Libreto is a digital notebook, planner, PDF editor and full drawing studio for iPad and iPhone Duo, and a streamlined PDF editor and notes app for iPhone. A notebook that opens like one, private by design, with on-device AI included and one fair price. START WHERE YOU LEFT OFF Libreto opens on Start: your latest work up front, and a new Notepad, Planner or Sketchbook one tap away. Everything you make lives in one Library, sorted into notebooks, planners, sketches and PDFs. A NOTEBOOK THAT OPENS LIKE ONE 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 to open it, turn pages that curl like paper, and swipe a closed cover to reach the next notebook. MADE FOR IPHONE DUO Folded, the cover screen shows the notebook you were writing in, band and all. Unfold it and the notebook lies open across both pages, each one whole on the screen, right where you left off. Every control sits in one row at the top. NOTEBOOKS FOR APPLE PENCIL (iPad and iPhone Duo) Lined, dot grid, graph, Cornell and to-do paper, or a photo, in any paper colour. Ink thickens on slow strokes and tapers at the ends, like a real nib. Draw a rough line, box or circle and hold: it snaps clean. Underline, strike out or circle typed words and the mark stays with them. Type around photos, or lay out text frames with columns that run on from page to page. Search your handwriting and convert it to text on-device, in 20+ languages. Add stickers, washi tape, photos and AI art with Image Playground. No Pencil, or another iPhone? Write with a finger. PLANNERS, YOUR WAY (iPad and iPhone Duo) Daily, Weekly, Monthly and Pro planners, plus ready-made planners for school, work, fitness and money. Real dates, a tappable Contents page, and every day linked to its month. Light or Dark theme. DRAW & SKETCH (iPad and iPhone Duo) A full drawing studio: pressure brushes with textured tips, dual brushes, and brushes made from your own pictures. Layers, groups, Layer Sets, blend modes, layer masks and live adjustment layers you can change at any time. Vector shapes and text with gradients, tapered and dashed lines. Heal, clone, dodge, burn and liquify. Warp and rig your art, and draw on isometric planes. History with branches lets you step back to any point. Symmetry: vertical, horizontal, both axes or radial. Choose a Dark or Light look. Open and save PSD files, or export as PNG or PDF. PHOTO TOOLS IN SKETCH STUDIO (iPad and iPhone Duo) Develop RAW photos. Merge shots into panoramas, HDR images, or a crowd-free scene. Mask hair and fur with the Edge Mask Brush, and measure in real units. PDF TOOLS (iPad and iPhone) Highlights, ink, shapes, stickers and signatures, with undo and redo for every mark. Reorder, rotate, split and extract pages. On-device OCR and Scan Enhance for scans. Redact for real: the hidden text is destroyed, not just covered. Export as PDF, image, text, Word (RTF) or Markdown. LIBRETO INTELLIGENCE, ON YOUR DEVICE Ask questions about any PDF or notebook and get answers with tappable page citations. Summarize a document, a page range or a selection. Turn any document into flashcards and quizzes with spaced-repetition review. Record a lecture, then transcribe and summarize it on-device. All of it runs with Apple Intelligence, right on your device: nothing uploaded, nothing metered, no AI credits. Prefer no AI? One switch hides every AI button. PRIVATE BY DESIGN No ads. No tracking. No third-party AI. Your work stays on your devices, with optional private iCloud sync and App Lock with Face ID. MEMBERSHIP Unlock every premium feature for $19.99/year with a 3-day free trial, or $2.99/month. Prefer not to subscribe?
