DragNMath brings a new way to create and evaluate math formulas based on the visual programming concept.
It comes with an extensive set of built in functions and constants (including the Error function and the Gamma function).
DragNMath allows you can make your own formulas library that are specific to your domain of activity (Accounting, Engineering, Finance...)
Its uncluttered user interface provides very rich and powerful functionalities, most of them available with a simple drag and drop. The undo/redo operations are unlimited (up to the system resources) NOTE: DragNMath can only be purchased via the Mac App Store (the buy link redirects you to its App Store page). To purchase/download applications via the App Store an Apple account is required.
