The arrow navigation key lags
The arrow navigation key lags a lot, you have to press it multiple times before it register and moves around. Specially when I input a long equation and make a mistake somewhere it’s a nightmare to move around to that variable and correct it. Im using iPhone 13 pro.
Good RPN calc, doesn’t fully use screen real estate
It’s been a while since the app was updated (2y) so perhaps it’s been abandoned, but it would be good to see an update that zoomed the interface to make full use of the iPhone screen. Right now there’s a lot of wasted space on the borders which makes the calculator needlessly small and hence quite difficult to use.

Great RPN emulator for numerical calculations
The title says it all and it’s free.
Wasted Margins
Like others have said, this app needs to be updated to allow it to be zoomed in (permanently). There is wasted space all around the edge, causing the buttons to be smaller than they need to be.
Needs an update!!
Update the app, please. Among other changes and updates, this needs support for modern iPhones and iPads. This app needs some attention. What a joke.
Needs to stop wasting screen real-estate
I gave the lite version a try and like the features. Heck, I’d gladly pay for the pro version.
The one thing keeping me from getting the pro version are the huge blank spaces all the way around the interface.
For now I’ll stay with the 48G app.

One bug.. otherwise brilliant
I have the real HP Prime, which is just astoundingly good at all the things I needed at undergrad Math, Physics, and Electronic engineering.
The FREE apps for iPhone and iPad are almost as good as the real thing, and outshine every other graphing calculator app. Of course, they all have steep learning curves, and when you’ve learnt one it’s natural to prefer it...
However, the free iPad version of this HP Prime app in April 2021 has a bug - it won’t graph simple functions. Just try it with an x squared function and be amazed at the horizontal graph line instead of a curve!
Bizarre, because the iPhone version graphs properly.
Thanks, HP, I’ll keep using the iPhone version with my little finger and extra reading glasses until you can fix the iPad version!

Great Calculator
It would’ve been a 5 star if they could update the interface to take advantage of new phones display. As of now a big chunk of the screen on the top and button is just black.
Add skins
Make the app customizable!! Great calc though!
Powerful
5 for easy working with complex numbers,
5 for easy work with mixed different units
5 for accessibility,
5 for easy define of functions and use of them
Good for electrical engineers
Only may need a big screen
