Updated 5-28-2025, issues appear to be resolved, the app and OBDII device are working very well now. Original Review: I got a warning this app is malware.

price is a bit much. not everything needs to be a long term subscription service for over $100. this was a great product that has been ruined by a paywall some things are kinda hidden but a couple minutes of poking around and you should find everything just fine. Tons of options. Gives you the code and what the code is then it gives you links of how to fix the problem. I'm truly impressed. *home mechanic*

Annual Subscription fee. App has the features you want but the user interface was confusing. App forced me to log out, can't save a set of favorite live data streams - have to go select from 200+ each time. In Live data stream playback you have no controls (forward, reverse, jump ahead), you must play back the entire file just to get where you want. Could not find live data monitoring function for my Toyota or Honda; maybe it was buried in the menus.

They want you to continue to pay for something over and over. They say that it's for continuously updating and R&D. My truck is not updating and improving in R&D! A free year of use and then it's subscription hell for the rest of your life. I can see them wanting you to pay for an upgrade or data packs after the 3rd car but it's current setup is a waste of money. What about a right to repair your own vehicle? This subscription is a step towards having to pay for that right.
