Verdict
The clearest difference is rating: Summit Reader at 4.8 against CHMate's 3.8. Summit Reader also leads on review sentiment (86% vs 55%) and ratings volume (1.3K vs 20). CHMate's advantage is ads (none vs shown). 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 Summit Reader sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Summit Reader holds the better App Store score, 4.8 against 3.8. That said, the two scores are not equally well evidenced: Summit Reader has 1.3K 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 86% of Summit Reader's.
CHMate ships an update every 2 months, Summit Reader every 3 weeks. The most recent releases landed on September 21, 2026 and September 25, 2026 respectively.
