This is a tool to help you for making decision which one is cheaper.
When you go to the grocery store or shopping mall, you may find the same products but different quantity. One costs $0.99 for 1 lb, the other costs $3 for 4 lb. It's easy to say $3 for 4 lb is cheaper. But how about this: $2.35 for 1.5 lb vs. $3.99 for 2.3 lb. In many cases, the large unit tend to be cheaper than the small unit. But it's not always right as you know.
This tool shows you which one is cheaper without using calculator. Let's shop wise and save your money.
Since there is no keypad available with combination of numbers and dot in iPhone/iPod touch, I created the original keypad.
There is a preference setting view along with the main view. Tapping the information button, which is little circle "i" located on upper right corner on the main view, or just double tap on the main view except buttons and windows are located, the view flips to preference setting.
You can select from two keypads: telephone type which has 1, 2, 3 button from upper left, tenkey type which has 7, 8, 9.
You can also select from eight images for key button. The background and button title color can be set among full colors, and save them up to three sets. Therefore you may change the color of this tool whatever fits on your imagination.

Three parts of its color are selectable: BG(background), Button1, Button2. BG is the background color on main view. Button1 is the title color of numeric, dot and "delete" buttons. And Button2 is the title color of "All Clear", "Start", "Clear" buttons.
Changing the color, you may use the combination of slider of R(Red), G(Green), B(Blue) and A(Alpha), or if you tap on the numeric window you can change the value directly.
