Two independent 2-line calculators in one single screen with unique % calculation, and international support!

Some people have just too many thinkings going on, and need more than one single calculator.

FEATURES:

- Easy per cent 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 your wish is answered.

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

- 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.

- 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!

- Easy copy & paste : A simple tap on the result from one screen, will immediately copy & paste the number to the calculator on the other screen.

A GREAT ADDITION TO OWNERS OF:
Check Please, Tip Calculator, Tipulator, TipStar, Percent Calculator, Good Calc, Tip Calc, HiClac, Sale Price, and such.

Pros and cons of Dual Calculator app for iPhone and iPad

Dual Calculator app good for

Yes, Im one of those who cant live without a calculator for 1+2=. I like how this one displays the whole formula and splits the screen into two. It can get pretty handy. ;-)
Its awesome! I use it for playing yugioh but somehow I think it reduces my battery.
Very handy calculator. Just wish it would save calculations if you need to exit app.
This app is great! I love it! I recently updated to iOS 8 though and now it does not load correctly, the calculator is cut off and you cannot use it! Please update for iOS 8!!!
I love this but right now it is not working with iOS 8. I hope you can send update soon. Thanks!

Some bad moments

Very basic and doesnt keep data on close. One dollar for an app Ill never use. Awesome.
developer communicates as if he takes feedback seriously but ends up doing nothing.
