Scratch turns your iPad and Apple Pencil into the fastest notebook you own. Open the app, put Pencil to page, and start writing. No menus, no setup, no friction. HANDWRITTEN NOTES • Buttery-smooth Apple Pencil inking built on Apple's native PencilKit, for the low-latency feel you expect from paper. • Clean, distraction-free A4 dotted pages that scroll vertically and add themselves as you go, so there's always fresh space ahead. • A premium set of tools that stay out of your way: pen, highlighter, eraser, lasso select, custom colors, and adjustable widths. • Pencil writes, finger scrolls and zooms, exactly the way it should work. PDF MARKUP • Import any PDF from Files and annotate right on top with your Pencil. • Select text and highlight it in five colors, Google-Books style. • Your original PDF is always preserved. Annotations live on their own layer. STAY ORGANIZED • A clean sidebar library of folders that hold both notes and PDFs together. • Rename, move, and organize with a tap. • A thumbnail grid so you can see everything at a glance. BUILD THE HABIT • A Home dashboard with your writing streak, an orange contribution grid, and quick stats. • Jump straight back into your recent work. YOURS, EVERYWHERE • Sign in with Apple or Google and your notes and PDFs sync securely to the cloud. • Pick up on your iPhone with the Scratch companion to read and review on the go. • Full control of your data. Delete any note, or your entire account, right from the app. CONNECTORS, COMING SOON • We're building connectors so Scratch plugs into the tools you already use. Handwrite and mark up today, connect your workflow soon. Beautiful dark interface. Built entirely with native Apple frameworks for speed and smoothness. No clutter, no distractions. Just you and the page.
