# 适趣AI中文 vs 宇宙星图

The clearest difference is rating: 宇宙星图 at 4.2 against 适趣AI中文's 3.7. 宇宙星图 also leads on iOS requirement (13.0 vs 15.0). 适趣AI中文's advantage is ads (none vs shown) and update cadence (weekly vs every 2 months). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. 适趣AI中文 sells 7 one-off in-app purchases and 宇宙星图 sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

宇宙星图 holds the better App Store score, 4.2 against 3.7. That said, the two scores are not equally well evidenced: 适趣AI中文 has 41 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 82% of 适趣AI中文's written reviews are positive against 80% of 宇宙星图's, so the app with the better star average is not the one people write more warmly about.

适趣AI中文 ships an update weekly, 宇宙星图 every 2 months. The most recent releases landed on October 12, 2026 and October 11, 2026 respectively.
