The best app I have – Grafio 4 - Diagram Maker Review

This is the best app that I have in my large collection of apps.I know that this is an app that is used for graphs and flow charts but I have found a different uses for it and feel completely satisfied. I wish I could draw without snap recognition and have it the color fill in. Could you ask explain the grids spacing and the angle step? Thank you
