Verdict

The call

The clearest difference is in-app purchases: Skool Loop at none against memoryOS's 28. Skool Loop also leads on review sentiment (92% vs 80%). memoryOS's advantage is ads (none vs shown) and ratings volume (17K vs 43). On price, update cadence, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

memoryOS holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: memoryOS has 17K ratings behind it against 43, so its average is the more settled of the two. Written reviews complicate that: 92% of Skool Loop'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.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on October 24, 2026 and November 3, 2026 respectively.
