I do not agree with the preceding negative comments. As someone that has used the physical 12C for years, this app is true to the original. Using this on the iPad2, I find the graphic quality is stellar. Since using RPN (reverse Polish notation) the first time, I found it logical and straightforward. If you're thinking of buying this app and you haven't used RPN before, you owe it to yourself to spend 5 minutes training yourself, you'll love it.Yes, there other free apps that purport to emulate the beloved operation of the HP 12C...and I've tried pretty much all of them, but this is the one to get. The other "free" apps are all lacking. Today I found this app on sale for $4.99 as a special for the upcoming school year (september) and grabbed it having watched the pricing for 6 months waiting for a price drop.Kudos to the designers in keeping this app true to the original, 5 stars for sure, 10 if I could!!
Keystroke rate too slow in new version
JR.JRGROUP
Excellent App, BUT keystroke rate in new version is too slow. I have to slow down entry or it misses numbers.
Developer Response
Sorry for the trouble with the previous version. Yesterday, we released version 3.1.1, which addresses the key responsiveness and few other improvements. Could you please install it and let us know if everything is working correctly now?

Terrible

How can I revert to the previous version? Don’t like the layout. The keyboard is very slow. VERY Difficult to enter decimal points. THE OLD VERSION PLEASE.
