 Q1. What’s difference between free version and paid one?


Answer:As of August 2016, a large difference of the Panecal (Ver.6.3.0) between the free version and the paid version is a advertising banner display and the expressions display area. The display is larger than free version, because the paid version isn’t displayed advertising banner. In addition, the paid version it is possible to easily change mode by tapping the status of the top of the screen. There is a difference in some of the menu item, but it is the same functions as a basic scientific calculator.
