HP 15C Calculator for Negative User Reviews

Still BuggyCan’t do basic stuff without hanging. Try 5 Perm 3 for example..Version: 2.1.2

Not updated for iOS 11No 64 bit version -- current app does not work on iOS 11. No idea if it will be updated. (And no confidence as this has not seen any updates in years).Version: 2.0.1

HP 15CDeveloper did a bug fix 3 weeks ago and didn’t bother holding the iPhone in portrait orientation to observe numbers don’t line up with display. Terrible QA. The developer web site (HP) on the AppStore gives an Oops .. page not found. Another QA master stroke..Version: 2.3.2

Can't turn off button soundThis version is an improvement! The keyboard is correct, and the manual works, but you still can't mute the incredibly loud button sounds. This makes it difficult to use in meeting, and frankly gets annoying with prolonged use at any time. Come on, HP fix this issue get 2 more stars!!.Version: 2.0.1

Poor value for moneyHaving forced the perfectly capable open source competition off the app store, how surprising that HP have doubled their app's already steep price. Some minor but glaring problems with the app: 1) I don't want a MENU button, I want an ON button. Thanks for the manual link via the button, but no thanks for the link to your marketing web site. 2) thanks for putting the back image on there, but did you not actually try using it? What would have been wrong with a full-size scaled, pinch-zoomable image? Scrolling it is non-sensical. I still wanted it, and paid, but feel exploited and dirty for succumbing to the desire. If the app had the ability to change into other Voyager models I would feel like I had better value from this premium price — why can't I make it into a 16C or a 12C on demand? Ah yes, HP think they can squeeze a few more pounds out of their iPhone customers. Not from me they can't. Update 2017-04-12 this app has not been rebuilt to be 64-bit and no doubt will completely break in the near future. Cements my poor opinion of this company..Version: 2.0.1

Update needed- and deserved, at this priceGood replica - but not yet upgraded for iPhone6 - nor even ios9. Main screen just a little too small on my phone, with borders in landscape- if it filled the whole screen it would be much more usable. Manual uses old style buttons, not iOS 9. I like it- but was not worth the $ I paid. Next time I'll try a 3rd party copy..Version: 2.0.1

A classicUpdate: It's been almost two years since this app was last updated. It still doesn't make use of the larger iPhone 5 screen. The bug that causes the display to flash after running a program or using the combinations/permutations functions still hasn't been fixed. And, there's still no way to control the key click volume independently. It's a shame that HP seems to have abandoned this app... -- It's great to have an authentic HP 15C on my iPhone. I've been a fan of HP's RPN calculators for years, starting with the trusty HP 25 that got me through college. The built-in manual and alternate portrait layout are nice additions. One bug: After using either the combinations (Cy,x) or permutations (Py,x) statistical functions, the display flashes continuously until some other key is pressed (on my iPhone 4S running iOS 5.1, anyway). Also, as others have noted, the key click sound is annoying to the point where I've muted it entirely. It would be nice to have a choice of sounds or the ability to control the volume separately..Version: 2.0.1

Very Disappointing, waste of my moneyI had purchased the earlier version of the app but they stopped supporting it so I had to pay for it again to download it to my iPad Air. It was expensive enough the first time and to pay for it again was such an unfortunate waste. I had hoped they had improved upon it, most critically adding cut and paste support. Unfortunately no, they had only reissued it due to a digital signature snafu with Apple that caused my version to be obsolete. In fact they had hardly changed the app at all, mostly just to add the phrase "Limited Edition" to the app. Very disappointing..Version: 2.0.1

OK app. But pricey. Needs polishing.UPDATE: HP update this app for screen size and key size! With new iPhones released with larger screens, it is possible to have a calculator app that is practical to use with accurate key entry. However, this app is still small on the larger (iPhone X) screens. Live up to your reputation and don’t let this app tarnish these great calculators. HP has fixed the obnoxious click of the buttons. I'm still waiting for HP to fix this app and it will become my first choice calc. for now its in a folder on page 7. It seems like the "target" area for the buttons (iPhone) is a bit small. I miss the buttons with this app more often than with others calculator apps. It's very close to being great, but these small items keep me from wanting to use it. I can't afford mistakes from missing buttons in my job. Having invested $15, I hope HP is responsive and fixes these items. Until then I have a better, less expensive 48sx emulator with bigger buttons and a viewable stack..Version: 2.1.2

Can’t use the app anymoreAfter an unfortunate auto update, numbers appear below their normal place and is unusable. What are you doing devs?.Version: 2.3.2

HP-15C Limited FunctionalityAfter Apple did the last upgrade to my iPhone5, the HP-15C no longer will change from a limited display of features to a full display when my iPhone is rotated 90 degrees. I have reloaded the app several times without success in obtaining the full functionality. Several friends have experienced the same loss of functionality - how do I obtain full functionality?.Version: 2.0.1

Problem with latest updateI’ve been using the HP15C app for several years now, on several iPhones without any problems at all. Foolishly, I ‘auto-updated’ to version 2.3.2 today on my iPhone 11 Pro Max (iOS 13.3). Now: (1) the numerical display appears below the level of the calculator screen. (2) the reference manual accessed via the logo top right, locks out and doesn’t allow return to landscape view. N.B. I’ve had no response from developer to this post. Nor have I had any response from contact to HP support site. Clearly no one out there reads their reviews, or support requests. Months in from this post I’ve still see nothing..Version: 2.3.2

No Kachunk!!!!!!!!!Why after updating did you get rid of the original key sound? If I wanted an iPhone tap sound I would download any calculator app for free! Please bring back the kchunk sound effect! Please!.Version: 2.1.2

Update please ASAPGreat calculator and HP charged a lot for this. BUT please update it HP so it works with the next iOS.Version: 2.0.1

Rip offIt's not what is being represented none of the functions are even there.... It's so bad.......Version: 2.0.1

Great app, but desperately needs an updateThe app works very well. The only reason I gave 2 stars instead of 5 is to send a message to the app developers to update the app. It will not be compatible with the next version of iOS!! Update: ok, now the app doesn't even work. 1 star. HP, can you please fix?!!.Version: 2.0.1

Programming problemsEntered 122 lines into programming triangle solutions to find that f ISG looping will not program. No SN or Product Number for the App so no access to technical or product support assistance. Pay your money and no support to back it up. Loved my 11c & 15c, for more than 25 years, buy an app and... Well times have changed. Additionally, repeated attempts to report the problem through iTunes Store have failed. Will not accept a report of a problem but will be happy to accept a review. HP sells apps for iPhones but their troubleshooting capability is tied to windows!!! Update: many months later... Nothing from HP. NO CHANGE, no progress, no fix, no attention, no regard for the quality of the product they took my money for. NEXT MESSAGE GOES TO APPLE. BOGUS PRODUCT..Version: 2.0.1

Excellent calculator with bugsI own an old HP12 and am committed to RPN so I am delighted with this App. I do have a problem with “landscape lock” which I think works fine if I have my iPhone free to rotate, but I keep my iPhone in portrait mode. HP15c landscape lock works if I select that first and then set my iPhone to portrait, but after sleep it goes back to HP15c portrait. Fiddly! With such a high-class emulation, it is a shame for a detail to let it down..Version: 2.1.2

Upgrade broke it.The latest upgrade broke it, on my iPhone 11. The numbers are now out of place in both orientations. Please fix...!.Version: 2.3.2

App no longer has large enough characters after last updatePaid $45 each for HP15C and HP12 apps in the store (!). Last update made numeric characters and icons on my iPhone XR far smaller difficult to use in HP15C app, both simplified and full versions. HP 12C still OK. Called HP support, tried the web support page used for my other HP equipment purchases, got someone in handheld calculators who sent my message into the bit bucket, 2 months later, several reinstalls, not fixed. it appears the apps are orphans in the giant HP system. Too bad. I have an antique irreplaceable real HP15C which eats batteries which I don’t wish to destroy. Hopefully someone at HP or Apple flags bad reviews, sends a smoke signal to HP who will take action..Version: 2.3.2

Complete rip offHaving bought one of these and found it change from an HP15C clone into effectively a cut down normal calculator without any of the HP15c features, I reckoned HP were ripping us off in order to force us to buy a new version. The new one however is exactly the same. What a rip off. Can't believe Apple let them get away with it..Version: 2.0.1

Fix this pleaseThis is a horrible mess. I am stunned that HP, a company long known for quality hardware, would let this appear on the App Store. When subroutines finish executing the contents of the x register flash endlessly on the display. The only way to make it stop is to press some key which of course changes the contents of the x register and pops the stack! For a while, pressing the function key f then prefix would lock up the calculator, displaying the mantissa, instead of timing out after one second and returning to a normal display. Now it’s ok. So that’s going to be an intermittent bug. But come on, people. Just fix the flashing subroutine result problem. Where do I go to get my $15 back?. Retro 15C works just fine and it’s free..Version: 2.1.2

Needs updating - no longer worksI used this app daily until I upgraded my phone to iPhone 13 Pro and IOS 15 and now the app doesn’t work anymore. Won’t open, just reverts to the iPhone Home Screen..Version: 2.3.4

Great in landscape, buggy in portaitGreat calculator direct from HP, all the same algorithms as the original and it includes the manual. The portrait version, which is a nice touch to include, could be a lot better though. On the iPhone XR the digits aren't in the display area at all..Version: 2.3.2

Please update for iOS 11!!!Please update for iOS 11!!! I paid for this expecting it to be well supported. It works on my old 5C which is now, apparently, my calculator..Version: 2.1.2

Not as advertised - limited functionalityFalse advertising, does not have functionality supposedly paid for. Very disappointed, can you return apps and get money back?.Version: 2.1.2

We need this calculator updated!I’ve been using HP scientific calculators for forty years. The only HP15 I trust is the version offered by HP, but they haven’t updated it for IOS11. When will loyal HP customers’ needs be addressed?.Version: 2.1.2

Pretty, powerful, some bugsThis is a full-featured and good looking emulation of my original and beloved HP 15C Scientific RPN calculator (I still use a Limited Edition version today). That said, it’s a little buggy in annoying but harmless ways. For example, in portrait mode, the displayed numbers aren’t actually positioned in the display (on both iPad and iPhone). And results from running or numerically integrating a programmer function leave the displayed numbers in a flashing state..Version: 2.3.2

All good on iOS 14.3Have used 15C on iPhone 10 for over 2 Yrs, with no issues. Upgraded to 11pro with 14.3, so far no problems👍.Version: 2.3.2

Fails to copy and pasteThose absolutely isolated the HP calculators from everything. Why can’t we copy and paste to and from their digital calculators? Maybe it can and I am just ignorant as to how? I’m a HO-41c users from forty years ago and it is still my favorite! It is so fast! But try getting the result from the calculator to anything else and you are stuck!.Version: 2.3.4

IOS 11 issueApp does not work with ios11. No update available.Version: 2.1.2

The advertisment for this app is misleadingI downloaded and was charged for the iPad version of this app. I need a scientific calculator. The version for the iPad lacks trig and other scientific functions. I wouln NOT have wasted my time and money on this product, if it had been obvious that the iPad version did not include trig functions. This application is worse than useless. There are many free calculators, if all I wanted was to do arithmetic. I would rate it less than zero, if this were possible You should be ashamed for selling such a poor product.Version: 2.0.1

Numerals are not located correctly V2.3.2In portrait mode, the numerals that are displaying are showing up about 40% in and other 60% outside the “LCD” display window, on the metal frame. This bug just arrived with Version 2.3.2 running on an XR and iOS 13.3. It is just the numerals that are not located properly, the “hardware” looks OEM. In landscape mode, the white Apple line across the bottom to drag up to switch apps is now persistent and in the way of the STO, RCL, ENTER and 0 keys. In landscape mode, the numerals are smaller than they have been and are supposed to be..Version: 2.3.2

Display flashes?Now that the calculator division is under “new management”, could we please get an update to stop the display flashing? Write a simple program. Run it. Display flashes. Even just pressing R/S. This is not how a real HP 15C works. 15C is still an amazing calculator, just wish implementation on iOS was done a little better, a little more care taken, especially by the company that designed and produced it..Version: 2.3.4

Great but long in the toothThis is my go to calculator, I love using it. But it has not been updated in 4 years now. It needs some attention before it can be called great..Version: 2.0.1

Not iOS compatibleLove the calculator, but HP has not (and appears will not) update the app for iOS compatibility. Very, very disappointing in that it's an outstanding calculator and app to begin with. This speaks volumes about HP and their "concern" for their customers and clients. "Come spend your hard earned money with us, and we'll dump you the first chance we get." They say it's the little things in life that make a big difference. After this lack of concern for their customers I'm completely disinclined to purchase any HP products going forward. If I were in product development at HP I'd be massively embarrassed. Shame on you..Version: 2.1.2

HP 15CI had spoken with Apple, who in turn asked me to ring the Developer. Spoke with HP Support, sent them images of the numbers not lining up with the display window, was told that they were aware of the problem, but it was up to the Developer to make the fix. That was almost a year ago, and still it has not been fixed. Paid for the app, would expect bugs to be fixed as required. Apple should remove this app from the app store..Version: 2.3.2

Abnormal for HP productThe digit are not in they’re place on the screen of the iPhone X plus.Version: 2.3.2

Ripped off!Strongly object to having to pay for this app again, having paid a lot for the 32 bit version..Version: 2.1.2
