# CHMate vs tiReader

The clearest difference is rating: tiReader at 4.5 against CHMate's 3.9. tiReader also leads on ratings volume (648 vs 20) and review sentiment (67% vs 55%). CHMate's advantage is update cadence (every 2 weeks vs every 6 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. CHMate sells 1 one-off in-app purchase and tiReader sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

tiReader holds the better App Store score, 4.5 against 3.9. That said, the two scores are not equally well evidenced: tiReader has 648 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 67% of tiReader's.

CHMate ships an update every 2 weeks, tiReader every 6 weeks. The most recent releases landed on October 21, 2026 and October 13, 2026 respectively.
