Your phone was designed to scatter your attention. FocusWord reverses the equation. FocusWord presents your books one word at a time on a full dark screen. Each word is positioned at its Optimal Recognition Point. Smart Slowing pauses naturally at sentence boundaries. Your phone becomes a place of focus instead of distraction. No willpower required. No fighting notifications. Just you and the words. IMPORT YOUR BOOKS Import any EPUB from your device. Navigate chapters. Track your reading progress. This is a real reading app for people who actually read books. READ AT YOUR PACE Adjust speed from 100 to 1000 WPM — whatever pace lets you focus completely. Start slow, build up naturally. Smart Slowing adapts to punctuation so the rhythm feels like reading, not a metronome. DESIGNED FOR FOCUS One word. Full screen. Zero distractions. Auto-hiding controls disappear within milliseconds. Gesture-only interaction while reading. The app becomes invisible so the book can take over. BUILT FOR BRAINS THAT WORK DIFFERENTLY ADHD-friendly design. VoiceOver support. Right-to-left reading. Reduce Motion compatibility. Focus isn't a character trait you lack — it was just never properly supported. BUY ONCE. READ FOREVER. No subscriptions. No ads. No dark patterns. No account required. One purchase, unlimited books, every feature. Your books stay on your device. Your data stays yours.
