# RGB Lights vs U

The clearest difference is review sentiment: U at 100% against RGB Lights's 22%. U also leads on rating (3.7 vs 2.0) and update cadence (every 3 weeks vs every 4 months). RGB Lights's advantage is ratings volume (16 vs 3). 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.

U holds the better App Store score, 3.7 against 2.0. That said, the two scores are not equally well evidenced: RGB Lights has 16 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 22% of RGB Lights's written reviews are positive against 100% of U's.

RGB Lights ships an update every 4 months, U every 3 weeks. The most recent releases landed on October 3, 2026 and October 20, 2026 respectively.
