### 5/5 — Perfect little calculator

*2020-02-27*

Does everything I need it do, and little else, I love the simplicity!

I think the only thing I would change is perhaps having the ability to swap the + and = locations. I like this layout on a 10-key but on a phone the = being in the lower right is so ingrained in muscle memory...
