Verdict
The clearest difference is ads: Mathematical N at none against NBack 3D's shown. Mathematical N also leads on ratings volume (85 vs 1) and iOS requirement (13.0 vs 15.6). NBack 3D's advantage is rating (5.0 vs 4.7) and review sentiment (100% vs 81%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Mathematical N sells 1 one-off in-app purchase and NBack 3D sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
NBack 3D holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Mathematical N has 85 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 81% of Mathematical N's written reviews are positive against 100% of NBack 3D's.
Mathematical N ships an update every 8 months, NBack 3D every 10 months. The most recent releases landed on October 17, 2026 and October 3, 2026 respectively.
