GTReasy+

The GTReasy + is a graphical calculator designed specifically for school use and all major tablets. All required functions are clearly sorted and understandable through the intuitive controls without a manual. Of course, the app also includes a test mode, which logs the activation of leaving the app and thus allows safe use in exam situations.
The functions plotter makes it easy to create, plot, analyze and display functions in function value tables. Derivatives at the location, the area under a curve and also the intersection between two functions can be displayed automatically.
The classic calculator range scores points with unique function names, helpful feedback and search functions as well as a comprehensive function catalog. Numerical solvers for displaying interfaces and real zeros as well as for solving systems of equations are of course available.
In addition to a clear overview of tables, the statistics section offers a choice of numerous diagram types and a clearly structured analysis section, which includes descriptive statistics, different regression approaches, and binomial and normal distributions.
Especially handy: three profiles allow you to store different settings and save, for example, to recall for different fan requirements.
