# USB vs UC+

The clearest difference is rating: UC+ at 5.0 against USB's 2.0. USB's advantage is update cadence (every 5 weeks vs every 9 months) and ratings volume (29 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

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

UC+ holds the better App Store score, 5.0 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.

USB ships an update every 5 weeks, UC+ every 9 months. The most recent releases landed on September 22, 2026 and September 9, 2026 respectively.
