The Future of Instrumentation is Here

This is incredible. To think that with a device the size of my hand, I can acquire and send information about my complex industrial system running on my 9191, humbles me. A long time ago, we discovered fire, and it forever changed the human race. Well, Prometheus seems to still be watching over us, and today, thanks to this app, our race is again forever changed. Thank you, National Instruments.

Wow almost 3 years later and still...Only supports 1 module?!?!

Typical NI to release some half baked software. I'm surprised there isn't something else I need to buy just to get the 1 module to work.

Incredible App!

I have been waiting for something like this! Wireless Data Acquisition straight to my iPad!
