A real notebook, on your iPad. Write with Apple Pencil on pages that feel like paper, with a pencil that leaves real graphite grain and a pen that follows your hand. Perenne Note is made for people who think better with a pen in hand. No infinite canvas, no AI, no features you'll never use: just notebooks, planners and your ideas. Plus a free iPhone app to keep them with you. WRITES LIKE PAPER Pen, fountain pen, pencil and highlighter, powered by Perenne Engine, the drawing engine we built from scratch: real scanned graphite, paper grain that responds to every stroke, tilt and pressure in every line. Any width, opacity and color, eyedropper included. Turn on real notebook mode to flip pages with your finger and write with your Pencil, without switching modes. NOTEBOOKS THAT FEEL REAL 3D covers in 10 colors, 5 textures or your own photo. Blank, ruled, grid or dotted paper, or design your own with the pattern editor. Up to 100 pages, two-page spreads in landscape, colored bookmarks and over 280 stickers: stamps, postmarks and decorations. DATED PLANNERS Daily or weekly, in six styles you can switch anytime without losing a line of what you wrote. Tap a day to open it, tap the date to see the month. If you like, your Calendar events and your Reminders to-dos appear right on the pages, ready to check off with your finger or a mark of your Pencil. Your first planner is free to try. AUDIO NOTES Record a lecture or a meeting right on the page, even with the screen locked. Where your language supports it, transcription happens on your device: your voice goes nowhere else. ON YOUR IPHONE, FREE Your notebooks and planners in your pocket: flip through your pages as you wrote them, search everything and catch ideas on the go with quick notes. Text, checklists, tables, photos and audio, ready to place on the page back on your iPad. REMINDERS THAT TAKE YOU BACK Circle anything with the lasso and set a reminder: the notification arrives with your handwriting and takes you right back to that page. One-time or repeating, in your Calendar too. THE DESK Around your notebook there's room for sticky notes, photos and text you want to keep in sight while you write. Write on the notes, draw on the photos, move, rotate and resize everything. PRIVATE, NO ACCOUNT No sign-up and no ads. Your notebooks and notes stay yours and sync between iPad and iPhone through your own iCloud. Export pages or whole notebooks as PDF or PNG anytime. MADE TO FIT YOU Toolbar at the top or bottom, controls on the side of your writing hand, gestures to undo, keyboard shortcuts. In 14 languages, ready for iOS 27 and iPadOS 27.
