One of the nice things about a real calculator is it is easy to enter numbers and do basic operations on them without looking. That's usually quite a bit harder on an emulated calculator on a touch-screen device due to the lack of tactile feedback.
I wonder if one could make some sort of overlay that you can put on top of the touchscreen when used an emulated calculator to help with that?
One approach could simply have a cover over the virtual keyboard area, with holes in the cover over the virtual keys. This would give you some tactile feedback when moving between keys.
Fancier would be a cover with actual push buttons that when pushed touch the screen with something that will register on touchscreens.
To make it really fancy, also have an "On" button that rather than touching the screen uses Bluetooth LE to communicate with something on the phone that launches or switches to the calculator that matches the keyboard overlay.
