Tracevelle: Tracing Lightbox

Your pattern. Perfectly still. Turn your iPhone or iPad into a focused tracing lightbox. Bring an embroidery reference, stencil, lettering study or craft pattern, prepare it on screen, then lock its position while you trace onto suitable thin paper. IMPORT YOUR OWN PATTERN Choose a JPEG, PNG or HEIC image from Photos or Files. Your original stays preserved, with all image processing on your device. PREPARE AND TRACE — INCLUDED FREE Move, resize, rotate or mirror your current pattern. Adjust contrast or try an outline view. Use a physical ruler to calibrate the screen setup and set the image width in centimeters or inches. Lock editing gestures, then hold the visible unlock control to return to editing. Optional brightness and stay-awake controls support a tracing session; system gestures remain available. The complete single-image workflow and current-work recovery are free, with no timer or watermark. SAVE TIME NEXT SESSION — LIFETIME PRO Build a named local pattern library. Find a saved pattern with search, duplicate a project for a variation and rename it for the next piece of handwork. Save reusable size, contrast and outline presets for another pattern. One purchase, no subscription. The upgrade is optional; existing saved work remains accessible. Library and Save Pattern are available directly in your workspace. No account, ads, AI service or cloud upload. Paper transparency and physical sizing depend on your device and setup. Recheck calibration with a ruler when the screen or window configuration changes. Image width includes any blank margins in the imported image. Saved patterns and settings remain on your device; this is not cloud sync.
