GoPoint GL1 auto diagnostics
"Check engine? Check it for what, exactly, dashboard light? Give me more information!" This app for your iPhone, iPad, or iPod Touch will give you all the info that stubborn Check Engine light refuses to relay, so you can know exactly what's going on with your car and how urgently it needs to be repaired. Sure beats going all the way to your auto shop when all you needed was a new air filter, doesn't it?
