HP 12C Financial Calculator App Reviews

Comma separator

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

Never i saw a update

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

Lazy on updates

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 My phone is unstable because of this outdated app but I rely on the 12C daily.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.

Works great for my Mortgage team

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!

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.

Rip off

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,

No update since 2012?

Hey HP, are you going to update the app? Got a weird (intermittent) message from iOS 10 about compatibility issue. Unfortunately I didnt jot it down.

Not updated for iOS 10

There is an error message ever time the app is opened stating the developer needs to update the application.

Could someone update this app, please?

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!

New HP 12C app is TERRIBLE!!!

I LOVED the amazing non-official 12c app I had and lived for years. Now that app has disappeared mysteriously from my phone and I just spent $15 to buy the official one from HP. Unbelievable how lame it is. HP should be embarrassed. This is indicative of crappy thinking and lame products at HP. Why they are going down the tubes as a company. So so lame.

Functional, but could use small improvements

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

Needs Update

I loved this app until iOS updated and the developers did not keep up. HP needs to update their app to work with the new OS, esp for what they charged.

Miss my prior hp app

This calculator functions just like the other app but not as user friendly. The click sound is so annoying and you can only shut it off. You can only use the app in landscape. Why didnt hp hire the same developer of the old knockoff? It was the best! Even better than my actual hp calculator.

Theres a Mathematical Error in this app!

If you enter a number with more than 10 digits, the program automatically inserts a decimal after the 10th digit. Subsequent calculations are thus in error.


KEEPS CRASHING WHEN OPENED. I receive a message when app is first opened stating "developer of this app should update it since it is slowing down my system". Presumably this is an iOS message, but is concerning.


Where is the update so we can have full screen no iPhone 5S???

Complex problems doesnt work

When you arr trying to do complex problems, the calcularor doesnt work... Eternal running

No landscape mode

Since I upgraded to my iPhone 6, there is no landscape mode - rendering the finance functions inaccessible. Please fix!

It works but...

It doesnt fit to the iPhone 4.0 screen size, which have been on the market for a while. What should I expect when I open it on iPhone 4.7 or even 5.5? Come on HP fix it for us :) !
