before, even though the app offloaded previously. Avoid this, use a different OBD software.

Response from developer

All App Store licenses are attached to the account you pay from. Using the same account and re-installing inCarDoc should automatically upgrade the app to Pro. You might also force an upgrade with Settings - Buy Pro (scroll to the bottom of the Settings page) - Restore purchase More details about the app at https://inCarDoc.com
