TraceOverlay vs TraceLock

Trace images onto paper with the camera you already carry. TraceOverlay places a reference over your live camera view, turning your iPhone or iPad into a practical tracing lightbox for drawing, painting, lettering, murals, and art study. TRY THE INCLUDED DEMO TraceOverlay includes a Mona Lisa tracing demo so you can use the live camera and every precision tool without an account or purchase. TRACE WITH PRECISION • Move, scale, and rotate the reference over your drawing surface • Adjust image and camera opacity independently • Lock the layout to prevent accidental movement • Use the alignment grid to check proportions • Mirror a reference when needed • Hide the controls for a clean tracing view FIND THE LINES THAT MATTER Use edge detection, grayscale, contrast, brightness, saturation, and invert controls to create a clearer guide. UPGRADE FOR YOUR OWN REFERENCES The optional one-time Unlock upgrade adds personal photo import and a private on-device reference shelf. It is not a subscription and does not renew. The App Store shows the localized price before purchase. PRIVATE BY DESIGN Camera frames and selected reference images are processed on your device and are not uploaded to TraceOverlay. No TraceOverlay account is required. MADE FOR CREATIVE WORK TraceOverlay is designed for artists, illustrators, lettering practitioners, muralists, art students, and hobbyists who want a portable tracing aid without extra projection hardware. Open the included demo, frame your paper, and start tracing.

Turn your iPhone or iPad into a tracing lightbox: import an image, position it, lock the screen against accidental touches, place paper on top, and trace. TraceLock is intentionally focused. It solves one specific job with no account, no ads, and no cloud photo uploads. • Import an image from Photos • Convert it to sketch, outline, comic, black-and-white, or high contrast • Scale, move, rotate, and mirror it to fit your paper • Lock the canvas so paper and palms do not move the image • Keep the display awake and use full brightness while tracing • Hold for two seconds to unlock safely Photo processing happens on your device. TraceLock does not collect personal data. Try every feature with total peace of mind.
