Wow! Great Calculator

Wow! This is a great calculator! I don't know how people use the default Apple Calculator.

The big difference? This has a tape so you know you didn't mistype any number. It's like using a business calculator but works like a regular calculator.

I love the default color scheme and the tape on top of the calculator in portrait mode and the tape on the left in landscape mode and the rounding to 2 decimal places and the 00. The rotation from portrait to landscape mode is kind of neat.

I wish Apple would allow you to change the calculator that opens from Control Center.

Calculator Widget for iPad

Finally, an easy way to open up a calculator on iPadOS.
On iOS, you can pull down the Control Center and you can have the calculator there and get to it easily.
On iPadOS, however, there is no default calculator app, so there is no way to get to a calculator from the Control Center.
Come along this app that adds a widget (albeit an extra purchase). Now you can get to a calculator from the widget handy by swiping right on the home screen. The best thing is that you don’t have to open the app and you can simply do your calculation from within the widget itself.

The only reason that I’m giving this three stars, is because the calculator widget doesn’t work if you pull down the notification and swipe right to get to your widgets. It shows up, but you can do anything with it. But that’s when I need it the most, it’s when I’m doing something and need to get to a calculator to do some quick calculations. I can always get to the calculator by going to the home screen first, but that defeats the purpose of purchasing the widget add-on.

If this gets fixed, I will definitely upgrade the rating to 5 stars.

Dual-line arrangement VERY useful

Compared to a financial, algebraic, RPN calculator I use every day, this is simpler. So far, I have not performed algebraic functions, only simple math.
It displays concurrently the entries which have produced the answer shown. Great for a visual check of the entries as you recall inputting them! Most helpful ;-)
