# AdBlocker Ultimate vs iShield

The clearest difference is review sentiment: iShield at 93% against AdBlocker Ultimate's 28%. iShield also leads on update cadence (every 5 weeks vs every 61 months) and iOS requirement (14.1 vs 16.0). AdBlocker Ultimate's advantage is rating (4.0 vs 3.2) and monetization model (free vs free with in-app purchases). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. AdBlocker Ultimate sells 1 in-app purchase, starting at $9.99 per year and iShield sells 3 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

AdBlocker Ultimate holds the better App Store score, 4.0 against 3.2. Both are backed by a comparable volume of ratings — 8 and 15 respectively. Written reviews complicate that: 28% of AdBlocker Ultimate's written reviews are positive against 93% of iShield's, so the app with the better star average is not the one people write more warmly about.

AdBlocker Ultimate ships an update every 61 months, iShield every 5 weeks. The most recent releases landed on August 14, 2026 and September 14, 2026 respectively.
