The free version allows checking how plug-ins work, how many Electronic Control Units are read with the plug-ins. If your OBD scan tool ELM327 supports your car protocol commands, all available parameters will be visible, but the values of some of them will be closed with a # symbol until the plug-in will be purchased.
The correct operation of the program is not guaranteed if you use chinese ELM327 v2.1 adapters. We recommend to use high-quality v1.5 adapters.
Recommended adapters OBDLink, Viecar, Konnwei KW903, UniCarScan (

Good app, lacks user oriented design. Seeing your response, I still strongly believe that it takes way too long and way too many button presses to get to the data I'm actually using the app for. I opened the app to check the voltage across the CU. It took 4+ button presses and 30 seconds to get that data. Using torque, it's 5 seconds and a swipe at most. I don't care to see the individual steps to connect to ECU. I just want it connected ASAP. Why do I need to click READ on the table screen?

Thank you for your feedback! 1. Automatic connection in the application is already implemented. In the "Settings" menu of the "Connection" tab, check the "Autoconnect to the ELM-adapter when you launch the App" checkbox. 2. The ability to connect to the dashboard or to the data stream when starting the application in development.

All its missing is bi-directional controls, which would be perfect plus one more star. This app gives me more module codes than my "go to" scantool. Which suprised me. Granted the graphing meter lags a very slight amount, maybe a direct connection to the DLC would resolve this, but everything else makes up for it. The only issue really with the graphing, is watching an oxygen sensor. Thats a sensor that moves fast, and a slow response could lead a technician to believing theres a sensor issue.

Thank you for your feedback! We plan to implement support for active tests in the future. If your data is slowly updating when viewing graphs, reproduce the problem and send us the logs from the application (Settings - Debug log - E-mail logs). In the letter generated by the program, describe the problem in detail. We will try to solve it.

This has the most parameters for diagnostics than any app i have tried. Its dashboard is great too. The user interface could be simpler to chose between the ecm and tcm but it will not take much getting used to. I had a major issue transferring the license it to my android car stereo because I had 2 accounts on my phone when I purchased it. It paid from one account and stored the purchase on the other. I also love the fact the developer cares because they give feedback from most reviews.
