Store listing

Description by Porcellus, Inc. Written by the developer, not by AppBrain. Click to read.
Compbook is a notebook app built for Apple Pencil, but compatible with third party styluses as well. No clutter — just open it up and start writing.

-Paper styles for every use
Choose from blank, college ruled, graph paper, dotted, and music sheet layouts. Adjust line spacing and colors to match how you like to work. Save your favorite setups as custom presets.

-More than just ink
Drop photos onto any page and arrange them alongside your notes. Record audio clips right on the page — perfect for lectures, meetings, or voice memos. Import PDFs and annotate them with your own handwriting.

-Find anything you wrote
Compbook recognizes your handwriting and lets you search across every notebook at once. Just type a word and jump straight to the page.

-Organize your way
Create as many notebooks as you need. Add, reorder, and remove pages freely. Each notebook gets its own cover — pick from classic composition, leather, denim, tie-dye, and more.

-Always backed up
Your notebooks sync automatically across your iPads with iCloud. Export everything as a single backup file to keep a local copy, or share it with a friend. Import backups to pick up right where you left off.

-Share your work
Export any page or an entire notebook as a PDF. Send notes to classmates, share sketches with collaborators, or just save a copy to Files.

-No nonsense
No login required. No ads. Your notebooks are yours. Get started free, or unlock Compbook Pro for unlimited notebooks, pages, and premium covers.
