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~!

This is an ordinary caculator with all the usual, necessary functions one would expect and without unnecessary clutter. But particularly useful is the FUNCTION key. Set any calculation or macro into the function memory and it remains there for constant use. So, set a currency conversion for exchange from JPY to USD (= x / 78) and all you need to do is enter any amount of Yen and it tells you instantly the USD value. Great for shopping abroad.

Promising calculator but some usage aspects of this app let it down. After trying several apps like this there are a few that are better like MemCalc but... MobiCalc Free is tops for me so uninstalling this.

I've been looking for a calculator that suited my needs (basic) and also had a "tape" type of feature. Love the options to change looks! Wood theme!
