Rolled Paper Calculator has award for 2010 the best iPhone App in Japan (AppBank)

Ver4.0 become internal calculation to 128 bit hight accuracy, and add the triple-digits comma, using by PRO engine.

by jeffry1461 I feel shock ( ̄▽ ̄) - because this App is too much well made. The most brilliant point is this concept.

by jyaian I had just looking for this App!! It's nice to share the process of calculation with everyone around it. Simple and practical.

Roll Paper Calculator records all input and result history, then you can confirm there is mistake or not at the process of calculation. There is more functional PRO version, the paid App, but I release the Lite version (first version of paid App) as free App, for the people who think Lite version is good enough for usual day.

This App outputs the history of calculation on the paper(look like). And when it goes out of display, you can see it by dragging the paper using your finger.

Usage: the calculation in the shopping, lots of calculation like house hold budget, usual calculation because of its record on "The New Paper".

by rum(external site): The standard calculator is hard to use, then I had looking for some of good use. Then I just found it. It is very useful to remain all input. -> Thank you very much. I hope it will be helpful for long time.

by Chachao0 It is useful to see multiple line of input. How can I turn off the sound? -> You can turn off sound using the iPhone's mute button. There is up on the button of sound volume.

by niko It is very excellent App! I use it for the calculation of the monthly sum of household account. It is really useful to review the calculation result. Hopefully when I could correct the error result, this App become most strong calculator! This app is so far helpful for free, I recommend strongly to download it. -> It can not edit the history. But the PRO version has the re-enter function, then you can correct the result using this function and inverse operation.

Lite version is function limited version,then It cannot show comma-delimited. But devising the button aliment , the size of paper is same as PRO version. And you preliminarily should know the limited function that the paper become white when the App is end, it has no warp function for the paper movement (only dragging), it has no E-mail function, etc.

The PRO version , the paid App, accomplished 10,000 downloading. This app has revolutionary function that it make replacement traditional "M+" function to "The NEW PAPER". And it has warp function for fast movement on the paper, and it has function of persistent data when the App is end. And the newer version become again as "communication calculator" by E-mail function that send the calculation data regardless when and where you are. And in addition it has VAT(Value Added Tax)+/VAT- function, the numbers of decimal control. Try use it and I thank you and appreciate on your purchasing the paid App.

Cool calculator

I love this calculator. It's just like using a ten key calculator. Gave four stars because iPad app is slightly different from phone app. This one is very basic where phone app has separate buttons for %, VAT, cut 4/5, etc., but it does the job! Love it!

What's the deal?

I really want this to work, but AS SOON as the app is opened, it crashes.
