# 理想同学 vs 暗礁助手

The clearest difference is rating: 暗礁助手 at 5.0 against 理想同学's 4.4. 理想同学's advantage is in-app purchases (none vs 3) and review sentiment (68% vs 43%). On price, ads and device support there is nothing between them.

Both are free to download. 暗礁助手 sells 3 in-app purchases, starting at $0.99 per month. 理想同学 asks for nothing beyond the download.

暗礁助手 holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: 理想同学 has 17 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 68% of 理想同学's written reviews are positive against 43% of 暗礁助手's, so the app with the better star average is not the one people write more warmly about.

理想同学 ships an update fortnightly, 暗礁助手 monthly. The most recent releases landed on October 18, 2026 and September 27, 2026 respectively.
