This app is just what I was looking for. I like being able use backspace to change a number that I entered wrong. I also like taping on my answer and looking at the history to verify my entries. If I had a number wrong, I can tap on it and change it and continue on from that point. I can clear history at any point or I can keep it running until I’m thru. Or, I can come back at any point later and look at it again until I have cleared the history. This is great, and I don’t know if I have experienced all that this App has to offer. I have been impressed! Thank you developers!

A simple, well designed calculator. Perfect.

My old calc app disappeared so I went to the App Store to replace it. Found all kinds of them with bells and whistles and photo albums and junk. I wanted a good calculator, clean, aesthetically pleasing to look at, functional. Simple. This is EXACTLY right. The other things clutter up something with stuff available many, many places. Thank you for getting back to basics and developing just what, and ONLY what a calculator is supposed to do.

Stop Looking, This Is The One

Clean looking, large, easy to see, and nice to look at. Has a bunch of good extras if you need them like advanced math and several other things. The calculator I was using disappeared one day and I looked hard for a replacement. I really liked this one. It even shows you all the steps you took to to figure out whatever it is you’re figuring. I’d like if there were some direction somewhere.
