# my NOS vs DUApp

The clearest difference is rating: my NOS at 4.2 against DUApp's 1.8. my NOS also leads on ratings volume (283 vs 4) and review sentiment (13% vs 0%). DUApp's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

my NOS holds the better App Store score, 4.2 against 1.8. That said, the two scores are not equally well evidenced: my NOS has 283 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 13% of my NOS's written reviews are positive against 0% of DUApp's.

my NOS ships an update every 3 months, DUApp every 6 months. The most recent releases landed on October 18, 2026 and October 10, 2026 respectively.
