Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
