4 stars: No matter how problematic it can be, it's undoubtedly the best Android drawing app on its optimal condition. It's almost 1:1 to the desktop version (which is super powerful), it's not just some cheap implementation as you can see a lot of planning for mini form-factor, and the integration is nice. Strangely, despite all the features, it has better S-pen latency compared to competitors.
4 stars: This app provides a lot of the best tools for art and animation projects, but I wish there was a symmetry tool on the canvas and a grid projeted on the canvas. There probably is, but I don't know how. Either way, great app.
