I used this app since my 1st gen iPad. Now, several iPads later I've tried out at least a dozen others, probably a lot more than that but I keep coming back to this one. I prefer RPN and I haven't found an app better than this. The memories are visible and easy to work with. It's crisp, uncluttered and intuitive. It's easy to work with. It was well designed years ago and is still the best as far as I'm concerned.

Has the needed bells and whistles. Has a tape of prior calculations, unlike the others. What more could you ask for? Ck
