A free app for Android, by Irma Studio.

Superhero Coloring is a coloring app that is the best way to spend time on your mobile device, either while waiting for someone or while relaxing. The game contains various images of superheroes that you can use to create a new and unique drawing.

It is an entertaining way to kill time, improve your creativity and imagination, and sharpen your art skills. 

This is a great way to develop your imagination and creativity. You can use your own pictures, or you can choose from the many available images. 

You can choose from a variety of colors, and you can use a variety of different tools to paint the images. You can use the pen to draw, the eraser to erase parts of the drawing, the paint bucket to paint the entire image, and the palette knife to spread the paint.
