Educational apps for iOS and Android

App for practice on exponential equations.The App offers exponential equations who ALWAYS CHANGE and provides the COMPLETE SOLUTION !!!!An ideal tool for the study of mathematics in high schools and technical schools.Also suitable for teachers who need to create exponential equations as a task for students.

App to learn LOGARITHMS.The app creates equations and expressions and SHOWS THE COMPLETE SOLUTION !!!An ideal tool for the study of mathematics in secondary schools and technical schools.It is also possible to learn the logarithm laws (simplify and expand expressions). Fundamental to be able to solve the equations.Includes a calculator for the calculation of logarithms to any base.Works 100% offline.Also suitable for teachers who need to build logarithmic equations as a task for students.

Learn all about the roots!!!This app generates equations and exercises who are ALWAYS DIFFERENT and provide the COMPLETE SOLUTION !!!!The ideal tool to prepare an exam in algebra or mathematics.Also very useful for teachers who have to prepare the homework or examinations for their students.With this app you can learn and practice ALL TECHNIQUES involving square roots and roots of a higher order.

Solver for quadratic equations (ax^2+bx+c=0) and biquadratic equations (ax^4+bx^2+c=0).The app can calculate real and complex solutions.It is also possible to plot the functions and to zoom in and out.You can input decimal coefficients (e.g a = 1.5) or fractions (e.g a = -4/3).This solver is useful for mathematics, physics and algebra calculus.

Percentage calculator, very easy to use.The app can solve every problem about percentages and also shows the calculation made to find the solution!

App created to practice on MATHEMATICAL EXPRESSIONS. The ideal tool for anyone who needs to learn the expressions. The App creates always different calculations !!! Also great for teachers who must prepare the tasks for their students.Try to solve the exercises with pen and paper, if you don't know how to do it,the app will show you COMPLETE SOLUTION!

System of linear equations.The App also GENERATES 2x2, 3x3 and 4x4 random systems and shows the solution !!! The ideal tool for students who must exercise systems of equations and also for teachers who need to "invent" exercises for students.

Calculator for Scalar product (dot product),Cross product, Scalar triple product (Mixed product) and Angle Calculation. Very easy to use.

"CalcTutor" is the new app to practice addition, subtraction and multiplication. It is possible to set up three difficulty levels: "Easy", "Medium" and "Difficult". To be successful in mathematics it is very important to have undergone the ownership of the basic operations. Without the necessary preparation it is practically impossible to proceed in the study with themes like fractions and equations.

Financial mathematics calculator, very easy to use. The App can solve equations. In the screenshots the user input is black, the calculated data are red. FinCalcPro CAN SOLVE EVERY VARIABLE OF THE ABOVE LIST!

Finance mathematics calculator for percent calculation, linear interest, compound interest calculation, unteryears of age interest, steady interest, pension calculation, everlasting pensions, linear write-offs, degressive write-offs. . . . a very easy service.

After graduating in mathematics at the University of Zurich have taught in various schools and worked as a software engineer.

Combining these knowledges I dedicate myself now to the App development focused on the educational field.

I also provide consulting for clients who want to realize their own ideas for new Apps on iOS and Android platforms.
