**PLEASE NOTE!** Any reports of hanging or freezing after quitting the app is due to a bug in the HTC Evo 4G and Galaxy Tab, this can be triggered by using the Pandora/Vlingo/Aldiko bluetooth enabled apps. Disabling Pandoras new bluetooth settings fixes the problem, but HTC/Samsung need to release a fix. Please contact their support and encourage them to fix, Thanks!
The pro version supports USB ELM adapters which are use 'Prolific' or 'FTDI' chips
* Update: A freeze/hang workaround has been found after a great amount of effort and is available in the full version in the General Preferences settings!
