Verdict
The clearest difference is rating: CHMate at 3.9 against CHM+'s 3.0. CHMate also leads on ads (none vs shown) and ratings volume (20 vs 2). CHM+'s advantage is review sentiment (71% vs 55%) and iOS requirement (15.0 vs 26.0). On price, in-app purchases, monetization model and device support 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+ sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
CHMate holds the better App Store score, 3.9 against 3.0. 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 71% of CHM+'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+ every 6 weeks. The most recent releases landed on November 6, 2026 and November 5, 2026 respectively.
