Krita

Krita is an excellent app for creating professional illustrations and digital designs on your Android tablet. With Krita, you can create gorgeous illustrations from scratch with either pixels and vectors, depending on what you like to work with.

Krita has countless tools and resources, which can make it a little overwhelming at first glance. That said, with proper training in digital illustration, you'll have no trouble making the most of all its features.

Krita also offers templates, which are useful ways to create designs within specific parameters. For example, if you want to draw a comic and print it out, the app will use a special color mode for printing. If you want to make illustrations to use online, on the other hand, the app will optimize the size and colors of your creation with this purpose in mind. Even better, Krita is an open-source software and a beloved tool among illustrators looking for free programs. The app also includes dozens of brushes, lets you work in layers, and gives you the option to edit preexisting images or create them from scratch.

Krita is an excellent digital illustration tool that holds its own with the best of them, even expensive programs like Adobe's.
