# SMS Spam Filter vs Spam Text Blocker

The clearest difference is rating: Spam Text Blocker at 4.4 against SMS Spam Filter's 3.0. Spam Text Blocker also leads on update cadence (every 6 weeks vs every 15 months) and ratings volume (137 vs 2). SMS Spam Filter's advantage is in-app purchases (none vs 2) and review sentiment (82% vs 50%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Spam Text Blocker sells 2 in-app purchases, starting at $3.99 per month. SMS Spam Filter asks for nothing beyond the download.

Spam Text Blocker holds the better App Store score, 4.4 against 3.0. That said, the two scores are not equally well evidenced: Spam Text Blocker has 137 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 82% of SMS Spam Filter's written reviews are positive against 50% of Spam Text Blocker's, so the app with the better star average is not the one people write more warmly about.
