# Mathematical N vs N

The clearest difference is ads: Mathematical N at none against N's shown. Mathematical N also leads on iOS requirement (13.0 vs 26.0). N's advantage is update cadence (every 4 days vs every 8 months). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Mathematical N 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.

Mathematical N ships an update every 8 months, N every 4 days. The most recent releases landed on September 6, 2026 and September 22, 2026 respectively.
