OBD II scan tool for iPad etc?

[DRJDVM's '69]

I've seen quite a few at SEMA etc, but was wondering if any of you guys had experience using any of them....

For years I've had a program on an old laptop that worked for trouble codes and reading real time data. But now the laptop is pretty ancient and so is the program....its not working very well, crashes, doesn't seem to work with my newer cars etc

When I get a Check Engine Light, I'm trying to check the codes to see if its something I can fix ant home or need to take it in..

So its time to upgrade...looking for a home hobby type deal...not some expensive professional set up...
