# 专去水印 vs 纳米AI

The clearest difference is review sentiment: 专去水印 at 95% against 纳米AI's 54%. 专去水印 also leads on rating (4.6 vs 4.3) and iOS requirement (8.0 vs 15.0). 纳米AI's advantage is update cadence (weekly vs monthly) and ratings volume (211 vs 10). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 专去水印 sells 5 one-off in-app purchases and 纳米AI sells 14 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

专去水印 holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: 纳米AI has 211 ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 95% of 专去水印's written reviews are positive against 54% of 纳米AI's.

专去水印 ships an update monthly, 纳米AI weekly. The most recent releases landed on October 16, 2026 and October 20, 2026 respectively.
