It’s a really good calculator compared to the others I have used so far – though I’d like to point out a few things I wish this calculator had. First of all, a list view of history will be a great addition to the calculator. Secondly, (something that is very important to my workflow) the ability to edit any input from history, plus a cursor to edit the inputs, so that I can fix any mistake from anywhere. Lastly, the ability to perform the nth root of a number is greatly appreciated. Though I must point out, the second suggestion is the most important for me. It’s a great calculator nonetheless; however, I have paid for the full version, and so I expect the developer(s) to add the aforementioned features. I would’ve given it a 5 star review, otherwise.
