Greatest scientific pocket calculator in 1975?

Small suggestion? The icon for the 34E emulator may have a bit too much color enhancement going on. The RCL button sure looks more greenish than gray at least to me.

Just a thought.

I find myself using the RPN-70 SD as my do to basic math calculator, FWIW.

I never held a real HP-34 in my hands, so I had to rely, colorwise, on the friendly user who suggested RPN-34 and photographed his own calculator on the kitchen table... I agree that the keys on the app itself look less greenish. I've made a note to change the icon a bit in an update.

My everyday calculator is the RPN-45. I use the day-of-the-week function surprisingly often.
