HP 15c Calculator

I grew up using HP RPN calculators through high school and college. Regular calcs have never felt right after that. Very happy to have found this app. Works just like the originals. Very pleased with the latest update that adds a vertical layout now. Almost feel like I have my old 41CX in my hand again.

I’ve used HP 15c for many years because I missed my faithful college companion, and it’s nostalgic and fabulously functional. But the advances in the latest updates are nothing short of amazing. Addition of functionality in the portrait view is top notch…thank you!!! I have a lot more to explore if the What’s New list is accurate, but immediate reaction is 👍🏽 🥰!!!

This is my favorite calculator ever so I can’t give it anything but five stars. There is another (unofficial) 15C emulator that disables the home bar unless you swipe it twice. This avoids accidentally swiping the home bar instead of pressing a button on the bottom like “0” or “.” That small addition would make this perfect.
