# SMSCat vs 拦截盾

The clearest difference is review sentiment: 拦截盾 at 67% against SMSCat's 33%. 拦截盾 also leads on iOS requirement (15.0 vs 17.0). SMSCat's advantage is rating (4.4 vs 4.0). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. SMSCat sells 6 in-app purchases, starting at $0.99 per month and 拦截盾 sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

SMSCat holds the better App Store score, 4.4 against 4.0. Both are backed by a comparable volume of ratings — 34 and 25 respectively. Written reviews complicate that: 33% of SMSCat's written reviews are positive against 67% of 拦截盾's, so the app with the better star average is not the one people write more warmly about.

SMSCat ships an update every 8 days, 拦截盾 fortnightly. The most recent releases landed on October 24, 2026 and October 19, 2026 respectively.
