Either way the app takes the data from the dongle and shows it to you on screen. MPG, Tach, G-forces, boost, error codes etc... I'm gonna get one it will take like 2 weeks to arrive but, I'll let everyone know how it goes! The Dongles come with software for PCs but I doubt you'd want a computer in the car with you. A phone sounds more reasonable. As for iPhone users, Android is better but, I'm sure there is an app similar to Torque on the appstore which can do the same. WinMo phones the same all others, SOL. Enjoy!

Android software developer's website (Torque)

There is one for the iPhone in fact, it's called Rev by DevToaster. However I believe those BT wireless device aren't yet supported by the iPhone except for the Kiwi WiFi wireless OBDII's which are the ones in the $150+ range

I do have a Magellan cradle where I dock my iPhone when I drive.



Getting one of these wireless (wifi)/BT dongles might be a good alternative to the Scangauge as they seem to have more to offer in terms of features -- please do keep us posted!
