I’ve been using this app for many years. It is one of my daily go to apps. No exaggeration. I use this every single day. If you’re familiar with the HP-12c, you’ll be completely familiar with this. I’ve never had a problem with it. It just works.
A special shout out to the developer. Years ago, they gave the app a new, sleek, flattened look. I wrote to them about the fact that, due to my vision, I couldn’t see the demarcation of the buttons. The developer restored the original look as an option, which you can find under settings. Thank you for maintaining that.
Some may be put off by the unfamiliar way of doing a simple calculation using what is called RPN notation. In school we learned PEMDAS-based arithmetic notation to enter numbers for calculations. Try spending a little time learning RPN. It helps get rid of parentheses and you control the order of arithmetic operations. It’s better for any multi-step problem other than adding a simple column of numbers.
