# memoryOS vs CharmXP

The clearest difference is review sentiment: memoryOS at 80% against CharmXP's 46%. memoryOS also leads on rating (4.9 vs 4.4) and chart position (#55 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. memoryOS sells 23 in-app purchases, starting at $3.99 per 7 days and CharmXP sells 14 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.
