Mechanical apps for a machinist?

[Doug103]

Maybe you can help me out. I'm looking for a couple of apps that I have on my Ipod touch that I use for work a lot. 1 is called "Screw Info" dedicated to thread spec and torque specs with a lot of other great info.
The other app is called "Journeyman". Its all about machining.
Gets old carrying around my DX, ipod and the company BB.

Thanks for any help!
