# S vs USB Camera

The clearest difference is ads: S at none against USB Camera's shown. S also leads on rating (3.0 vs 2.7) and monetization model (free vs ad-supported). USB Camera's advantage is update cadence (fortnightly vs monthly) and ratings volume (10 vs 2). On price and in-app purchases there is nothing between them.

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

S holds the better App Store score, 3.0 against 2.7. That said, the two scores are not equally well evidenced: USB Camera has 10 ratings behind it against 2, so its average is the more settled of the two.

S ships an update monthly, USB Camera fortnightly. The most recent releases landed on September 19, 2026 and September 25, 2026 respectively.
