Verdict

The call

The clearest difference is ads: memoryOS at none against Lumosity's shown. memoryOS also leads on rating (4.9 vs 4.7). Lumosity's advantage is update cadence (weekly vs every 2 weeks) and ratings volume (131K vs 17K). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Lumosity sells 8 in-app purchases, starting at $11.99 per month and memoryOS sells 23 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
