# 儿童IQ益智图书 vs Chess Light

The clearest difference is rating: Chess Light at 4.7 against 儿童IQ益智图书's 4.0. Chess Light also leads on ratings volume (6 vs 1). 儿童IQ益智图书's advantage is review sentiment (100% vs 79%) and update cadence (every 5 months vs every 18 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 儿童IQ益智图书 sells 1 one-off in-app purchase and Chess Light sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Chess Light holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Chess Light has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of 儿童IQ益智图书's written reviews are positive against 79% of Chess Light's, so the app with the better star average is not the one people write more warmly about.

儿童IQ益智图书 ships an update every 5 months, Chess Light every 18 months. The most recent releases landed on September 30, 2026 and September 26, 2026 respectively.
