# 1Blocker vs Kompress

The clearest difference is in-app purchases: Kompress at none against 1Blocker's 7. Kompress also leads on review sentiment (91% vs 64%) and rating (4.7 vs 4.5). 1Blocker's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 10 months). On price and device support there is nothing between them.

Both are free to download. 1Blocker sells 7 in-app purchases, starting at $2.99 per month. Kompress asks for nothing beyond the download.

Kompress holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: 1Blocker has 13K ratings behind it against 170, so its average is the more settled of the two. Written reviews point the same way: 64% of 1Blocker's written reviews are positive against 91% of Kompress's.

1Blocker ships an update every 2 weeks, Kompress every 10 months. The most recent releases landed on October 31, 2026 and October 25, 2026 respectively.
