ES Calculator (Endo Scientific

Scientific calculator designed for everyday tasks of scientists and engineers

ES Calculator is developed for studying an ideal user interface (UI) of the scientific calculator. Its operation principle was based on the second generation (input as equation sequence) scientific calculators of Japanese manufacturers (CASIO, SHARP), and modified to further improve the usability. The user interface is elaborated as intuitive as possible, that enables users to get answers with a shortest key stroke sequences. Major physical constants are called by just two key strokes.

This app is made as a outcome of the project, whose ultimate goal is to develop an ideal scientific calculator and put into market. Your valuable feedback is very welcome.
