Calligraphy brush: Traditionally, these brushes were used for writing Chinese or Japanese letters, but now many modern artists use calligraphy brushes. They make thin, accurate strokes. You can change the stroke’s thickness using the slider.

Pencil: Use this to write or color like a real pencil. You can adjust the pencil’s thickness, but the strokes will always be very thin and grainy like an actual pencil.

Tilt pencil: This tool is used to mimic a tilted pencil. With this tool, you can get wider strokes than with the traditional point of a pencil.

Crayon: This is the third instrument from the right. It will give you the appearance and texture of a real crayon. You can adjust the width of the crayon’s stroke with the slider.

Fountain pen: It resembles a traditional fountain pen with its metal nib. Use it to glide across your screen when writing or drawing. You can adjust the pen's size with the slider.

Calligraphy pen: Similar to the Calligraphy brush, but in a pen version. It will mimic the strokes of a pen that has been dipped in ink. Use the slider to adjust the pen's size.

Eraser: This is located at the bottom of the screen. Use it to get rid of any mistakes or blemishes. Tap the Eraser icon twice to change its settings. Drag the sliders to adjust the eraser’s size and opacity. You can also tap Erase all to make the picture go back to its original state.
