PCM Notes began with a very unglamorous problem: useful handwritten Physics, Chemistry and Mathematics notes existed, but revising from thousands of loose image pages was slow.
Turning an archive into a reader
The finished archive contains 91 chapters and 2,173 pages: 23 Physics chapters, 37 Chemistry chapters and 31 Mathematics chapters. Physics and Chemistry support JEE and NEET revision, while Mathematics is organised for JEE Main and Advanced.
During the Xcode build, an AppKit and PDFKit tool converts the tracked page images into complete chapter PDFs. Those PDFs are bundled with the iOS app, so the reader never needs to fetch study content from a server.
Why fully offline mattered
A revision tool should still work on a train, in a library with unreliable Wi-Fi or while deliberately keeping distractions off. Once PCM Notes is installed, chapter search, reading, zoom, page navigation, sharing and saved progress all work locally.
The app remembers the last-read page for each chapter. On iPad, the same archive can be viewed continuously or as a book-like two-page spread.
A deliberately simple product model
There is no account, advertising, subscription or paywall. Every chapter and reader feature is available immediately. The Support tab contains optional repeatable Apple tips, but a tip unlocks nothing.

If you revise from handwritten material, I would be interested to know whether you prefer long continuous PDFs or shorter topic-based sections.
