Red SheetStep by step
-
Import the PDF. Tap + and choose PDF, then pick the file from Files. Each page is added as a page in a notebook.
-
Study it. Red Sheet hides the colored answers, and in Edit you can box any other words. Reveal, then mark ○ or ×.
-
Turn on iCloud Sync in Settings to use the same pages on iPhone and iPad. Your pages, edits and grades sync through your own iCloud.
-
Use Apple Pencil on iPad. Study on the big screen, and draw boxes and markers with Apple Pencil.
Good to know
- Back up for free. Export every notebook as one file to Files or anywhere else, and restore from it on a new iPhone.
- Offline. Adding pages, hiding, grading and review run on your device. Only iCloud sync uses the internet.
Other ways to do it
- PDF annotators can highlight, but they don’t hide the answers and quiz you.
- Printing the PDF and using a plastic sheet works, with paper and a pen.
Questions people ask
Can I use notes from another app?
Yes. Export them as a PDF, then import the PDF into Red Sheet from Files. Each page becomes a page you can hide and quiz on.
Does syncing upload my pages to W Lab?
No. W Lab never sees your pages and has no server to receive them. Sync uses your own iCloud, and it is the only part of the app that uses the internet.
