## Description

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.
