User reviews

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.

doesn't work

I stopped connecting to Elm via WiFi after the latest update.

Ok

Works fine when it connects but it has trouble doing so

Is anyone maintaining this app?

Well, I can’t give it one star because it has got me through several issues. I just get really frustrated when I’m unable to connect to my OBDII reader. I can connect to the OBDII reader’s Wi-Fi through my phone settings just fine, but when I open the app, it’s very difficult to establish a connection.

Much improved and good enough for me

Tried using this 5 years ago in iOS but it wasn't compatible with my cheap obdii dongle. Now it seems to work great and I may not need to go back to using an Android device to work with said dongle

The free version is adequate for reading and clearing standard odbii codes and basic ecu engine statistics, etc.
