People who read everything in captions (TikTok, Reels) have lost the ability to sit down and read actual books, needing a reading app that matches that same rapid, word-by-word rhythm.

Existing speed-reading apps are designed as productivity tools (text paste, no library) and lack a book-centric experience with public-domain content and local privacy.

App Concept

BookTap Reader

BookTap Reader is a mobile reading app that uses RSVP (word-by-word flashing) to let you read full books at your own pace, just like you read TikTok captions. It comes with a built-in library of public-domain classics, supports PDF import, and keeps everything local and private.

Key Features

RSVP reading mode with adjustable speed
Built-in library of free public-domain classics
PDF import for personal books
No account required, all data stays on device

Target Users: Individual readers who consume short-form video but struggle to read traditional books, aged 18-45.

Revenue Model: Freemium: free with basic RSVP and public-domain library; $5/month premium for custom backgrounds, adjustable speed presets, reading insights, and bookmarking.
