# Ad Security Center vs iBlocker

The clearest difference is review sentiment: Ad Security Center at 73% against iBlocker's 25%. Ad Security Center also leads on update cadence (weekly vs every 5 weeks). iBlocker's advantage is rating (4.4 vs 3.9). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Ad Security Center sells 4 in-app purchases, starting at $4.99 per month and iBlocker sells 11 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

iBlocker holds the better App Store score, 4.4 against 3.9. Both are backed by a comparable volume of ratings — 445 and 733 respectively. Written reviews complicate that: 73% of Ad Security Center's written reviews are positive against 25% of iBlocker's, so the app with the better star average is not the one people write more warmly about.

Ad Security Center ships an update weekly, iBlocker every 5 weeks. The most recent releases landed on October 17, 2026 and October 15, 2026 respectively.
