# OtoScope vs USB

The clearest difference is rating: OtoScope at 2.3 against USB's 2.0. OtoScope also leads on iOS requirement (8.0 vs 13.0). USB's advantage is ratings volume (29 vs 8). On price, review sentiment, update cadence and ads there is nothing between them.

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

OtoScope holds the better App Store score, 2.3 against 2.0. Both are backed by a comparable volume of ratings — 8 and 29 respectively. Written reviews complicate that: 14% of OtoScope's written reviews are positive against 18% of USB's, so the app with the better star average is not the one people write more warmly about.

OtoScope ships an update monthly, USB every 5 weeks. The most recent releases landed on October 22, 2026 and October 15, 2026 respectively.
