# Sophia vs Memory

The clearest difference is ads: Sophia at none against Memory's shown. Memory's advantage is iOS requirement (16.0 vs 18.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Sophia sells 10 in-app purchases, starting at $5.99 per 7 days and Memory sells 6 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
