We are aware that iPhone comes with a native calculator, but we must ask: when the result of what you are calculating seems strange, what do you do?

Most people say they repeat the operation. But what happens if you, once again, have the same result? Do you triple check? What happens if the result is different on the second or third time? How can you be sure which result is correct?

We present you CalcB! CalcB is a basic calculator with an interesting feature: your operations are shown in order for you to confirm there were no typos in your calculations!

In addition to this awesome feature, CalcB has other operations that are unavaible in the a free native calcutor, such as percentage and square roots!
