The main purpose of this paper is to contribute with some arguments in favor of the widest possible involvement of smart phones in education. The level of development of "smartphones", being in a substantial climb, offers enormous potential for raising the level of application development and use in all areas, including education. By presenting a concrete application made for such devices, we try to demonstrate the enormous efficiency of their utility and their productivity for both the teachers and the students in the study classes as well as the individual study. Such applications are particularly useful in the field of accurate science, especially in mathematics.
