An Oscilloscope on an iPad. Wow

This may sound funny but I bought this on a whim.
I was an engineering technician back in the late 80s and remember the old Tektronix oscilloscopes.

Imagine being able to simplify all those knobs , switches buttons into a simplified touch interface. Oscilloscope shows just how that can be done.
Simple to use UI, great graphics.
