HP 15C Calculator Reviews

App no longer has large enough characters after last update

PenroseInverse

Paid $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.

Trig function not working

WB4...

I needed to compute an angle for some survey work yesterday, simple right angle trig. To my surprise the app returned garbage for the arc functions. I confirmed against a real HP 15C and other calculators and the results are meaningless. Please check this out and fix this major bug. Thanks Martin Update: I did further testing today and it appears the inverse trig functions return results in radians always regardless of the angle mode: degrees, radians, or grads. Should be a simple fix. This only occurs in complex mode. It works correctly when flag 8 is cleared. Perhaps this is by design.

Requires Update

Update: New: the display numbers do not line up in the display properly Now I get a message that this app soon will not work in future iOS versions unless the app is updated. The developer website, HP, is of no help. I like this application, but my iPhone is generating a message that reads that the app can have a negative impact on the performance of the phone unless it is updated.

Why can’t my wife access her app

My wife has shared this app with me, all of a sudden it says this app is no longer shared with you. Why? Have used hp calculators forever.

Misplaced numbers render unusable

I used to use this all the time. Since getting a new phone, however (iPhone 11), the numbers appear below the spot where they should in portrait mode. Please fix. In the meantime, I recommend PCalc as a good replacement.

Latest Version 2.3.2 Broken

On an 11 Pro Max, running 13.3.1, portrait mode does not even have the calculator display numbers fitting in the UI...they appear below the background display graphic and sit just about the top calculator keys! Ugh...how about a little Quality testing folks?! This is obvious on first launch for Pete’s sake!!!

HP 15C

Superb software reproduction by HP of its original outstanding HP 15C pocket calculator! Works well on iPhone XS Max and iPad Pro 11” with iOS 12. Thanks HP, well done! Latest update portrait mode displays numbers outside the window.

V2.3.2 creates bad graphics

B D Something

Great app - I’ve been running it for over 4 yrs!! However the last update messed up the graphics - as the numbers are no longer shown in the register, just summarized at the bottom of the screen. It’s too bad - as the calculator seems to work fine - just a bad graphics patch somewhere. Please FIX!

Problem with the latest update

JDJD66

The numerals appear below the display window on the iPhone version in portrait orientation. It does not happen in landscape orientation or on the iPad version. Please fix ASAP.

App is true to the original, latest update caused display issues

OttersRock!

I don’t know whether it’s related to an iOS update, the latest (2.3.2) app update, or a setting on my phone (iPhone 11, 13.3.1), but the font size has been reduced on both the landscape and portrait views and the display numerals’ location has been moved out of the display area on the portrait view. Please update the app or advise potential causes and solutions to this problem. Thank you!
