About

Pressly Speed Reader

Read full description

Most speed reading apps give you a play button. Pressly gives you control. Pressly uses RSVP-style reading — one word at a time, fixed to a single focus point — so your eyes never move and your focus never breaks. But speed is not the goal. Comprehension is. BUILT AROUND MEANING, NOT JUST MOTION Text inside double quotation marks automatically italicizes during reading. Dialogue shifts. Quoted phrases stand apart. Spoken words separate from narration. You feel the change in tone without losing your place — a detail no other speed reader has. Smart pauses at punctuation and extra time for longer words give each sentence the rhythm it was written with. Optional context words keep surrounding text visible. ORP alignment anchors each word at its natural recognition point. When the same word appears back-to-back, it grows progressively — a subtle visual signal that keeps comprehension engaged at speed. YOU ARE ALWAYS IN CONTROL Hold to read. Release to pause. Lock playback with two fingers for hands-free reading. Tap forward or back to move word by word. Tap the top area to step back. Set your WPM, tune your pauses, choose a theme, adjust your font — then read. Tap the current word while reading to instantly look it up in your device's dictionary — without losing your place. YOUR FILES, YOUR LIBRARY Pressly is a reading tool, not an ebook store. Import your EPUB, PDF, and TXT files, or paste notes, articles, drafts, and copied text directly. Everything stays on your device. No account. No cloud. No subscription to a catalog. A built-in sample book is included — start reading immediately, no import needed.
