It's Exactly the Same (except much faster). I am a financial advisor with ver 30 years of experience in the field. During that entire time the HP 12c has been the staple calculator of the industry. This calculator is absolutely identical to the one I carried around with me for many years. When I set my original pocket version 12c next to this smartphone version, they are the exact same size and they function in the exact same way. (I own a Samsung Galaxy Note 4 phone). The only difference is that this smartphone version is much, much faster.
Great app work a bug or two Just concerned about the access required to media as well as control storage
It loads very slowly. It may be my hardware; however, some other competitors' products load twice as fast.
Computation slightly off at 8 decimal places.
It worth every penny! Best calculator app. Better than the real one
HP 12C business calculator Elvis Pfutzenreuter has done a great job.. I have used HP12C for more than 20 years now, and this app for Android is very useful. Can Elvis improve a bit? For instance, when the unit is on a flat surface, no option for a landscape mode of calculator. This will be great. July 17th: After the recent update, there is a small irritation in that the APP does not start at first. It needs two or more attempts of touching before it actually "wakes up"!!
Engine updated, fixed CLEAR PREFIX bug that hung the calculator for certain exact powers of 10.
HP 12c Calculator app is now available for business professionals and students.
