Fixed a bug that makes things worse

I actually love this calculator, but after the lastest update two days ago, the standard version will not let you type in more than four digits and will go back to 0 if you try to add a 5th or more, it‘s pretty useless now.

Updated Review: They fixed the bug and it‘s back to the great original version. It‘s one of the few calculators I‘ve found that has a back button, enabling the user to erase just the last digit if you mistype, instead of starting over, as well as being able to pull up the calculation history and i.e. take a prior total as a starting point for a new / additional calculation.

This is excellent and easy to use app. Love it

Love this aap very much. It is very easy for use and definitely I like be the lovely clicking sound of typing the number. Highly recommend for daily basis use for office, study, work and teaching.

Great I like it

The notes are good to remember why you made the calculations so you refer back it to it later to do another calculation based on one previously
