# Sakk vs Chess World Master

Sakk also leads on monetization model (ad-supported vs free with in-app purchases) and update cadence (every 3 weeks vs every 2 months). Chess World Master's advantage is rating (4.3 vs 2.5) and ratings volume (32 vs 2). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Chess World Master holds the better App Store score, 4.3 against 2.5. That said, the two scores are not equally well evidenced: Chess World Master has 32 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 91% of Sakk's written reviews are positive against 42% of Chess World Master's, so the app with the better star average is not the one people write more warmly about.

Sakk ships an update every 3 weeks, Chess World Master every 2 months. The most recent releases landed on October 8, 2026 and October 14, 2026 respectively.
