# Block Logic vs memoryOS

The clearest difference is rating: memoryOS at 4.9 against Block Logic's 4.4. memoryOS also leads on ads (none vs shown) and update cadence (every 2 weeks vs every 19 months). Block Logic's advantage is in-app purchases (none vs 28). On price, review sentiment, device support and iOS requirement there is nothing between them.

Both are free to download. memoryOS sells 23 in-app purchases, starting at $3.99 per 7 days. Block Logic asks for nothing beyond the download.

memoryOS holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: memoryOS has 17K ratings behind it against 55, so its average is the more settled of the two. Written reviews complicate that: 86% of Block Logic's written reviews are positive against 80% of memoryOS's, so the app with the better star average is not the one people write more warmly about.

Block Logic ships an update every 19 months, memoryOS every 2 weeks. The most recent releases landed on October 14, 2026 and October 19, 2026 respectively.
