No, MathPad EDU is not free; it is a paid full version.
Specifically, MathPad EDU is offered as a complete software package that requires a purchase. Unlike applications that might offer a free base version with subsequent charges for additional features, MathPad EDU is designed to provide full access to all its functionalities upfront, with no in-app purchases required once acquired. This model ensures that users, particularly in educational settings, have a comprehensive tool without hidden costs or incremental upgrades.
