Lots of potential, but deal breaker – Grafio Lite 3 - Diagrams & Ideas Review

First off, I appreciate the developer offering a free 'lite' version for me to evaluate. I've 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'.
