Update ruined the app

This was my go to calculator for the last several years. New version’s design is annoying, and I just don’t understand who would think having the display be a small fraction of the size of the keyboard was a good idea.

Used to be the best

I used this calculator app for years since I have used RPN since the introduction of the HP-35 calculator. This version is now locked in light mode when my phone is, whereas it used to look like the current dark mode. Also, we in the US use a . For the decimal point. So, I suggest you (1) allow the user to pick dark or light mode from the app settings, and not tie it to the phone’s overall dark/light setting, and (2) allow the user to specify . or , as the decimal point indicator. As far as function, this app works great as a replacement for my worn-out HP-41CV.

Useless without instructions

Rendered useless without instructions on how to use this calculator, specifically how to enter data for statistics and regression analysis. No manual in app, and link to author's web site is useless, too. Could not do anything with it
