# Epub Reader vs CHM+

The clearest difference is rating: Epub Reader at 4.5 against CHM+'s 3.0. Epub Reader also leads on ratings volume (11K vs 2) and update cadence (every 2 weeks vs every 6 weeks). CHM+'s advantage is review sentiment (83% vs 55%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Epub Reader sells 4 in-app purchases, starting at $3.99 per year and CHM+ sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Epub Reader holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: Epub Reader has 11K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 55% of Epub Reader's written reviews are positive against 83% of CHM+'s, so the app with the better star average is not the one people write more warmly about.

Epub Reader ships an update every 2 weeks, CHM+ every 6 weeks. The most recent releases landed on October 21, 2026 and October 12, 2026 respectively.
