I use Mypaint since many years, for graphic palets worskhops with children , and I have just positive feelings about it. Many tools, rather easy to use, and great compatibility with my Wacom. Recommanded.
Essentially, I've found the more time you have to spend spend learning the apps and/or using its tools, the less time you have to actually enjoy the art of creating. Try apps that cut down the friction between you and your art; Krita, MyPaint, etc. Would be my first suggestions since they're free, then maybe ArtRage, or Sketchbook Pro if money is not a concern. - Source: Reddit / about 23 hours ago
Note: The .gpl format is also supported by Aseprite, Drawpile, Krita and MyPaint. - Source: dev.to / 18 days ago
Mypaint (http://mypaint.org/) is simpler to use than Krita. Krita can be 'simplified' a bit by closing some of the unnecessary docked tools on the right. - Source: Reddit / 3 months ago
Take a look at MyPaint or look here to see if something tickles your fancy. - Source: Reddit / 10 months ago
Checkout MyPaint for illustration. Coloring at least. It's free. http://mypaint.org/. - Source: Reddit / over 1 year ago
