Read Smarter
Free · Designed for iPad. Not verified for macOS.
Your AI reading companion for PDF & EPUB. R2D2 quizzes you on every chapter and uses active recall so you actually remember what you read — long after the last page.
Read once. Remember forever.
R2D2 Reader is your AI reading companion for PDF and EPUB — named for the galaxy's most loyal droid. It reads every chapter alongside you, quizzes you on what matters, and shows you, page by page, what you're about to forget. So the books you love actually stay
with you.
Most books are read and forgotten. R2D2 fixes that with active recall — the most proven way to remember what you read.
WHAT R2D2 DOES
— Reads with you. Open any PDF or EPUB in a clean, distraction-free reader built for deep focus.
— Quizzes every chapter. Finish a chapter and R2D2 turns it into five real questions, graded instantly. No flashcards to write, no decks to manage.
— Tracks what you remember. A colour-coded memory heatmap of the whole book shows what's strong, what's fading, and what to review next. Tap any cell to jump straight there.
— Keeps the habit. A daily streak, weekly minutes, and a full year of reading days keep you turning pages.
HOW IT WORKS
1. Read — open your book and read, distraction-free.
2. Quiz — R2D2 turns the chapter into questions the moment you finish.
3. Remember — review the weak pages first, before they fade for good.
BUILT FOR BOOK LOVERS
— PDF and EPUB — bring the books and documents you already have.
— iPad, iPhone, and Mac, with your library in sync.
