Works but

Claims to measure horsepower and torque, but I've never been able to find it. Emailed developer several times and have yet to receive a response.

Still works with iOS 14.6! … hasn’t been updated in 5 years though …

Surprisingly still working with iOS 14.6!, (2021), even though the app hasn’t been updated in 5 years :(

Was recently getting frequent “Connection Failure” type messages, but discovered that turning OFF Bluetooth, even though I only use WiFi connection to my inexpensive generic ELM327 OBD2 WiFi only device… It Still WORKS! : but for some reason iOS only supports WiFi connectivity on genert ELM327 OBD2 readers.

This free app version does ~90% of what other paid version apps do: though mostly I just need it to pull/wipe Codes, monitor Idle RPMs, test readiness diagnostics, and air/water temps.

Of course using the ‘Dashboard’ on test drives, the Diagnostics and Performance screens, and perusing my custom dashboards also, gives me all the basics (and more) to troubleshoot problems, and monitor the success of my repairs etc.

Thank you to the developer for having made such a nice little free tool that still works correctly with my generic ELM327, even though my late 90’s project cars are technically too old to be on the modern supported databases of most newer paid reader apps!

Works great!! Make sure to select your tool.

I really like this obd2 tool. I use it with the Elm327 and it does a lot more than I really ever need even. I even tried one of the paid OBD2 apps and still I think this one is better! Make sure you select the OBD2 tool you are using and select wifi or Bluetooth. Great app guys as far as I am concerned and I have used it around a year. Thanks!
