We check your book and ask for confirmation before using a credit. Finish and replay an accepted narration for 90 days. Changing voice uses another credit. Unused credits do not roll over; yearly billing releases credits monthly, not all at once. Internet is required for cloud narration. On-device narration remains available separately. YOUR BOOKS, YOUR PACE LeafTok is a reader for books you import, not an audiobook catalog. Cloud plans are available in supported storefronts. Existing Pro plans keep their purchased benefits; Cloud 5 is an optional upgrade. CHAPTER SUMMARIES Explore summaries by chapter and a separate book overview. Cloud summaries require an eligible paid subscription, account sign-in and available usage allowance. Trials and Family Sharing are not included. AI-generated summaries may contain mistakes. Subscriptions renew automatically unless canceled in App Store account settings. The App Store shows the price and billing period before purchase.

FlowSpeedReader is a powerful speed reading app that uses Rapid Serial Visual Presentation (RSVP) to help you consume text faster than ever before. Whether you're a student, professional, or avid reader, FlowSpeedReader trains your brain to process words at incredible speeds — all while maintaining comprehension. HOW IT WORKS RSVP displays one word (or a group of words) at a time in a fixed position, eliminating the eye movements (saccades) that waste up to 30% of traditional reading time. Your brain focuses purely on processing meaning. Research shows comprehension remains high even above 500 WPM. IMPORT ANYTHING • Paste or type text directly • Import from Safari using the Share Sheet extension • Fetch and extract articles from any URL • Import files: PDF, DOCX, TXT, RTF, Pages, CSV • Scan physical documents with Camera OCR • Load from clipboard (text or URLs) BEAUTIFUL THEMES & FONTS Choose from multiple gorgeous themes — including dark mode variants — and select from 8 premium fonts. FlowSpeedReader looks stunning and feels great to use. TEXT-TO-SPEECH (TTS) Listen while you read. FlowSpeedReader features a full TTS engine with: • Multi-language support (Arabic, Hebrew, Farsi, Urdu, and more) • Automatic language detection • Multiple voice options per language (Standard, Enhanced, Premium) • Synchronized word highlighting during audio playback EYE TRACKING (iPhone X and later) FlowSpeedReader uses the TrueDepth camera to detect when you look away and automatically pauses your reading session. Configurable sensitivity, pause delay, and auto-resume keep you in the zone. FOCUS TIMER (POMODORO) Stay productive with built-in Pomodoro-style focus sessions. Set custom focus and break durations, and let the app manage your reading schedule.
