# onsA440 vs n

The clearest difference is rating: n at 4.7 against onsA440's 2.0. n also leads on update cadence (every 2 weeks vs every 5 months) and ratings volume (3.2K vs 4). onsA440's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, review sentiment, device support and iOS requirement there is nothing between them.

Both are free to download. n sells 1 one-off in-app purchase. onsA440 asks for nothing beyond the download.

n holds the better App Store score, 4.7 against 2.0. That said, the two scores are not equally well evidenced: n has 3.2K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 73% of onsA440's written reviews are positive against 78% of n's.

onsA440 ships an update every 5 months, n every 2 weeks. Both last shipped on October 21, 2026.
