AnDraw

AnDraw shows an image full screen and switches off touch, so you can put a sheet

of paper on the screen and trace the image without your palm scrolling, zooming

or opening something else.

Adjust mode lets you place the image: pinch to zoom, drag to move, and buttons to

rotate and mirror. Press Lock to enter tracing mode, where every touch is

swallowed, the screen is kept awake, and brightness goes to maximum so the image

shines through the paper.

Any volume key switches between the two modes, and the volume itself never

changes.

AnDraw requests no permissions at all. Images are opened through the system file

picker, which gives the app access to the single file you choose and nothing

else.
