RE: Help me w/freedback on RPN Calc? (Free) new iOS App
Hello Mike,

great effort of yours and thank you for giving it to us for free. I played a litte with it just now on my iPhone (8) and have already come to like your flick&pick interface.

My initial observations are the following ones:

Bug (just one :-) ):
- Factorial of x>20 returns 0

Matters of taste:
- I belong to the fraction who prefers the arithemtic keys on the left side of the number keys. But I guess it would be too much of an effort to make that a user preference (swap the columns of keys between left and right).
- A backstep (or undo) function would be nice.
- A kind of "peek" function for the memory contents to see what's there without copying it to the stack. As it is now, tapping on the memory buttons always copies the contents to the stack.
- The keycklick, even at the low setting, is too loud. It would be even nicer if the tactile feedback ("haptic feedback" Apple calls it) option of iOs could be used instead of the keyclick.
- And then, again a very personal taste, I prefer colour over shades of grey. A colour scheme like on a classic HP calculator would make that calculator more appealing to me.
- And another very personal thing is that I find the "blackboard"like background quite distracting. Especially those Xs and Ys in the the X and Y registers of the stack get in the way of the values. I would very much prefer a black or dark grey background.

Keep on the good work!
