# USB vs TCam Viewer

The clearest difference is review sentiment: TCam Viewer at 100% against USB's 18%. TCam Viewer also leads on rating (4.0 vs 2.0) and update cadence (fortnightly vs every 5 weeks). USB's advantage is in-app purchases (none vs 3) and ratings volume (29 vs 1). On price and ads there is nothing between them.

Both are free to download. TCam Viewer sells 3 in-app purchases, starting at $1.99 per month. USB asks for nothing beyond the download.

TCam Viewer holds the better App Store score, 4.0 against 2.0. That said, the two scores are not equally well evidenced: USB has 29 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 18% of USB's written reviews are positive against 100% of TCam Viewer's.

USB ships an update every 5 weeks, TCam Viewer fortnightly. The most recent releases landed on October 15, 2026 and October 7, 2026 respectively.
