iPhone, iPhone Duo, and iPad

Every screen

Your library laid out for each screen and kept in step through your own iCloud. On iPhone Duo, folders show a list beside a preview, so you pick a file on one side and read it on the other.

Closed covers

Slide the band, hold, open

Every notebook opens on its cover, full screen: your own photo, a seasonal design, or one you make. Slide the elastic band to the lock and hold for three seconds, then turn the cover like paper.

Notes that open like a book

Notebooks

Lined, grid, Cornell, and to-do paper, with Apple Pencil on iPad and iPhone Duo and a finger on any iPhone. Type in a handwriting style that looks like your own notes. On iPhone Duo and iPad in landscape, two pages lie open across the fold, and ink thickens and tapers like a real nib.

iPad and iPhone Duo

Hold to snap

Draw a rough line, box, triangle, or circle and hold the Pencil still for a moment: it snaps clean. It works in notebooks and in Sketch Studio, and one Undo takes it back.

Your month, mapped out

Planners and journals

Hyperlinked planners with real dates, on iPad and iPhone Duo. Planners come with a tappable Contents page, a tap on a date opens that day, and every day page links back to its month. On iPhone Duo, a link opens its page on the facing side.

Organized and private

PDFs

Highlight, ink, sign with saved signatures, fill forms, and manage pages with merge, split, compress, and password tools, on every screen. Redact for real, with the hidden text destroyed rather than covered.

Every file, one library

Libreto Intelligence

Ask questions about any PDF or notebook and get answers with tappable page citations. Summarize a selection, turn a document into flashcards with spaced repetition, or record a lecture and have it transcribed and summarized on device.

Built for Apple Pencil

Drawing studio

A layered canvas with blend modes and per-layer opacity and 56 brushes across 8 categories, on iPad and iPhone Duo. In landscape, Sketch Studio docks your reference image, layers, and colors beside the canvas.

iPhone Duo

Unfold it

Folded, the cover screen shows the notebook you were writing in, band and all. Unfold it and the notebook opens right where you left off: two pages across the fold held sideways, one page held upright, with every control in one row at the top either way.
