Read Rocket gives you three powerful, science-backed ways to read faster and stay focused — whether you're powering through textbooks, catching up on articles, or flying through your reading list. THREE WAYS TO READ Flash Mode displays one word at a time at a fixed focal point, eliminating the eye movements that account for most of your reading time. Set your own pace and watch your speed climb. Scroll Mode adds a guided highlight that moves through your document at a steady rhythm, keeping your attention locked and preventing the backtracking that slows you down. Speak Mode pairs high-quality AI text-to-speech with a synchronized visual highlight, engaging both your eyes and ears for stronger comprehension and retention. IMPORT ALMOST ANYTHING Bring in PDFs, EPUBs, Word documents, web articles, plain text, Markdown, HTML, RTF, OpenDocument files, and more — Read Rocket strips away the clutter so you can focus on what matters. Save articles straight from Safari or any app using your device's share menu, and they're instantly ready to read.

Export your library to take your files where you need them. BUILT FOR APPLE Read Rocket is a native app designed for iPhone, iPad, and Mac.
