# 真好算 vs 拦截猫

The clearest difference is rating: 真好算 at 5.0 against 拦截猫's 3.9. 真好算 also leads on monetization model (free vs freemium). 拦截猫's advantage is ratings volume (105 vs 3) and review sentiment (84% vs 67%). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 真好算 sells 1 one-off in-app purchase and 拦截猫 sells 4 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

真好算 holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: 拦截猫 has 105 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 67% of 真好算's written reviews are positive against 84% of 拦截猫's, so the app with the better star average is not the one people write more warmly about.

真好算 ships an update monthly, 拦截猫 every 2 weeks. Both last shipped on September 23, 2026.
