Customer Reviews

Helpful with basic calculating needs

I've had this app for quite awhile now. It meets my needs for a basic calculator but do wish it had a % function (Ex: 50 + 23% = x). A couple to things I really like it the ability to change font sizes and the 'paper tape' that makes it possible to proof the figures you've entered. It is especially helpful to be able to email the paper tape to yourself for archiving purposes. The calculator fills up the whole screen which makes it easy to see and enter numbers on. Overall, a very helpful app. Thanks.

Big Calc. Big Productivity

I use this on my iPad and find it very useful for the majority of calculations
I do. The PAPER TAPE feature is extremely useful and eliminates the need for
A standalone adding machine. Also like the size... It works great with the iPad.
Just the right amount of features and very streamlined. Highly recommended.


Never had any trouble, 6 years of use, and the fact that I can flip it on the iPad and run a tape is great. I love this app! I agree, it would be so much better on the laptop if they made a Mac version, this is way better than the desktop calculators. This one works like a real calculator. Yay!
