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) research—the 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 WPM—start 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)—presenting 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: • ORP Highlighting - Words offset to your eye's sweet spot. Read 3x faster without trying. • EPUB/PDF Support - Import any book. Proper chapter detection. No weird parsing bugs. • Customizable Speed - Start at your comfort zone. Push to 1000+ WPM when you're ready. • Dark Mode Native - Black background. Easy on your eyes during those 2am reading sessions. • Progress Syncing - Pick up where you left off. Every book. Every time. • 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.

Still reading like it's 2005? Your brain deserves an upgrade. Blitzr is an RSVP speed reader for PDFs, EPUBs, Word docs, and web articles. It flashes one word at a time in a fixed spot — no eye-jumping, no losing your place — so you read faster, with sharper focus. - Your pace: start at 250 WPM, climb past 600 as your brain adapts - Smart pauses at sentence and clause boundaries — speed without sacrificing comprehension - One reader, every format: EPUB, PDF, .docx, web articles, plain text, and free Project Gutenberg titles How RSVP Works Your eyes normally jump between words and back over what you've read — that's what slows you down. RSVP (Rapid Serial Visual Presentation) shows one word at a time in the same spot, so your eyes stop hunting and your focus locks in. Smart pauses at sentence and clause boundaries keep the meaning intact, even as you speed up. Whether you're a student drowning in PDFs or a professional chasing deadlines, Blitzr turns you into an accelerated reader — minus the stress. One Reader, Every Format - EPUB books, with inline illustrations - PDFs, including textbooks and research papers - Word documents (.docx), with inline images - Web articles — just share a link to Blitzr - Plain text and free Project Gutenberg titles - Clean, minimal interface built for long reading sessions Use Cases - Study PDFs — research papers, textbook chapters, lecture notes - Read EPUB books — your library, or free Gutenberg titles - Articles & web text — share a link, speed-read it - Work documents — reports, briefs, Word docs Train Your Brain (Yes, Really) - Improve focus and comprehension - Build consistent reading habits - Finish books faster than ever - Spend less time scrolling, more time learning Features That Matter - Adjustable speed controls (go slow or go supersonic) - Multiple modes: RSVP, Highlight, Classic, and Teleprompter - Distraction-free interface - Fully private — your data stays on your device FAQ Q: Will speed reading hurt my comprehension? A: Not if you build up gradually. Start at a pace you fully understand, then nudge the speed up only when you can still follow along. The built-in pauses do a lot of the work for you. Q: What if I can't keep up? A: Just lower the WPM. Blitzr is yours to pace — slow and steady is how the habit builds. Q: Does Blitzr work offline? A: Yes. Imported files stay on your device, and your reading data is fully private. Getting Started 1. Import a file (EPUB, PDF, Word, or text) or share an article to Blitzr 2. Set your reading speed 3. Start your RSVP journey No complicated setup. No learning curve. Blitzr is more than an EPUB reader or RSVP app — it's your shortcut to reading smarter, faster, and better. Download now and finally win the battle against your reading list. — PDF rendering powered by Xodo PDF Reader and Editor.
