# USB vs Uni Lab

The clearest difference is iOS requirement: Uni Lab at 11.0 against USB's 13.0. On price, rating, review sentiment and ratings volume there is nothing between them.

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

USB holds the better App Store score, 2.0 against 1.8. Both are backed by a comparable volume of ratings — 29 and 16 respectively. Written reviews complicate that: 18% of USB's written reviews are positive against 22% of Uni Lab'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 5 weeks. The most recent releases landed on September 22, 2026 and September 15, 2026 respectively.
