Verdict
The clearest difference is rating: Chess ∙ at 4.5 against Chess Duel's 3.3. Chess ∙ also leads on ratings volume (205K vs 7) and chart position (#72 vs unranked). Chess Duel's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, update cadence, in-app purchases 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. Neither carries in-app purchases, so what you see is what you pay.
Chess ∙ holds the better App Store score, 4.5 against 3.3. That said, the two scores are not equally well evidenced: Chess ∙ has 205K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 56% of Chess ∙'s written reviews are positive against 68% of Chess Duel's, so the app with the better star average is not the one people write more warmly about.
Chess ∙ ships an update every 4 months, Chess Duel every 5 months. The most recent releases landed on October 18, 2026 and October 13, 2026 respectively.
