UnivNote — Smooth PDF Note App
UnivNote focuses on the essentials of reading, writing, and organizing PDFs instead of adding AI clutter.
Write directly on textbooks, lecture slides, papers, and books with iPad and Apple Pencil. You can also open and manage your notes on iPhone and Mac. Pen, highlighter, lasso, page management, recording, and search are designed to feel light and immediate.
UnivNote is continuously optimized for screen recording, Split View, Stage Manager, and multi-window use. Smooth handwriting, low heat, and long battery life are core priorities.
▶ What Makes UnivNote Different
· A focused writing tool without AI clutter
While many note apps emphasize AI summaries, automatic organization, and automatic search, UnivNote focuses on the handwriting experience itself. Responsive pen input, fast lasso editing, simple copy and paste, and a stable PDF reader come first.
· Fast writing with lower heat
Input stays responsive even when a page contains many strokes. UnivNote is continuously tuned to reduce heat and battery drain in heavier workflows such as Split View, multiple UnivNote windows, and writing while recording the screen.
· Built for lectures and screen recording
Use the laser pointer, reading mode, gesture shortcuts, audio recording, and synced playback. Whether you are taking class notes or recording an iPad lecture video, UnivNote helps keep controls out of the way and interactions quick.
· Lasso selection with instant actions
Select handwriting with the lasso and Copy, Cut, Duplicate, and Delete actions appear immediately. No long-press menu required.
· Extend PDF margins on all four sides
When a textbook or worksheet has too little margin, extend the top, bottom, left, or right side and write freely in the added space.
· Audio recording synced with handwriting
Record lectures or meetings while writing. Later, tap a note to jump back to that moment in the audio.
· Word-aware highlighting on PDF text
Long-press PDF text with the highlighter and highlights align to words precisely. Regular highlighter, masking highlighter, and opacity control help with review and memorization.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
This update improves the iPad experience for users without Apple Pencil and refines the reader menu.
Changes
- Added a mode for using pen, eraser, and pointer tools with your finger on iPad when Apple Pencil is not available.
- In this mode, one finger uses the current tool while two fingers are handled more reliably for scrolling and zooming.
- Improved the reader More menu so multiple settings can be changed in a row without the menu closing each time.
- Reading Mode is now a toggle inside the More menu, and its controls stay visible while the menu is open.
- The text input tool now enters text mode on the first tap, then opens saved text styles when tapped again.
- Import Photo now closes the More menu first and then opens the photo picker more reliably.
