# 兴趣岛 vs 大脑营行

The clearest difference is ads: 兴趣岛 at none against 大脑营行's shown. 兴趣岛 also leads on rating (4.3 vs 4.0) and ratings volume (46 vs 4). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. 兴趣岛 sells 14 one-off in-app purchases and 大脑营行 sells 11 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

兴趣岛 holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: 兴趣岛 has 46 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 86% of 兴趣岛's written reviews are positive against 90% of 大脑营行's, so the app with the better star average is not the one people write more warmly about.

兴趣岛 ships an update every 2 weeks, 大脑营行 every 3 weeks. The most recent releases landed on October 1, 2026 and September 22, 2026 respectively.
