Prop your phone above a sheet of paper and the drawing appears on it. Follow the lines with your pencil, and a portrait, a lettering piece or an Ottoman ornament takes shape under your hand. Trace on paper Pick a template or a photo and see it over your paper through the camera. Set the line opacity, move, scale, rotate or mirror it, then lock the screen so a stray touch never shifts the drawing. Hold the lock badge to unlock. Handheld with AR On iPhone and iPad, AR pins the drawing to the paper's surface, so it stays in place even when you hold the phone in your hand. Light box Lay thin paper on the screen and trace the glowing lines. Brightness goes up while the light box is on, and the camera is not needed. Your photos as sketches Turn any photo into clean line art on your device: Outline, Detailed, Shading or Grid, with adjustable detail and line weight. Remove the background to keep only the subject. Templates from pattern books Nearly a thousand line drawings traced from public-domain ornament books: tezhip and rumi scrolls, Islamic star and girih geometry, moresque and Cairo plates, borders, rosettes, Celtic knots, Gothic tracery, Renaissance and Baroque ornament, Byzantine and East Asian motifs. Each one shows its difficulty and roughly how long it takes. Step by step Step mode splits a drawing into stages, so you trace the big shapes first and the details last. Lettering Type a word, choose a typeface, bend it along a curve and trace it for a poster, a card or a cake. Timelapse Record your session and get a short video of the drawing coming together, cropped to the paper, with a before and after reveal at the end. Also in Traceline • Projects keep your finished pieces with a photo and the timelapse • Share an image from Photos or Safari straight into Traceline (iPhone and iPad) • Template of the day widget, a Live Activity timer and a Control Center button • Works on iPhone, iPad and Mac, in light and dark mode Traceline needs no account.
