MoneySaver - Shopping calculator app for iPhone and iPad

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. Its 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 its not always right as you know.

This tool shows you which one is cheaper without using calculator. Lets 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.
