Verdict
The clearest difference is rating: DarknessBot at 4.8 against ChessBot's 4.0. DarknessBot also leads on ratings volume (1.9K vs 34) and iOS requirement (13.0 vs 18.0). ChessBot's advantage is review sentiment (67% vs 58%). On price, update cadence, ads and in-app purchases 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. ChessBot sells 3 in-app purchases, starting at $1.99 per month and DarknessBot sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
DarknessBot holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: DarknessBot has 1.9K ratings behind it against 34, so its average is the more settled of the two. Written reviews complicate that: 67% of ChessBot's written reviews are positive against 58% of DarknessBot's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 8, 2026 and October 17, 2026 respectively.
