You hate speed reading apps. We get it. They flash words at you like a slot machine. Your eyes hurt after 5 minutes. You retain nothing. It's exhausting. SprintRead is different. The Science: ORP Technology We built this around Optimal Recognition Point (ORP) researchβthe exact spot in a word where your brain processes it fastest. Here's what actually happens: - Your eye naturally wants to land slightly left of center in each word - Traditional speed readers ignore this. They blast words at you centered. - Your brain fights to adjust every single time - Result: Fatigue, headaches, giving up SprintRead highlights the ORP in every word. Your eye knows exactly where to look. No fighting. No fatigue. What You Get Read Faster, Effortlessly - 3x your normal reading speed within days - Adjustable WPMβstart at 250, work up to 1000+ - Your eyes will thank you Your Library, Your Rules - Import any EPUB or PDF - Synced progress across all your books - Pick up exactly where you left off Actually Good Design - Black background, minimal UI (your eyes again) - Customizable highlight colors - Built for reading, not looking pretty in screenshots Zero B******t - No accounts - No subscriptions hidden behind "free trial" - No "gamification" or achievement badges - Just you and your books The Reading Experience SprintRead uses a technique called Rapid Serial Visual Presentation (RSVP)βpresenting one word at a time. But unlike other RSVP apps, we don't center-align words like idiots. We offset each word based on its length and structure. Your eye lands on the ORP automatically. You read faster without trying harder. It's like the difference between: - Fighting through traffic (other speed readers) - Highway with no exits (SprintRead) Who This Is For You if: - You have 47 books in your "to read" pile - You hate that you're a slow reader - You've tried other speed reading apps and rage-deleted them - You actually want to retain what you read Not for you if: - You read 2 books a year and that's fine - You think "the journey is the destination" about reading - You prefer audiobooks (no judgment, just wrong app) What's Inside: β’ ORP Highlighting - Words offset to your eye's sweet spot. Read 3x faster without trying. β’ EPUB/PDF Support - Import any book. Proper chapter detection. No weird parsing bugs. β’ Customizable Speed - Start at your comfort zone. Push to 1000+ WPM when you're ready. β’ Dark Mode Native - Black background. Easy on your eyes during those 2am reading sessions. β’ Progress Syncing - Pick up where you left off. Every book. Every time. β’ No Account Required - Download, import, read. That's it. This is version 1.0. It's not perfect. But it works, it's fast, and it won't make your eyes bleed. Try it. Read a chapter. See if you can double your speed by next week.
