# N'Back vs N

The clearest difference is update cadence: N at every 4 days against N'Back's every 9 months. N'Back's advantage is iOS requirement (16.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. N'Back sells 1 one-off in-app purchase and N sells 1 in-app purchase, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

N'Back ships an update every 9 months, N every 4 days. The most recent releases landed on September 11, 2026 and September 7, 2026 respectively.
