# 67 vs BlockRot

The clearest difference is in-app purchases: 67 at none against BlockRot's 10. 67 also leads on review sentiment (85% vs 62%). BlockRot's advantage is update cadence (daily vs monthly) and rating (4.7 vs 4.4). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. BlockRot sells 10 in-app purchases, starting at $7.99 per 7 days. 67 asks for nothing beyond the download.

BlockRot holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: BlockRot has 505 ratings behind it against 73, so its average is the more settled of the two. Written reviews complicate that: 85% of 67's written reviews are positive against 62% of BlockRot's, so the app with the better star average is not the one people write more warmly about.

67 ships an update monthly, BlockRot daily. Both last shipped on October 24, 2026.
