Ratings and reviews

Could not figure out how to shift or access other functions on the keys. I really liked that there were no ads. The developer responded very quickly to my comments and politely said the function was in the users guide. Please note the response did not provide an actual solution (i.e. what to press). I was looking at the app's key pad and could not see how out to 'shift' a key to gain access to another function on top of it.

I had the Radio Shack version of this calculator, the EC 4016, when I was in the seventh grade. I absolutely loved it. It was super thin with template keys. This app is exactly like using that calculator. The look and feel are so true to the 1986 original, even though I believe it only supported 6 nested parentheses.

It's wonderful. Why has no one done a true Casio emulation before. There is NO learning curve as it's a perfect emulation of a Casio calculator that those of my generation were brought up on. Other calculator apps annoy me as they think they can improve on the basic layout of the 4 function keys + - x / and = Even the Mode key works as expected in that unique Casio way. Wow also a FULL user manual. Now all I need is to find a version for my iPhone as well as my kindle fire tablet.
