## What is UnivNote?

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, and keep working on the same notes on iPhone and Mac. Memorize with the masking highlighter, review on schedule, and collect missed problems in Mistake Notes — your whole study flow in one app.


▶ What Makes UnivNote Different

· Fast writing with lower heat
Pen, eraser, lasso, and paste never stall, even as your notes pile up. We keep improving scrolling and note opening on stroke-heavy pages, along with heat and battery.

· Cover, test, and review on schedule
Cover answers with the masking highlighter and tap to check. Drag a rectangular mask with your finger to move it, or drag a corner to resize it. Right/wrong memory test results set your next review date, and the “Review” tab and Home Screen widget show today’s reviews and your weekly and monthly schedule. You can also set your own review intervals.

· Layers — keep the original and your notes apart
Keep handwriting, answers, and corrections on 5 layers per note and hide them with one tap. Edits touch only the current layer, so ink on the others stays as it is.

· Views built for workbooks
Choose Vertical scroll, Horizontal page turn, Horizontal scroll, or Two-page view, and keep your place with Lock Zoom and Lock View. Extend page margins on all four sides to make room for working out problems.

· Shapes you can re-edit anytime
30+ shapes, from lines and arrows to 3D shapes like cylinders, cones, and spheres. Keep fine-tuning their form with handles after inserting.

· Lecture recording and class notes
Audio recording with handwriting-synced playback, laser pointer, reading mode, and gesture shortcuts. Recordings are kept even if the app quits unexpectedly.

## Version history (last 5 releases)

### 1.114 — 2026-10-24

- Fixed iCloud Sync failing to turn on on iPhone and iPad with “Some changes couldn’t be saved.”
- When iCloud Sync can’t be turned on, Report a Problem now includes where it stopped, so the cause can be found and fixed faster.

### 1.113 — 2026-10-23

- UnivNote now draws PDF pages itself, so textbooks with many pages use less memory and show fewer blank white pages when you flip through quickly.
- Fill in PDF form text fields, checkboxes, pop-up menus and radio buttons with a finger tap. What you enter is saved in the note.
- With the text tool, a finger tap now creates or selects a text box. Dragging still moves the page as before.
- Fixed text boxes still showing through a mask placed over them.
- Fixed only the first photo being pasted when you copied several. They’re now all pasted in a grid, and one undo removes them all.
- An image you copy from another app is selected as soon as you paste it, so you can move or resize it right away.
- If an image on the clipboard can’t be read, you’re now told instead of nothing happening.
- Fixed lasso selections pasted as an image or added to Mistake Notes being saved blurrier than they look on screen.
- Reduced brief freezes when pasting a large image or copying a selection.

### 1.112 — 2026-10-22

- New notes and added pages now start as blank pages. Choose lined, grid, dots, graph, isometric or staff patterns and their spacing anytime from “Background” in the ⋯ menu. This works in Infinite Notes too.
- Background patterns appear only on blank pages, never over templates or imported PDF pages. Line spacing continues across pages, and patterns are included in exports, thumbnails and lasso copies.
- Touch the Apple Pencil to a page while it’s still scrolling from a finger swipe to stop it right there.
- You can now place the drawing toolbar vertically on the left or right side of the screen (⋯ › View Settings). Undo moves with it.
- “Button Visibility” and “Recordings” now open right inside the ⋯ menu instead of in a sheet that slides up from the bottom.
- When a search in a note finds nothing and the note has scanned pages that haven’t been recognized yet, you’re now pointed to “Text Recognition (OCR)”.
- When you use the same note on two devices, writing from the other device appears right away, and if both edit the same page at almost the same time, the changes are merged instead of the note being duplicated.
- If two devices added or deleted pages at almost the same time and pages went missing on one of them, those pages are now kept in a “(conflict copy)” note.
- Deleting, adding or moving earlier pages from the sidebar now keeps the page you’re reading on screen, and the note reopens at the page you were viewing.
- Fixed writing on some pages possibly disappearing when autosave ran while you were adding or deleting pages.
- Fixed all PDF links pointing to the first page after the note was saved again, for example after adjusting margins.
- Fixed the notice about edits saved on this device appearing again every time you opened a note after changing its pages.

### 1.111 — 2026-10-21

- Notes viewed with “Horizontal page turn” now open with the whole page (both pages in Two-page view) fitted to the screen. Fixed them opening at 100% with the right side running off the screen.
- The page no longer hides under the top bar or gets pushed off the screen when you first open a note, change the view mode or rotate your device.
- Notes opened in “Horizontal scroll” now put the page you chose in the middle of the screen, and the page number no longer changes when you nudge the view up or down.
- Fixed the saved zoom level changing to 100% when you closed a note right after opening it.
- The sidebar scrolls more smoothly in notes with many pages and no longer jumps back to an earlier page after you scroll.
- The sidebar’s Bookmarked Pages list now opens at the page you’re viewing, and you can add or remove a bookmark for the current page from the bottom of the All Pages list too.
- Fixed dark dots at the start and end of pencil strokes, and the darkness and paper texture changing the moment you lift the pen.
- Text boxes now shrink in height to fit their text, and a width you set with the handles no longer widens again as you keep typing.
- Fixed other photos on a page not showing while one photo on that page was still downloading or couldn’t be found.
- Further reduced cases where the eraser didn’t stop if you lifted your resting finger first, or pen input stopped after you switched to another app and back.

### 1.110 — 2026-10-20

- Following reports that finger scrolling or pen input stopped responding after switching to another app and back, the app now recovers stuck input on its own in more cases. If it happens again, please let us know with “Report a Problem” in the note’s ⋯ menu.
- Fixed an issue where syncing while you erased or moved a selection could create an unnecessary “conflict copy” of the note even though no edits overlapped.
- Fixed an issue where your palm or another finger touching the screen while you write could make the stroke in progress disappear, or keep anything from drawing until you lifted the pen.
- Reduced a case where handwriting near the edges briefly looked blank when you quickly zoomed out from a high zoom level.
- On iPhone, the vertical scroll bar on the right of a note is now hidden so it no longer covers the content.
- The keyboard shortcuts list (⌘?) now includes Search (⌘F) and ← and → for “Horizontal page turn,” and drops Apple Pencil hints that no longer matched once you changed your Pencil settings.
- Logs attached to “Report a Problem” now include more of what we need to find the cause, and no longer include note titles, file names or folder paths.
