4 stars: This app is awesome except for 1 thing. It completely starts to freeze, lag, and crash on my samsung tablet. It's not like it's new, and I'm not too sure if the problem is my device, or the app. Also, I'd really like unlimited layers. Finally, please add finger gestures for example: two finger tap to undo. That would greatly improve the experience.
3 stars: Could be better for a quick sketch program. Can't really find myself using it as much as I would use Onenote to be fairly honest. I'd give this a 4 star for what it sets out to accomplish, but settled with a 3, do to my Note 9 pen being spotty at time(stock pen that comes with). If it's the pen, and not the program, let me know. However, the pen works in Samsung Notes and OneNote.
5 stars: Great for Huion drawing tablets, the only app for Android I found that responds to pressure and speed of the pen properly. It's honestly my go-to when using mine. For a phone screen and stylus, though, it's all up to preference. It's minimal and without distractions so it appeals to me pretty well.
5 stars: Its an amazing app. The tools are very nice and the sizes of the paper is grand and it helps me work on things better. It flows out very nicely and that is what i like about most apps is the flow. I can even probably start making manga scripts on this app :) the only difference is that i cant rotate my project and rotating usually helps when it comes to this kind of stuff but either way this app is pretty amazing ...
