I am working on an interesting calculator called minusplus.app ( -+ ). This is an infinite canvas calculator. Where you click anywhere and type numbers, Press space or enter, and it will automatically calculate. You can tag, add comments, and MinusPlus has some great shortcuts, which make it efficient to calculate. I am an SAP Finance consultant, and have to do a lot of calculations daily. And after using this, I can't go back to any other normal calculator.
