# USB Sharp vs i

The clearest difference is rating: i at 4.0 against USB Sharp's 3.1. i also leads on in-app purchases (none vs 6) and ads (none vs shown). USB Sharp's advantage is review sentiment (53% vs 18%) and ratings volume (18 vs 2). On price, update cadence and device support there is nothing between them.

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

i holds the better App Store score, 4.0 against 3.1. That said, the two scores are not equally well evidenced: USB Sharp has 18 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 53% of USB Sharp's written reviews are positive against 18% of i's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 21, 2026 and September 18, 2026 respectively.
