Your attention is under siege. Every scroll trains your brain to expect novelty faster — and focus less. Devoro flips the script: same phone, same spare moments, but now they train your focus instead of destroying it. Devoro uses RSVP (Rapid Serial Visual Presentation) to display one word at a time at a single fixed point. Your eyes can't wander. Your attention has exactly one target. It's meditation for reading — and when your mind drifts and you rewind, that's not failure. That's a rep. LEARN Curious about something? Type any topic — philosophy, nutrition, how satellites work — and Devoro generates articles just for you. Every article ends with a quiz to test retention and lock in what you learned. Curiosity is the fuel. Attention is the muscle. PRACTICE Not sure where to start? Browse 200+ pre-built articles across 15 topics and build your focus habit with guided speed reading sessions. Quizzes after each article prove you retained it — not just read it. READ Bring your own content. Paste a URL, upload a PDF or EPUB, or drop in plain text. Devoro serves it back at whatever pace you choose — from a comfortable 200 WPM to a blazing 1500. WHAT MAKES DEVORO DIFFERENT: FOCUS TRAINING Most reading apps help you go fast. Devoro trains you to stay focused. The effort isn't a bug — it's the entire point. Five minutes a day on your commute, lunch break, or before bed. Replace the scroll with a training rep. FEATURES • Adjustable speed: 50–1500 WPM • Comprehension quizzes after every article • AI-generated articles on any topic • Import URLs, EPUBs, PDFs, and plain text • Multi-device sync • Beautiful shareable certificates for meaningful speed & retention milestones • 4 themes: dark, midnight, sepia, light • Supports 12 languages Train your attention. Feed your curiosity. Terms of Service: https://devoro.app/en/terms/ Privacy Policy: https://devoro.app/en/privacy/
