Verdict
The clearest difference is rating: CHM Reader at 5.0 against CHMate's 3.9. CHM Reader also leads on iOS requirement (16 vs 26.0). CHMate's advantage is ratings volume (20 vs 2) and review sentiment (55% vs 43%). 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 CHM Reader sells 3 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.
CHM Reader holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: CHMate has 20 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 55% of CHMate's written reviews are positive against 43% of CHM Reader's, so the app with the better star average is not the one people write more warmly about.
CHMate ships an update every 2 weeks, CHM Reader monthly. The most recent releases landed on November 6, 2026 and October 31, 2026 respectively.
