# Lios Calibre Viewer vs EPUB Reader

The clearest difference is price: EPUB Reader at Free against Lios Calibre Viewer's $2.99. EPUB Reader also leads on rating (4.6 vs 4.3) and ratings volume (54 vs 3). Lios Calibre Viewer's advantage is in-app purchases (none vs 7) and review sentiment (100% vs 82%). On update cadence, ads and device support there is nothing between them.

EPUB Reader is free to download; Lios Calibre Viewer costs $2.99 up front. EPUB Reader sells 7 in-app purchases, starting at $2.99 per month. Lios Calibre Viewer asks for nothing beyond the download.

EPUB Reader holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: EPUB Reader has 54 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of Lios Calibre Viewer's written reviews are positive against 82% of EPUB Reader's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 5 days. The most recent releases landed on October 24, 2026 and October 27, 2026 respectively.
