About

I build UnivNote, a PDF note-taking app for iPad, iPhone, and Mac. I care about responsive handwriting, clear Apple-focused design, and making studying and review take fewer steps. I'd love feedback from people who work with textbooks and lecture PDFs.

UnivNote - Study PDFs with handwriting, layers, and synced audio

When a textbook's printed page 1 is PDF page 7, renumber it to match. Then annotate with Apple Pencil, extend margins for calculations, hide solutions on layers, test yourself with answer masks, and tap ink to revisit synced lecture audio. UnivNote brings these tools together on iPad, iPhone, and Mac with an Apple-focused design and no AI features. Try 20 notes free; Unlimited Notes is $9.99 once in the US.
