About

DoodLoop

Read full description

Draw it. Flip it. Loop it. DoodLoop is a frame-by-frame animation studio for iPad and iPhone, built for Apple Pencil and just as happy with a finger. Sketch a drawing, change it a little on the next frame, and watch your cartoon come to life on a loop. No ads, no watermarks, no subscription. Your cartoons, your files, yours. DRAW • Apple Pencil pressure and tilt, tuned for line work, on paper that behaves like paper. Drawing with a finger gets a stroke stabiliser, so a shaky line comes out smooth. • A full kit: brushes, eraser, fill, smudge and blur, shapes (line, rectangle, ellipse, triangle, star and more), text, and symmetry. • Layers with blend modes: sketch below, ink above, shade on top. ANIMATE • A timeline made for flipping, with duplicate, reorder, and holds. • Onion skinning ghosts the frame before and after, like tracing paper on a lightbox. • Set the frame rate, lift the pencil, and your animation plays while you keep tweaking. SOUND & SHARE • Record your voice or sound effects right in the app and line them up with your frames. • Export clean, full-resolution MP4 video, animated GIF, or a PNG image sequence. Never watermarked. OWN YOUR WORK • Every project is a real .doodloop file in the Files app: browse it, copy it, back it up anywhere. • One-tap backup and restore for your whole library. • Import your existing FlipaClip projects and keep animating. FREE TO START • Download DoodLoop free and start animating today. • One optional, one-time Pro unlock opens up higher frame rates, larger canvases, and pro export formats. No monthly fee, no rented features, ever. DoodLoop is made by Nubisco, Lda. Questions, bug reports, or ideas? A human who actually works on the app will answer.
