# b vs GVM LED

The clearest difference is update cadence: GVM LED at every 2 months against b's every 12 months. GVM LED also leads on device support (3 vs 1) and iOS requirement (13.0 vs 16.0). b's advantage is review sentiment (43% vs 22%) and ratings volume (24 vs 5). On price, rating, ads 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.

GVM LED holds the better App Store score, 3.2 against 3.0. Both are backed by a comparable volume of ratings — 24 and 5 respectively. Written reviews complicate that: 43% of b's written reviews are positive against 22% of GVM LED's, so the app with the better star average is not the one people write more warmly about.

b ships an update every 12 months, GVM LED every 2 months. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
