# memoryOS vs Lobe

The clearest difference is ads: memoryOS at none against Lobe's shown. memoryOS also leads on ratings volume (17K vs 9) and chart position (#54 vs unranked). Lobe's advantage is update cadence (every 4 days vs every 2 weeks) and review sentiment (100% vs 80%). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. memoryOS sells 23 in-app purchases, starting at $3.99 per 7 days and Lobe sells 6 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for memoryOS against 4.9 for Lobe. That said, the two scores are not equally well evidenced: memoryOS has 17K ratings behind it against 9, so its average is the more settled of the two. Written reviews are what separate them: 80% of memoryOS's written reviews are positive against 100% of Lobe's.

memoryOS ships an update every 2 weeks, Lobe every 4 days. The most recent releases landed on October 28, 2026 and October 24, 2026 respectively.
