Lots of potential, but deal breaker

First off, I appreciate the developer offering a free lite version for me to evaluate. Ive added a star for that reason alone.

Unfortunately, during my evaluation, I came to realize the shape recognition is flawed (at least on my iPad Pro). Specifically, after trying to draw a square about 20 times, only two of them were actual squares. Every other time they were irregular trapezoids or similar. To use this professionally I need to be able to quickly create perfect squares, not almost squares.
