Krita (formerly called KImageShop, Krayon) is a free, open-source and cross-platform digital painting software developed by Krita Foundation (part of the KDE Community) from Sweden. It is fully functional, capable of the entire painting process from drafting, lining, coloring to post-adjustment; can draw concept sketch, illustration, cartoon, animation, scene and 3D mapping; supports digital board, pressure sensing, anti-shake, layers, filters, color management, and other functions.

Adobe Fresco (formerly called Project Gemini) is a digital drawing and painting application developed for touch control devices, launched by Adobe Systems. It realizes the most "natural" brush strokes and the perfect mixing between different colors. Its main rival is the very distinctive drawing application - Apple Pencil that is what Apple was doing its best to promote, and has been a favorite productivity tool on iPad for many graphic artists and illustrators.
