# AnyAUTH vs Smart Spam Filter

The clearest difference is review sentiment: Smart Spam Filter at 98% against AnyAUTH's 14%. Smart Spam Filter also leads on ratings volume (9 vs 1). AnyAUTH's advantage is rating (5.0 vs 4.4) and in-app purchases (none vs 2). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Smart Spam Filter sells 2 in-app purchases, starting at $2.99 per month. AnyAUTH asks for nothing beyond the download.

AnyAUTH holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Smart Spam Filter has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 14% of AnyAUTH's written reviews are positive against 98% of Smart Spam Filter's, so the app with the better star average is not the one people write more warmly about.

AnyAUTH ships an update every 3 weeks, Smart Spam Filter every 2 weeks. The most recent releases landed on September 11, 2026 and September 24, 2026 respectively.
