Fomcal is a calculator to calculate quickly with formula inputted already. Since you can register formulas used in daily routine by yourself, there is no need to search or to develop the dedicated calc app. Moreover, Fomcal can be also available as a general function calculator pad (option).

The result can be exported as CSV data. Following formulas are preset as samples. ・Hypotenuse of Right Triangle - Geometry ・Cross-sectional Performance of Rectangle - Mechanics of materials ・Roots of quadratic equation - Mathematics ・Compound interest calculation - Business ・Number of years to become N times with compound interest calculation After purchase of "Enhancements (former Restriction Release)" with In-App purchase, you will be able to following functions. ・Export/import of formula data. ・A special numeric pad will be utilized for efficient inputting. ・Function calculator pad. ・Parameter study. From Ver.3.3, "Extended Syntax" feature is available. With $IF, $FOR, $WHILE or etc., branch or iterative operation is easily specified.
