NUMBER
by Keitaro Yamazaki


Of all the iPhone applications, “NUMBER” is the easiest calculator app to use.

The design is simple, but the innovation is the Ease of use.

The calculator is easy-to-use because of the incorporation of modern concepts of Cognitive Science.

- Even the size of the human finger was considered in the creation of the touch screen function.

- Swipe input correspondence:
  Swiping one finger upwards results in addition; swiping two fingers results in multiplication.
  Swiping the finger downwards results in subtraction; swiping two fingers results in division.
The “swiping” concept was designed for ease and natural use.


Review this app, and we will include the following additional functions:

- Changeable keyboard color
- Additional memory
