# Tide Pro vs 水印猫

The clearest difference is ads: 水印猫 at none against Tide Pro's shown. 水印猫 also leads on update cadence (fortnightly vs every 2 months) and ratings volume (41 vs 3). Tide Pro's advantage is rating (5.0 vs 4.6). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Tide Pro sells 2 one-off in-app purchases and 水印猫 sells 9 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Tide Pro holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: 水印猫 has 41 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 38% of Tide Pro's written reviews are positive against 43% of 水印猫's, so the app with the better star average is not the one people write more warmly about.

Tide Pro ships an update every 2 months, 水印猫 fortnightly. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
