Awesome App!!!!

Maybe you could add a Skins option for all the most famous and rare handheld calcs starting with the one I started with, which happened to be the very first pocket calc to hit the market (Hewlett Packard HP-35) which by the way for all haters of RPN, it was what the HP35 used, so it was indeed first in 1972.

Great Calculator!

Recently downloaded, I find better than the ios calculator. As a matter of fact, I prefer to use it over the scientific calculator I have purchased. I plan to buy the "for purchase" calculator later.


Downloaded this app a day ago and I already love it. It is a great resource for almost any form of calculation. I plan to buy it soon. It far much superior to other calculators.
