It does work on devices without a menu button, took me a while to figure out but if you rotate the screen to horizontal there should be a little menu icon in the lower right hand side, at least that's how it worked on my 2012 kindle fire HD running cm10

Bought a bluetooth ELM327 from China. Connected it, car ignition on, this app 'recognized' the hardware plus the protocol and BAM! we're in business in no time. I've used it extensively with no crashes or hangups. Recommended!

I have a HTC One and you have to change in the settings what the right button does. You can make it a menu button just tapping and holding brings up all open apps. The app gives me readings for almost everything including error codes when my check engine

Has a lot of cool other gadgets but I'm a simple guy who just uses it for preventative maintenance and its helped a lot. I've had this app for maybe 3+ years and I can't complain.
