Lina Pad:PDF Notes & Recording

Your handwritten notes can remember more than words on a page. Lina Pad is a focused PDF note-taking and lecture recording app designed for iPad. Import class slides, handouts, research papers, or meeting documents and write directly over them with Apple Pencil. Prefer a clean page? Create a blank notebook and choose ruled, grid, dotted, or plain paper. As you write, Lina Pad keeps your vector handwriting and lecture audio on the same session timeline. When it is time to review, select handwriting from that session to return to the related point in the recording. Instead of scrubbing through a long audio file and guessing where a topic began, your own notes become a visual way back into the lecture.
