The app helps you annotate over your screen and teach/present better in your online classes.

The motivation behind the app was generated because of the need of screen annotation in programming/development classes. Explaining code directly while annotating is a big plus point and helps in explaining the concepts better.

This is an open source project and you can also contribute to make this app even better.
