This is a simple calculator for basic addition, subtraction, multiplication, and division for everyday use.

You may be wondering... "Why do I need to buy a calculator when there is already a built-in calculator from my iPhone/iPod touch?"

Hmm.. thats a good question.
Heres why you would want this lovely calculator.

- Unique % calculation : Okay. How much does it cost when the item on sale has an original price tag of $89.95 but marked down for 20% sale and an additional 15% down? You simply enter 89.95-20%-15%=, and voila, youve got the answer. Oh, the sales tax? Dont worry. Just press +8.95%= (or whatever your local sales tax percentage is) and you have the answer on your palm.

- BODMAS calculation : While this is not a complex RPN calculator, it follows the rule of scientific calculators and calculates divisions and multiplifications first. 1+2x3 is interpreted NOT as (1+2)x3 which gives the answer 9, but as 1+(2x3) which gives the answer 7.

- See your formula : 2-line calculator makes it easy to see what you have entered. Its less likely to make mistakes.

- Hear the voice : Whether you need it for practical use or just for fun, all buttons can be clearly pronounced. Just choose your favorite among Human, Robot, & Instrument.

- Beautiful skins : Wrap your calculator with vivid images that suites you the best.

- International Supports : Does your country express 123,456.78 as 123.456,78? How about separating numbers at every ten thousands, not at every thousands, like 124567 instead of 123,456? You can do it all!

- Big buttons : Last, but not least, big buttons! Its hard to make mistakes entering numbers when the buttons are this big. To make the buttons as big as possible, certain functions found in other calculators have been omiited. There are no square root, square, m+, m-, mc buttons, but who uses them anyway?

There is one hidden function, though.
A long touch of - button will act as a sign change function. :)
