Comparison of Android drawing apps

Artecture

Pros:

-Amazing live paint mixing and realistic brushes

+Free version allows exporting to various formats including png

+Many brushes and brush options

+Good layer support

+No disturbing ads even in free version

Cons:

-No obvious way of changing the brightness of brush color (it’s easy to change the hue and saturation though). EDIT: you can change it from the paint bucket symbol at the top (confusing because a paint bucket symbol usually means a fill tool)

-Frequent crashes

-Limited size options for canvas

-No vectors

-No obvious way of transforming (rotating scaling etc) what you have drawn. You can accomplish it via copying and pasting a selection to another layer though.

-No numeric way of setting color values (makes copy pasting colors from other apps difficult.

Medibang Paint

Medibang Paint is not very well known in the segment of Android drawing apps, but it’s actually a very decent contender. I will need some more research before listing the pros and cons but one definite pro is that the app is free. It also seems to have free desktop versions for both Windows and Mac.
