The most successful people in the world read more than everyone else. Yet most of us can't finish a single book, not because we lack time, but because social media, doom-scrolling, and endless notifications keep pulling us away. ReadLock helps you take back your attention. Set a reading session, choose the apps and website categories that distract you most, and ReadLock locks them using Screen Time so your phone stops competing with your book. When your session ends, update your reading progress or notes, and ReadLock's AI scores your comprehension before your apps unlock. No skimming. No faking it. Just real reading. "Just one more scroll" becomes "just one more page." It works with any book format: paperback, hardcover, e-book, or PDF. No special reader required. Key Features * Distraction Locking (Screen Time): Lock selected apps and distracting website categories during your reading sessions. When a locked app is opened, the ReadLock shield screen appears. * AI Comprehension Scoring: After each session, write a short note on what you read. ReadLock's AI compares your notes against your pages and scores your focus and understanding before your apps unlock. You can't fake your way through. * AI Summary Suggestions: Not sure how to capture what you read? ReadLock's AI rewrites your notes into a cleaner, sharper summary — turning scattered thoughts into real understanding. * Book Scanning & Search: Add any book instantly by scanning the cover or searching the title. Your reading journey starts in seconds. * Works with Any Book Format: Track progress and take chapter notes for both physical and digital books. No special reader required. * Flexible Reading Sessions: Set reading windows for morning, afternoon, or evening and build a consistent daily routine. * Progress Tracking: Update pages read, mark chapters as completed, and watch your reading habit grow day by day. * Notes & Key Takeaways: Capture chapter notes and important lessons as you read. AI sharpens them after every session. * Book Library: Add books by scan or search, organize by category, and pick up right where you left off. * Habit Building: Streaks, session history, and gentle reminders to make reading stick as a long-term habit. How to Use ReadLock 1. Sign in with Google or Apple, or continue as a guest—your choice. 2. Add your current book by scanning the cover or searching the title. 3. Tap Locked Apps → Add, grant Screen Time permission, and select the apps, categories, or websites you want to block. 4. Tap Set Daily Reading Target and pick your reading window. 5.

DocDance (DocumentDance) is not a traditional PDF reader. It is a visual reading tool designed for people who struggle with dense text—or simply have too much of it to read. Instead of forcing your eyes to scan endless black paragraphs, DocDance restructures text visually. Key terms are detected and transformed into color-coded, size-weighted highlights, guiding your attention naturally through each paragraph. Your brain stops hunting for meaning. It just follows it. Why DocDance is different Most reading apps focus on layout. DocDance focuses on cognition. By turning important words into visual anchors, DocDance helps you read faster, stay focused longer, and retain more—without speed-reading tricks or summaries. Built for real readers • People with ADHD or attention difficulties • Readers with dyslexia or visual fatigue • Students facing heavy academic reading • Professionals reviewing long reports, specs, or research • Anyone who needs to read a lot, quickly, and clearly Read anything • PDF, EPUB and Word documents • Plain text • Web articles via URL • Read aloud with on-device text-to-speech Total control over your reading style • Color themes tuned for focus, not decoration • Adjustable keyword density • Dynamic text sizing for emphasis • Animation speed from calm to turbo • Resume reading exactly where you stopped DocDance adapts to how your brain reads—not the other way around. Privacy-first by design All reading effects run locally on your device. No accounts. No uploads. No tracking. If traditional reading feels slow, exhausting, or overwhelming, DocDance offers a new way in. Not more text. Better reading. MEMBERSHIP Unlock everything with Annual, an auto-renewing yearly subscription that starts with a 3-day free trial for eligible new subscribers, or Lifetime, a one-time purchase. If you got DocDance before it moved to the subscription model, Lifetime is already unlocked for you. Payment is charged to your Apple Account when you confirm the purchase; with the free trial, you are charged when the trial ends unless you cancel at least 24 hours before it ends. Annual renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings.
