# KMate vs Common Reader

The clearest difference is update cadence: Common Reader at every 2 days against KMate's fortnightly. KMate's advantage is review sentiment (100% vs 80%) and iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. KMate sells 3 in-app purchases, starting at $0.99 per month and Common Reader sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

KMate ships an update fortnightly, Common Reader every 2 days. Both last shipped on October 25, 2026.
