HP Prime Lite 4+

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!

This is a great app, I love the RPN mode. Once you go RPN you will never go back. I just wish the app had optional skins and layout profiles for the keys. I want all the new features and functionality, I just wish the layout and color scheme could mimic the old 48G. I still have my 48G and I tell my kids that have to use the super fancy new TI Graphic Calc for school that “some day you will get a real calculator, like an HP, that can do RPN”.
