Two graphics editors, ported from PC. You will need mouse, stylus, or 10” screen to use them - stylus combined with 10.1” screen gives best results wink wink.
GIMP is an advanced picture editor suitable for such tasks as photo retouching, image composition and image authoring.
Inkscape is a vector graphics editor, which has everything needed to create professional-quality computer art.
They both support stylus pressure. In Inkscape, you will need to enable Generic pointer in File -> Input Devices (see screenshots).
For best results, also enable Windows -> Single Window Mode in GIMP.

I would appreciate if you make a video of using this app on a big tablet with stylus, to replace my poor video with 5” phone.
