iPhone XS resolution

The calculator app is very nice to have in my pocket as a decent RPN calculator with all of the CAS features, etc. I wish that the calculator would be updated with a taller resolution with smaller margins on the sides as the iPhone XS resolution better matches the dimensions of the HP Prime. The zoom-out animation at app-boot-up shows off what it could look like. I feel that the keys could be bigger and easier to use because of this too.

I installed this app on my iPhone 8 Plus running iOS 12.1.2. The app periodically crashes. The first time it crash, I was testing the draw command. And With the first line drown, it crash. The second time was when I was entering the example on page 14 (36 deg, 40 ‘ 20”) of the main user manual. It crash when I enter the 20 after the 40. The calculator is nice and looks powerful ( meaning it has a lot of potential) however, hp needs to update the app. I am sure hp engineers have this app running on the new iPhone, then I am sure it crashes as well. Or maybe they just can’t figure out the problem. I hope they can find a fix so I can make purchase. But then again will it be good idea to buy an from a developer who only update the app wince a year? Good Luck!

Why isn’t the calculator larger!? App needs an update!!

Excellent, except for the fact that the calculator is a little small. I’m using an iPhone XS Max and there is plenty of empty space around the calculator that can be used to make the calculator larger, which makes it more usable. This kind of stuff frustrates me. The app should be optimized for my iPhone. Instead it’s optimized for an iPhone 8 or earlier. I want to buy the pro version, but I’m not paying for it until this super annoying issue is resolved.
