UnivNote — Smooth PDF Note App UnivNote makes the fundamentals — writing, reading, and organizing on PDFs — fast and reliable, instead of leading with AI. Write on textbooks, slides, papers, and books with iPad and Apple Pencil — open your notes on iPhone and Mac. Recent updates added layers, shapes, memorization tests, exam countdowns, and study time tracking while improving speed, heat, and battery on stroke-heavy pages. ▶ What Makes UnivNote Different · A simple writing tool without AI clutter Responsive pen, fast lasso, easy copy and paste, and a stable PDF reader come first. · Layers — keep the original and your notes apart Keep handwriting, answers, and corrections on 5 layers per note. One tap hides or shows the answer layer everywhere; lock layers to protect originals, move lassoed ink between them. Unused, they tuck behind one button. · Study tools for memorization and review Cover answers with the masking highlighter, tap to reveal. Hide or show all masks, self-grade right/wrong tests, move down the mask list — flow never breaks. Each subject folder shows an exam countdown and logs study time. · Shapes you can re-edit anytime 30+ shapes — lines, arrows, polygons, cylinders, cones, spheres. Drag handles after inserting to tune an ellipse's flatness or a cylinder's shell thickness — great for math and science. · Fast writing with lower heat Input stays responsive as strokes pile up; eraser, paste, undo, and lasso stay smooth. Heat and battery keep improving under load — Split View, screen recording. · Built for lectures and class notes Laser pointer, reading mode, gesture shortcuts, recording, handwriting-synced playback. Recordings survive crashes and continue in the background. · Extend PDF margins on all four sides Add the mm you want per side for problem solving and notes. · Word-aware highlighting on PDF text Long-press and highlights snap to words; text stays black, never washed out. ▶ Main Features · Pen, highlighter, eraser, fountain pen — widths, colors, line styles · Layers — 5 per note, hide, lock, rename, move via lasso · Shape insertion — 30+ flat and 3D shapes, re-edit with handles · Masking highlighter — masks, right/wrong tests, mask list · Exam countdowns + auto study time per subject · Lasso selection — move, resize, rotate, copy, cut, duplicate, delete · Eraser capture delete — wipe all ink inside a closed area · Paste images — photos, screenshots, crop · Share sheet import — PDFs and photos from any app · Audio synced to handwriting — tap a stroke to jump there, up to 3x · Backlinks — all links pointing to this note · Text boxes with text style presets · Favorite pens + per-note tool memory · No-Pencil mode — finger writing, two-finger scroll · Page manager — add, delete, duplicate, rotate, multi-select · Sidebar table of contents — detects and edits PDF Outline · Unified search — PDF text, text boxes, note titles · Reading mode, laser pointer, gesture shortcuts · Design templates — study, planner, journal, creator · Folder library — nested folders, colors, favorites · iCloud sync — notes stay on device when off · WebDAV — import and full backup upload · 27 languages — 한국어/English/日本語/简体中文/繁體中文/Español/Deutsch/Français/Italiano/Português/Nederlands/Svenska/Dansk/Norsk/Suomi/Polski/Čeština/Magyar/Română/Ελληνικά/Русский/Українська/Türkçe/Tiếng Việt/ไทย/Bahasa Indonesia/Bahasa Melayu ▶ Pricing · Free for up to 20 notes · Unlimited Notes is a one-time lifetime purchase · No subscription · No ads · Family Sharing supported · Early Supporters automatically get Unlimited Notes ▶ Privacy · No note data is sent externally · Notes stay on your device or your own iCloud ▶ Recommended Setup · iPad + Apple Pencil recommended; iPhone and Mac supported · iPadOS 18 or later, optimized for 13" and 11" iPad Pro / iPad Air
