# n vs N

The clearest difference is rating: N at 4.0 against n's 3.0. N also leads on ads (none vs shown) and update cadence (every 6 days vs every 12 months). n's advantage is in-app purchases (none vs 3) and ratings volume (44 vs 2). On price and device support there is nothing between them.

Both are free to download. N sells 3 in-app purchases, starting at $1.99 per 7 days. n asks for nothing beyond the download.

N holds the better App Store score, 4.0 against 3.0. That said, the two scores are not equally well evidenced: n has 44 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 39% of n's written reviews are positive against 50% of N's.

n ships an update every 12 months, N every 6 days. The most recent releases landed on October 23, 2026 and October 18, 2026 respectively.
