# Nothing X vs S&O

The clearest difference is rating: Nothing X at 4.7 against S&O's 3.0. Nothing X also leads on review sentiment (72% vs 33%) and ratings volume (3.4K vs 2). S&O's advantage is in-app purchases (none vs 3) and iOS requirement (12.0 vs 15.0). On price, update cadence, ads and monetization model there is nothing between them.

Both are free to download. Nothing X sells 3 one-off in-app purchases. S&O asks for nothing beyond the download.
