HP 12C Financial Calculator App Reviews

It took some time, but with this release HP introduced a retina sharp app, ability to fix landscape and turn on or off the key clicks! Even added a vibrate option.

Does what it is supposed to do. For a fraction of the price of a physical 12C. I now use this as my daily calculator at work. The interface looks good, also on the iPad 3 - even if not full retina resolution yet. Hope this will be updated in the near future. Calculator works in full screen mode, which is not the case with many other calculators for the iPad. An official 12C manual is included in case any help on the functions is needed. A message to HP: please develop an HP50g for the iPad as well!

This app does not work and it is impossible to get technical support. Only half the calculator is displayed and only basic math operations are possible. An excellent example of the shortcomings and frustrations of dealing with virtual companies. No service, faulty software, and no simple way for getting a refund. The HP Way seems to have disappeared. Avoid the hassle and give this app a miss until they work out the glitches.

on the original version of ipad, does not show any functions beyond those of a simple calculator... please fix it, HP!

Pay for upgrade from 1.0 to 2.0

This application is not a 12C it is just a simple calculator that you can download for free elsewhere. Product is not what is displayed.

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 youre thinking of buying this app and you havent used RPN before, you owe it to yourself to spend 5 minutes training yourself, youll love it. Yes, there other free apps that purport to emulate the beloved operation of the HP 12C...and Ive 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!!

I have been using various models of HP Calculators for years. They are by far, the best financial and general purpose calculators available on the planet - the best feature being RPN. Once you have used and mastered RPN you will not ever want to go back to basic methods. Accolades and a HUGE thank you to HP for this App. Finally, we have a superb calculator for the iPad and one that works brilliantly. Worth ever penny and has my highest recommendation.

What a rip-off! I have it on my iPad - it works great - on the iPhone it is a joke - where the hell are the functionality keys! This is nothing more than $2 calculator. Fix this !

This hasnt been updated in ages but it remains a great 12c calculator. I normally use the developers 15C calculator instead, but if you dont need or care about the scientific features the 12C has advantages of its own. Ive used it for years on my iPads and iPhones, up to iPhone 6 and iPad Air 2. Havent encountered any issues, but obviously it is very difficult to exercise the majority of the features this has. It has a great built in user manual which obviously helps with some of the more advanced functionality, but if you are familiar with RPN its more nascent features are intuitive. I havent given it 5 stars as it hasnt been optimized for the different aspect ratios of the newer iPhones. Doesnt affect functionality, though. The default key click sound can be turned off in the iOS Settings; some people wont know to do that and can be put off by the clicks.

Please update it for iPhone 6 ! This could best and only real emulator of a 12c .

This App has NO support from HP. No update for iPhone 5 display! For the price I payed for the branded App I would expect HP to keep this App up to date. Hope HP will read my review!

This app would be perfect if: - Become compatible with iPhone 5 Retina display; - Update when its necessary. HP, update it!!!! plzzzzz!!!

I had this app--or one exactly like it--three or four years ago. It was exactly like an HP 12C in every respect. But then I had to restore everything onto a new iPhone, and all of the financial functionality disappeared. I was left with an, essentially, four function calculator. So I wonder if this is just a technical glitch and the guy who wrote the program is sick/deceased and is not able to read these reviews? That is, maybe hes not aware of the problem. Or maybe he got sued by Hewlett-Packard? But theres something funny going on here for sure. Erase that! I have found that the fully functional HP 12 C appears when you turn your iPhone sideways. Portrait, you have merely a four function calculator basically. But go to landscape, you get the full function calculator that I had a couple of years ago! Sorry about that but it appears other people have experienced the same "lack of functionality."

Bought this app a year ago but it didnt show up in purchased apps when I switched phones, like all the other apps. No contact for such a problem, so they get a one star. Unfair? So is having to pay for this application again.

She is the sole beneficiary

15 dollar app and it wont solve for n. ridiculous. Need a refund

I bought the HP-12C and HP-15C . What got downloaded was a simple 4-function calculator in each case.

Those who are reporting that the full functionality is not there either dont know how to read a manual or are shills for other apps. Works great and I use it all the time.

This app is true to the original EXCEPT for the key click sound! Its loud, slightly delayed from the actual button press, and basically a highly annoying sound. If I silence the phone, there is no feedback to let me know whether it registered a button press, and Im likely to forget to turn the ringer back on when Im done. Update this to a simple, unobtrusive click and Ill give it five stars. I still carry my real 12c everywhere. Edit: Just discovered you can turn off the clicks, but that doesnt solve the problem of no feedback, and the key vibrate is too long to be functional.
