## App Description Reading shouldn't be this hard. SpeedReader is a free Safari extension that lets you speed read any web page using RSVP (Rapid Serial Visual Presentation) — showing one word at a time at a controlled pace. For neurodivergent readers — people with ADHD, dyslexia, or other processing differences — traditional reading is exhausting. Eyes jump between lines, focus drifts mid-paragraph, and articles get abandoned halfway through. RSVP removes the cognitive overhead of eye tracking and line scanning, so your brain just processes. **How it works** Tap the SpeedReader icon in Safari's toolbar. The article text is extracted automatically and words appear one at a time with a highlighted focus point. Tap anywhere to pause, tap again to resume. That's it. **Features** • Focus-point highlighting — each word highlights its optimal recognition point, the letter your eye naturally anchors to • Context preview — pause and see the surrounding sentence to re-orient quickly • Punctuation pacing — periods and commas add natural micro-pauses so content flows like speech • Speed control — 100 to 600 words per minute • OpenDyslexic font — toggle the dyslexia-friendly font with one tap • Light and dark mode — follows your system theme or override manually • Keyboard shortcuts — on Mac and iPad: Space to play/pause, arrows to navigate • Text selection fallback — select any text on a page and speed read just that • Works entirely offline — no data leaves your device No accounts. No subscriptions. No tracking. Free and open source.
