Awesome Display & Functionality~! RDev Calculator is my Favorite Calculator App & has more Color Choices in the Display, KeyPad and History Tape, (the Expressions and Results and Operators), than any other including the Samsung Galaxy S4. Works Excellent & Accurate. Percent Key works the way you'd Expect it to, {(35+3.39+.77)+9.01% = 42.69, not 39.25} or Change the Order of Operations, a Plus/Minus Button, Parentheses, has just the right Haptic Touch, and a History Tape where either the Expression or the Result or both can be Copied~!
