# EPUB Reader vs Calibre ebook reader

The clearest difference is ads: EPUB Reader at none against Calibre ebook reader's shown. EPUB Reader also leads on review sentiment (82% vs 67%) and ratings volume (54 vs 13). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. EPUB Reader sells 7 in-app purchases, starting at $2.99 per month and Calibre ebook reader sells 4 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Written reviews complicate that: 82% of EPUB Reader's written reviews are positive against 67% of Calibre ebook reader's, so the app with the better star average is not the one people write more warmly about.
