# 水印大师 vs LanStudio VPN

The clearest difference is rating: 水印大师 at 5.0 against LanStudio VPN's 4.4. 水印大师 also leads on update cadence (fortnightly vs every 2 months) and review sentiment (44% vs 27%). LanStudio VPN's advantage is ratings volume (127 vs 13). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 水印大师 sells 10 in-app purchases, starting at $3.99 per 7 days and LanStudio VPN sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

水印大师 holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: LanStudio VPN has 127 ratings behind it against 13, so its average is the more settled of the two. Written reviews point the same way: 44% of 水印大师's written reviews are positive against 27% of LanStudio VPN's.

水印大师 ships an update fortnightly, LanStudio VPN every 2 months. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
