Size adjustments for iPad 4/5
By QuickTake 100
Would be nice to have the full-size 12C when used on an iPad in portrait mode.
HP 12C app 1/5
I have on my I phone but it will not go to financial view when I rotate my phone.. I just purchased again for my wife’s phone got it downloaded and I still have the same problem. You said you had fixed this app a year ago but apparently not.. I have now paid for two applications that do not work...
Not very good advertising!!!!
HP 12C 1/5
By Treece J
The calculator I got is not the one advertised. How do I get my money back?
Hp 12C still not functioning on iPhone X 1/5
Hp 12C is still not functional on iPhone X other than as a four function simple calculator. Rotation for the financial functions. The developer is very remiss in not providing proper updates. I’m now carrying my original 12c device the avoidance of which was the reason I purchased the app in the first place. Apple should take all HP calculator products out of the store until these issues are fixed for those of us who have already paid for a non-functioning calculator app.
Outdated and no updates 1/5
If you are using a reasonably modern iPhone, which has no “home” button anymore, then the only way to switch apps is to power down your iPhone. It insists on going into full screen mode and never relinquishes the screen.
Outdated, outdated, outdated. This is an orphaned app.
HP 12C Good but not supported 3/5
Good app. Looks and works like the actual HP 12C. Does not display full screen on iPhone 6, and most likely newer iPhones. This should be a simple update considering the price, but has not been updated in a year. Would also be nice to display full features in portrait mode. There are less expensive and free competing apps available with these features. I wanted to support HP. Too bad customer experience is not a priority.
HP 12C The Best! 5/5
Superb software reproduction by HP of its original outstanding HP 12C pocket calculator! Works well on iPhone XS Max and iPad Pro 11” with iOS 12. Thanks HP, well done!
Short lived perfection 2/5
Loved the app for 2-3 weeks and now can’t get screen to rotate. Have deleted and reinstalled to no avail. Pls update w fix. Thx.
Won’t rotate to landscape on iPhone! 1/5
By Commercial Appraiser
Purchased this on my employer’s iPhone 6 after using it fine on my iPhone 8 Plus. He paid $14.99 and it won’t rotate to landscape to give him all the financial functionality. We are both long time 12C users. Very disappointed. Is there a solution to this HP? Thanks
Love this app, but... 5/5
I love this app, because it’s just like my physical calculator, which I use every day. However, I bought this $15 app on iTunes, and now I’ve switched to a Samsung Android phone. Do I get access to my already-paid app from iTunes on Android, or will I have to pay another $15 or so to get this on my new phone? Thanks and happy holidays!
Landscape functionality does not work 1/5
I am unable to see all the calculator keys when I turn my phone horizontally (landscape). Bug has not yet been fixed.
Doesn’t work with voiceover 4/5
Fine app , but not recommended if you’re blind. Need a refund
By Gina & John
Disappointed before the app finished downloading. App Store said $14.99 but HP charged me $42.78. Doesn’t bode well for a financial calculator ...
HP 12C 5/5
By Scott - frustrated 2018
I just downloaded (August 2018) the HP 12C App on my iPhone and I don’t have access to the full screen and functionality. I didn’t realize I had my screen on lock mode. All is good.
Excellent Calculator 5/5
By Not dependent
This makes it easy to have a full HP 12c on my iPhone and iPad. If you want pure HP 12c, it does not get better than this.
I would like to see an HP 19BII app for the iPhone and iPad. I prefer the 19BII over the 12c since the 19BII has a back button, solver mode, better placement of the enter key and a multi-line stack display as part of numerous improvements over the 12c.
For the physical calculators, my 30 year old 12c is still in use. My 28 year old 19BII has a cracked battery cover and the display is questionable. It would be great to have the 19BII re-incarnated as an iOS app. Until that day, get this 12c app.
Screen rotation 1/5
Worked great at first but now the screen won’t rotate to be able to do financial calculations which is the whole point of buying this app. Very unhappy. Uninstalled and reinstalled the app many times no luck.
Total bust 1/5
I am a 12C calculator fan but this app is a joke. It just gives you basic functions like any calculator. Doesn’t rotate to show all functions and provides no way to contact author. Save your money!
False advertising 1/5
The picture of the HP12C shows functionality that is not in the app. How do I get a refund?
Doesn’t work on iPhone X 1/5
Doesn’t rotate 1/5
Screen Rotation 3/5
I still have a problem with screen rotation despite having deleted the app and re-installing.
Freezes on IPhone X 1/5
Have had app for several years and it worked great. With upgrade to IPhone X, app freezes after launching every single time. Needs update.
Can’t get landscape on my app? 1/5
Not useable for me in portrait mode. How to I fix?
App doesn’t work! 1/5
Beware. App doesn’t work at all. No customer service.
Stopped working 2/5
The latest fix was for the HP12C app to fix rotation on the IPhone. It was working before the update but has since stopped rotating after the update. Found that I needed to fix rotation to landscape otherwise it’s just a money calculator since only 2 place decimal. Apple iPhone 6s now updated to IPhone X. Wife’s iPhone 8 upgraded from iPhone 6 works fine. Perplexed
Zero stars for iPhone 1/5
This product is a simple calculator on iPhone. DON’T BUY IT. IT HAS NO FUNCTIONALITY & impossible to get your money back!!!!!!
Almost great! 4/5
By Ntb Atlanta
I had a knock off HP 12 C on my iPhone for years. With the recent update to iOS, it stopped working completely. Just added this app from HP. So far I love it.
One small complaint is there is a shadow on the numbers on the output display. i.e. the font that is used in the outlook display was design to create a slight shadow effect. The resulting effect is that it makes the output slightly blurry. Most people probably won’t notice but as you age and numbers/letters aren’t quite as crisp, it becomes annoying. Not sure why HP decided to add the shadow effect but it would be nice if could be eliminated or at least turned off.
Overall, a good job!
Won’t work-needs update? 1/5
I bought this app a few years ago and now it won’t open. It tells me it needs to be updated to work with IOS 11. But the specs say it works with iOS 8 and up. What’s the deal?
Consistent With Expectations, However... 2/5
Please get rid of the screen rotation. I don’t want to be forced to physically rotate my phone to landscape view in order to use the advanced financial features of this calculator. I don’t know why it displays a simplified calculator when I’m in portrait mode. If I wanted a simple calculator, I’d use the native iOS calculator included with my phone. I purchased this because I wanted something that replicated the 12C I physically own. Or better yet allow me to lock the landscape mode in the calculator settings. It looks like people have consistently left this comment for 4 years! I’m down grading my rating to 2 stars!
App is working on the latest iOS 5/5
I got warnings from iOS that app may not work with the latest iOS, but it works, so I’ve updated my star rating to five)))
Works great. 4/5
Works great. If you are a 12C user and you need one on your iPhone this is a good value.
What’s not to love? 5/5
With the latest updates, the bugs that people complained about are gone. This is app is the next best thing to the real deal.
Poor support 1/5
You would think if HP put their name on this and cared about their brand they would provide more support and relevant updates. Around any major ios ipdate - surprise! - planned obsolescence rears its head and functionality tanks. HP should be committed to excellence and not mediocrity. Having a non functional app and a 3 or lower star rating - is that part of your corporate values??? well HP you are not really winning customers or adding shine to your reputation...
HP 12-C 3/5
Since you updated the app for the iPhone yesterday to fix an issue on screen rotation, I can’t rotate the screen anymore. How do I fix that? Before you updated the app, screen rotation worked perfectly. It now works in portrait format which is much more limited than landscape. I can’t get it to rotate to landscape now.
HP 12C 64 bit 5/5
Updated to x64 and works like a charm!!!! Thank you SO much!!!!
Any updates for iOS 11, with 64 bit architecture? Resolved!!!
Ótimo! Atualizada a versão para iOS 11 5/5
Parabéns! Após reclamação foi Atualizada a versão do Aplicativo para 64bits iOS11. Agora posso continuar utilizando a original HP 12C
Update: No update since 2012? 5/5
Hey HP, are you going to update the app? Got a weird (intermittent) message from iOS 10 about compatibility issue. Unfortunately I didn't jot it down.
Update: now that my iPhone is running iOS 11 this too expensive app is useless! 😡
Update 2: with the new 64-bit update, I'm once again a happy user of this app. ❤️ I swear I can't use the "regular" calculator anymore!
Needs an upgrade 3/5
I purchased this after I received a message that the other HP 12C would not be compatible ... sorely needs an upgrade for iOS 11 compatibility
**update: everything good now, with the app, it’s now compatible with iOS 11. Upgraded the review, but would have wanted a bit faster compatibility to iOS 11 (e.g., from the start)**
Recently updated for iOS 11 5/5
The app was updated recently. It is now fully supported and reliable.
Click sound, and soon to be obsolete 4/5
UPDATE: Updated to 64 bit, and changed Key clicks to iOS default. Works fine now.
UPDATE: I'm so glad I paid what was already marginally too much for this app, and it will become useless tomorrow. Thumbs down to HP!
UPDATE: I'm changing my rating to 1 star until HP updates the app to 64-bit architecture. I use this app daily in my financial business (when my hardware 12C isn't handy) and I'm worried about losing access to this (expensive) app when iOS 11 rolls out. It seems that HP charged an arm and a leg for this app, then abandoned it.
This app is true to the original EXCEPT for the key click sound! It's 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 I'm likely to forget to turn the ringer back on when I'm done. Update this to a simple, unobtrusive click and I'll give it five stars. I still carry my real 12c everywhere.
Edit: Just discovered you can turn off the clicks, but that doesn't solve the problem of no feedback, and the key vibrate is too long to be functional.
Expensive app and values don’t show in window 1/5
I just bought this expensive app as I love the HP 12C. Shocked to see the numeric values aren’t even in the proper window in landscape mode. Wow.
LOCK ON SCREEN PROBLEM IOS 11.0.2 2/5
Landscape does not lock on since IOS 11.0.2 released
No updates for IOS 1/5
Had this app a month and now it is obsolete! HP👎
Need Updates!!! 1/5
I use this financial calculator in my business. I was a mortgage loan officer for 14 years & I've been a Realtor for the last 7 years. This calculator came in handy when my clients wanted an idea of what their house payment would be. I started getting pop up notices with IOS 10 & now it won’t even open with IOS 11. I’m disappointed with HP that they would charge a high price for this app & then forget about it by not developing updates. There was one update a week ago for 64 Bit Version, otherwise, the last update before that was 5 YEARS ago!!! I still have my original HP 12C, but it’s not convenient to carry with all the time. Come On HP, Get With The Program!!!
Please update! 5/5
I purchased my beloved HP-12C in 1983 and it still works like a charm. Love the iPhone app and thanks so much for the 64-bit update!
Great app 5/5
HP calculator user since 1980 (34C), great to have the iPhone version. Happy that HP updated it to 64 bit finally! :-)
Doesn’t work on iOS11 1/5
Should issue a refund if the product will not be supported.
Settle down it's been upgraded. 5/5
Works great as always.
Doesn’t work in iOS 11 5/5
C’mon, HP. Update this already!
