Just Like The Original
This is a terrific emulation of the venerable HP-15C calculator -- the best one Ive found in the App Store (and believe me, Ive tried the others). Works just like the original, and it comes with a wealth of help functions -- pressing the Help button reveals the original User Manual and Advanced Functions Handbook in PDF format, as well as manuals for a number of other HP calculators. And its always as close as your phone.
I gladly give this app 5 stars!
