# memoryOS vs The Supplement App

The clearest difference is in-app purchases: The Supplement App at none against memoryOS's 28. The Supplement App also leads on review sentiment (100% vs 80%). memoryOS's advantage is update cadence (every 2 weeks vs every 7 months) and ratings volume (17K vs 11). On price, rating, ads and device support there is nothing between them.

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

On the App Store both sit at effectively the same score — 4.9 for memoryOS against 4.8 for The Supplement App. That said, the two scores are not equally well evidenced: memoryOS has 17K ratings behind it against 11, so its average is the more settled of the two.
