A Pleasure to Use

Start with a full function calculator that has every mode you might want, including scientific, statistics, trig, binary, even a mode for time and circular angles such as latitude and longitude.
Now add a customizable user interface that is not merely useful, but beautiful, and this wonderful app is what you get.
I especially love being able to easily find different groups of functions by setting them to different colors, like pink for memory, green for trig, and greenish blue for roots and logarithms.
The buttons and number display are very easy to read even on a small iphone.
This is one of my must have apps.
