Verdict
The clearest difference is rating: IfFound at 4.0 against SMS Spam Blocker's 3.3. IfFound also leads on update cadence (every 8 months vs every 23 months) and ratings volume (29 vs 4). SMS Spam Blocker's advantage is review sentiment (70% vs 38%) and iOS requirement (11.0 vs 17.6). On ads, in-app purchases and device support there is nothing between them.

SMS Spam Blocker costs $1.99 and IfFound $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
IfFound holds the better App Store score, 4.0 against 3.3. That said, the two scores are not equally well evidenced: IfFound has 29 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 70% of SMS Spam Blocker's written reviews are positive against 38% of IfFound's, so the app with the better star average is not the one people write more warmly about.
SMS Spam Blocker ships an update every 23 months, IfFound every 8 months. The most recent releases landed on November 2, 2026 and November 6, 2026 respectively.
