# Mathematical N vs N

The clearest difference is rating: Mathematical N at 4.7 against N's 4.0. Mathematical N also leads on review sentiment (81% vs 50%) and ratings volume (91 vs 2). N's advantage is update cadence (every 6 days vs every 8 months) and monetization model (free vs free with in-app purchases). On price, ads, 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 3 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Mathematical N holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Mathematical N has 91 ratings behind it against 2, 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 50% of N's.

Mathematical N ships an update every 8 months, N every 6 days. The most recent releases landed on November 6, 2026 and October 31, 2026 respectively.
