# 新知卫星地图 vs Ai 绘画

The clearest difference is review sentiment: Ai 绘画 at 100% against 新知卫星地图's 56%. Ai 绘画 also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.0). 新知卫星地图's advantage is rating (4.6 vs 3.0) and ratings volume (74 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. 新知卫星地图 sells 9 in-app purchases, starting at $3.49 per month and Ai 绘画 sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

新知卫星地图 holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: 新知卫星地图 has 74 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 56% of 新知卫星地图's written reviews are positive against 100% of Ai 绘画's, so the app with the better star average is not the one people write more warmly about.

新知卫星地图 ships an update weekly, Ai 绘画 fortnightly. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
