Tracing Paper - Light Box for for Android

Quick summary

Tracing Paper – Light Box (created by Csákvári Dávid) is an Android utility that turns a smartphone into a makeshift lightbox so you can place paper over the screen and trace an image. It’s built for simple transfer and sketching tasks: load an image, arrange it on the display, and trace directly onto physical media. The app emphasizes straightforward tracing features rather than photo editing or complex drawing tools.

How it works

The app projects the chosen image full-screen on your phone so the device itself becomes the illumination source for tracing. After loading an image, you can position it and then put paper over the screen to copy the lines. A keep-screen-on option prevents the display from dimming while you work.

Controls and display options

• Zoom in/out to focus on fine details
• Flip the image horizontally for mirrored tracing
• Rotate the image to line it up correctly
• Resize the picture to match the paper or desired scale
• Change the screen brightness to improve contrast
• Pick a background or backdrop color to enhance visibility
• Enable a screen lock to stop accidental screen sleep or changes

Source code and community involvement

Tracing Paper – Light Box is open-source and hosted on GitHub. Because the repository is public, users can inspect the implementation, file bug reports, and suggest enhancements. This openness helps foster transparency and allows interested contributors to propose fixes or additional features.

Best fits and constraints

This app is ideal for casual tracing and quick sketch transfers when you need a simple, portable solution. It lacks advanced image-editing or vector tools, so it isn’t intended for detailed digital illustration work or professional-level editing workflows. Expect a compact feature set aimed at reliability and ease of use rather than extensive creative controls.

Alternative to try

Papercopy - Tracer Free is a commonly suggested substitute for those who want a different app with comparable tracing functionality.
