# Dual N vs Memory Athlete

The clearest difference is review sentiment: Memory Athlete at 100% against Dual N's 51%. Memory Athlete also leads on ads (none vs shown). Dual N's advantage is ratings volume (376 vs 3) and rating (4.6 vs 4.3). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Dual N sells 2 in-app purchases, starting at $0.99 per month and Memory Athlete sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Dual N holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Dual N has 376 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 51% of Dual N's written reviews are positive against 100% of Memory Athlete's, so the app with the better star average is not the one people write more warmly about.

Dual N ships an update fortnightly, Memory Athlete weekly. The most recent releases landed on October 27, 2026 and October 22, 2026 respectively.
