# USB Sharp vs U

The clearest difference is in-app purchases: U at none against USB Sharp's 6. U also leads on ads (none vs shown) and iOS requirement (9.0 vs 13.0). USB Sharp's advantage is review sentiment (53% vs 24%). On price, rating, ratings volume and update cadence there is nothing between them.

Both are free to download. USB Sharp sells 6 one-off in-app purchases. U asks for nothing beyond the download.

U holds the better App Store score, 3.3 against 3.1. Both are backed by a comparable volume of ratings — 18 and 19 respectively. Written reviews complicate that: 53% of USB Sharp's written reviews are positive against 24% of U's, so the app with the better star average is not the one people write more warmly about.

USB Sharp ships an update every 3 weeks, U every 5 weeks. The most recent releases landed on September 21, 2026 and September 18, 2026 respectively.
