This looks great and will come in very useful when presenting visual concepts (keep the audience focused).

One suggestion for future improvement would be auto shape snapping. I assume most will use this with a mouse which can result in squiggly, unsightly lines. A number of iOS note taking apps detect a similar shape and snap to straight lines or perfect circles. Hope that helps and thanks for the app.

Thanks for your valuable points. I am currently developing these features and would likely come in the next update. You could easily draw straight lines, arrows, circles, and rectangles.
