Wow! Great Calculator

The Guy Behind The Guy

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.

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 ;-)

Great app


I've been using the app for about 2 weeks now and haven't had a problem so far. I don't use it for complex calculation so I can only speak to the convenient features such as the ability to see previous calculations. Love the layout and look. Great app!
