Roll Paper Calculator Ver2.5 (to be update)

Roll Paper Calculator to be update next week , ver2.5.

Ver2.5 has functionality for time code recording,  data recording for perpetuation.

And so, more useful interface of arrow button, it will have up mode and down mode.
when it is up mode,  it moves top of data in long touch, and it is down mode, it moves bottom of paper in long touch.

I planed this function for Ver3.0, but  for  customer satisfaction, I think I must provide this function more quickly.

And if you are not Roll Paper Calc. user, when you would try it, you would have future calculator and will have experience of another world!!
