Best Calculator on iOS

Not only is this app beautiful, it's also highly functional. After searching through what must have been 20 calculators, I was ecstatic to discover this one. The developers are also very friendly and responsive, incorporating several suggestions into the app. I highly recommend this calculator!

Very nice

Not often I find a calculator on iOS with modulus built in, works as advertised.... its a calculator, and it’s free

Great calculator but please fix the percentage error

This is a calculator I looked for a long time. It has a very nice design. However, can I you fix the error of %. It shows error when ever I use this button. Thank you again for the app.

Developer Response ,

Thank you for your review and your constructive feedback - we greatly appreciate it. The % key is meant to to be a modulus key, not a percentage key. We tried our best to make that clear by having the calculator output "mod" after pressing the % key instead of "%," so we apologize that this has been a source of confusion for some users. Because it isn't a percentage key, using it like a percentage key will generally result in the calculator displaying "error" (as it should). We hope that clears it up for you - sorry again for the confusion.
