# Iron Blocker vs Security Master

The clearest difference is rating: Security Master at 4.4 against Iron Blocker's 3.0. Security Master also leads on ratings volume (4K vs 4) and update cadence (every 11 days vs every 5 weeks). Iron Blocker's advantage is ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Iron Blocker sells 3 in-app purchases, starting at $9.99 per 7 days and Security Master sells 2 in-app purchases, starting at $8.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Security Master holds the better App Store score, 4.4 against 3.0. That said, the two scores are not equally well evidenced: Security Master has 4K ratings behind it against 4, so its average is the more settled of the two.

Iron Blocker ships an update every 5 weeks, Security Master every 11 days. The most recent releases landed on November 4, 2026 and November 8, 2026 respectively.
