Drop ready-made components onto an infinite board, arrange them your way, and export crisp, print-ready PDFs. Every board lives in iCloud and follows you across Mac, iPad, and iPhone. KEY FEATURES • Infinite boards — one home for every idea: app flows, landing pages, moodboards, reports, and more, side by side on a single canvas. • 200+ ready-made components — mobile cells, cards, lists, tab bars, desktop windows and controls, web sections, and wireframe blocks. Drag, drop, done. • Every platform on one board — sketch a wireframe, refine the mobile screen, and design the matching website without switching tools. • Real typography — full font, weight, spacing, and color control for text that looks like the real thing, not a placeholder. • Smart guides & measurements — snapping, alignment guides, and pixel distances as you move things around. • Device frames — present your work in phone, tablet, laptop, desktop, and watch frames. • Apple Pencil drawing — sketch and annotate naturally, right next to your mockups. • Layers & precise control — select, lock, reorder, and fine-tune every element. • Crisp vector PDF export — even huge boards export clean, sharp, and print-ready. • iCloud sync — start on the Mac, tweak on the iPad, show it from your iPhone.
