Missing reverse side

Missing the reverse side of the 15C, which contains some very important programming information. How about making it a part of this app that can be easily referenced from the drop menu. Otherwise, I'll hav.e to copy it to my desktop as a jpg.

I think it's great

Having owned many HP calculators, I think they've done a great job with this one, and it's nice to be able to use it with the regular Mac keyboard.

I wish they would do an HP-16

Rough around the edges on modern Mac

I love the old 15c, and though this version is very inexpensive and generally functional, it is a bit rough around the edges. The graphics definitely need to be upgraded for the retina display - I find this is quite “blocky” from displays to key graphics. The other surprising thing is that it is noticably slow. I’m not sure if this is due to running on Yosemite, or if it is not sufficiently optimized, but operations that I can run on the Apple calculator and then compare to this version of the 15c (like raising a number to a double digit power) take noticably longer here. Doesn’t keep me from using it, but definitely something to be improved upon.
