BookBay is the AppVitamins fleet's digital bookstore and reader. Browse curated ebooks (EPUB and PDF), interactive Smart Books you read right in your browser, formula-driven Intelligent Spreadsheets, kids' read-along adventures and audiobooks across six categories: Productivity, Finance, Health, Self-Development, Kids and Reference.
Every product has a free sample you can read instantly — no signup. The in-browser reader includes four reading themes (dark, sepia, paper and high-contrast), serif / sans / dyslexia-friendly typefaces, adjustable text size and line spacing, a table of contents, in-book search, bookmarks and auto-saved reading progress so you can pick up exactly where you left off.
BookBay Pro turns the reader into a study tool. Select any passage to highlight it in four colours and attach a note, then export all of your highlights and notes to Markdown, CSV, JSON or print to PDF — perfect for moving your best ideas into Obsidian, Notion or your own notes. Pro also unlocks a gamified reading-stats dashboard with day streaks, a weekly reading goal, achievement badges and a CSV export of your reading history. Everything is stored privately on your device.
Paid files are never hosted publicly. EPUBs, PDFs, spreadsheets and audiobooks arrive as secure, expiring download links by email, and Smart Books unlock with a license key in My Library. Our checkout partner is the merchant of record and calculates any VAT or sales tax for your country at checkout. Choose your country to preview approximate local-currency prices.
