12C Financial Calculator I used an HP 12C calculator from shortly after its introduction through to the 1990s when it went missing. With 'reverse polish notation' it was a lot easier to use than regular calculators. And the conversion between number bases filled a need for me at that time. So I am pleased to have a 12C back in my hands. As I don't use all the functions at this time I have held back a little in my rating.
Great program For people used to the 12C this is an awesome app. Only issue I have is it takes 3 to 4 seconds to start, so I many times hit the button again thinking it didn't register first touch to which a few numbers pop up in the display. It would be nice if it started quicker like my other apps. The only other issue i am having, and would like to see implemented is option for the screen to stay on longer than my internal phone setting. All issues being said, this is a great app, well worth the money!
Good controls I prefer HP calculators as the RPN system is more efficient than the usual choice of infix. I was looking for another HP calc app as the response of the existing app I had was disappointing and driving me to frustration. This app is suitably responsive. Was pleasantly surprised choosing a financial model over my usual choice of scientific that the model still offered powers and standard form.
Wonderful app, it its really looks like I am using my real hp12, which one I have been carrying arid for the least 18 years =), now I do not need carrying it any more, I do have it on my phone any tike and no extra device to carrying around. I used to carrying around my 18 years old hp12c, now with its app in my phone I still have the accurate of my old calculator but in my phone. More practice and always in my way, and only need one device. Great job, great app.
Excellent!!! One less device I need to carry around. This is an awesome replacement for the real thing. The only downside for some I can possibly see is the short battery life, so just be sure to always have your charger with you if you use it a lot throughout the day.
Best of many I've tried other versions of the 12c and this is the best - clean looking, reasonable size for the fingers, and it works. Paid a little to get rid of annoying pop up ads - it's worth it.
minor bug fix and performance optimization.
