# CHM+ vs CHM Reader

The clearest difference is rating: CHM Reader at 5.0 against CHM+'s 3.0. CHM Reader also leads on ads (none vs shown). CHM+'s advantage is review sentiment (83% vs 43%). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

Both are free to download. CHM+ 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 3.0. Both are backed by a comparable volume of ratings — 2 and 1 respectively. Written reviews complicate that: 83% of CHM+'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.

CHM+ ships an update every 6 weeks, CHM Reader every 3 weeks. The most recent releases landed on September 26, 2026 and September 25, 2026 respectively.
