All in One Calculator

I have been searching for a programming calculator for a while and have gone through quite a few apps before finding this one. It does everything I have been looking for that other apps lack. Being able to look back on calculator history as well as comment on operations is a feature I didn’t know I needed, but has come in use multiple times. The unit conversion has more units than I have seen in any other app and shows all units converted rather than having to pick a 1:1, which is very handy for quick comparisons. The developers are also very helpful and quick to respond.

This calculator truly is a one stop shop for all my calculating needs. Though it offers so many complex functions, the interface is user friendly and easy to work with. I especially love that I can record my answers for later use. 2020 was a crappy year so it’s great to have a straight forward high functioning reliable calculator.

I was looking specifically for a RPN calculator that also has unit conversions. I use these functions daily. I downloaded and tried many calculators but something was always not right with them. Then I found this app, it works great! Absolutely the best I have used. And to make it even better there was a small annoyance I contacted the developer about. He agreed to fix it and the fix was in the next release. Just wow! Thanks for making this app available.
