More updates would be nice, as would deeper integration to load the Navigation app once connected.

A well designed odbii app. The interface is way nicer then torque. Trouble code functionality rocks. Supports biodiesel! poor odbii hardware support..

Dev isn't updating paid app as frequently as free one! Doesn't reply to emails. :-(
I tried several other OBD apps (including the popular Torque) with my new BAFX Bluetooth adapter. All others would not connect or continuously drop connection. This is the only app that seems to have a rock solid connection. I quite like the UI and the options as well. Setup to scan DTC's before each trip. Nice work!
