Bluetooth Only. OBD Boy is one more OBD2 ELM327 application for Google Play. It's a work in progress application but it can't mess up your car since ELM327 can't write anything to your cars communication networks. This application is a one man project and most interesting one to me. Support app development by sending feature requests, by sending PIDs and math formulas and especially by rating the app. I started making this due my own car has a weird problem. Unfortunately I realized that this car needs way different electronics and software to read data out than what I can do with ELM327. Maybe it can do more. Future development will reveal that.
