# AdZero vs PubBlock

The clearest difference is in-app purchases: AdZero at none against PubBlock's 1. AdZero also leads on iOS requirement (14.0 vs 17.6). PubBlock's advantage is update cadence (every 2 weeks vs every 2 months). On price, ads and device support there is nothing between them.

Both are free to download. PubBlock sells 1 one-off in-app purchase. AdZero asks for nothing beyond the download.

AdZero ships an update every 2 months, PubBlock every 2 weeks. The most recent releases landed on October 24, 2026 and October 26, 2026 respectively.
