Finger Drawing Sketchbook App

Open your eyes in the morning and organize pictures of new thought patterns in your head.
mind with light sketches away from heavy notes and busy routines.
You can draw characters and texts with paper that matches screen size.
You can copy, delete, scale, and edit the picture by using the Lasso-tool,
and remove the unnecessary parts by the eraser.
It's easy to get started with a drawing app for mind mapping.
and complete my own sketchbook with stacked papers.

thanks and appreciate your encouragement with good comments.
