This is a simple app that allows you to easily edit PDF files using your phone's camera. It has an interactive interface and an easy-to-use editing toolkit. With it, you can easily change the font, size, alignment, and margin of your PDF document.

You can also highlight, underline, and strike out text, add arrows, circles, lines, and more, and see all annotations at a glance. You can also rotate and resize pages and merge and split PDFs.

It can also save your changes to the original PDF file, so you can edit multiple pages in the same document at once.
