# ASC vs UNOi 4

The clearest difference is rating: UNOi 4 at 3.0 against ASC's 1.5. UNOi 4 also leads on review sentiment (50% vs 17%). ASC's advantage is update cadence (every 10 days vs every 6 weeks) and ratings volume (11 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

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

UNOi 4 holds the better App Store score, 3.0 against 1.5. That said, the two scores are not equally well evidenced: ASC has 11 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 17% of ASC's written reviews are positive against 50% of UNOi 4's.

ASC ships an update every 10 days, UNOi 4 every 6 weeks. The most recent releases landed on September 8, 2026 and June 1, 2026 respectively.
