HP 12C Financial Calculator app for iPhone and iPad

I bought this app more than 2 years ago and never saw an update. weird...

Works exactly and looks exactly as the real thing. Couldnt be happier! Ive had it for over a year on my iPhone and iPad and I dont think Ive carried my actual calculator since. My iPad makes the numbers bigger, easier to go even faster on it for quick house payments for clients. I would buy it if youre on the fence. Last one youll have to buy!

At the time of writing this review I am currently studying elements of Bond Pricing & Duration. I have a physical HP 12C Platinum that I left back in my room by mistake, so I downloaded this app. So far its just like using the real thing (although admittedly I have not performed any complex computations). My one suggestion would be to update the apps resolution to that of the iPhone 6-7/iPhone 6-7+ native display resolutions. On my iPhone 7, there are black bars on the left and right hand side of the screen (when held horizontally) that are somewhat irritating. Surely this fix would not constitute a large undertaking for Hewlett-Packard 4/5

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!

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!!

The app doesnt allow to change the decimal separator from comma to point.

Shame! You destroy a brand by slacking off on updates. My phone is unstable because of this outdated app but I rely on the 12C daily. Update it or pull it, just dont further frustrate those who have been HP fans for years.

HP has abandoned the app. It fits to the old iphone 4 size screen. You deal with black bars if you have a 6 or 6 plus. I did see that 2012 was HPs last attempt to update. Too expensive to be orphaned.

This app Disappear from my iPhone , rarely used it , I payed for it . Give it back . Check your data base you will see that I payed for it,

Why hasnt HP updated this app? Do I have to contact Meg Whitman to get this app the attention it needs? Cmon!!!

Last update was in 2012? As I use the app now I receive a message for App Store about that developer needs to update the app for continued performance Common HP, update the app!
