Verdict
The clearest difference is review sentiment: EPUB Reader at 77% against CHMate's 55%. EPUB Reader also leads on rating (4.2 vs 3.9) and ratings volume (809 vs 20). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. CHMate sells 1 one-off in-app purchase and EPUB Reader sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
EPUB Reader holds the better App Store score, 4.2 against 3.9. That said, the two scores are not equally well evidenced: EPUB Reader has 809 ratings behind it against 20, so its average is the more settled of the two. Written reviews point the same way: 55% of CHMate's written reviews are positive against 77% of EPUB Reader's.
CHMate ships an update every 2 weeks, EPUB Reader every 3 weeks. The most recent releases landed on October 9, 2026 and October 7, 2026 respectively.
