Calculator HD Pro

iPad doesn't have a bundled calculator app, so this is perfect.

Love this app. It is simple to use, clear graphics, great big calculator sound and you can see what you have entered scrolling across the top.

This app has all the functions I want but takes bout 10+sec to start on my iPhone 4S. Prob not gonna use this Calc app until they improve on the start up speed.

New landscape mode is a big improvement. Developer very responsive to suggestions for improvement.

The Calculator HD Pro has a good history function and has a scientific calculator option. You can also change to one of several color schemes. Most importantly, it also has the three features that I look for in a calculator, and they are remarkably hard to find in Apple Store calculators: 1) when I hit the equal sign repeatedly, it repeats your last function. For example, if I enter 10 + 12 and then hit = repeatedly, the calculator will continue adding 12 to the sum every time I hit = 2) the ability to view and edit a function as you are entering it. For example, if I enter a function adding and multiplying 20 different numbers, and then I realize that I need to change + to * or add a parentheses, I don’t need to reenter the whole equation—I can edit! 3) you can recall a function from your history tab and edit it to tweak your equation! Big time-saver. I don’t love paying for apps since I’m a long-time android user, but if you use your calculator as much as I do, this app is worth it.

How do I start with a negative number? I use the +/- button and it changes the number.

I use this calculator everyday…..

I tried to delete a list in history tape. It will not let me. And emailing support does not work because the link is broken.

Flawless App that has become “family.” It’s that darn good.

Seeing all calculations and the ability to backspace AND save all calculations makes life so much easier. Helps to turn anyone into an organized accountant!
