Verdict
The clearest difference is rating: GVM LED at 3.2 against S's 2.7. S's advantage is review sentiment (36% vs 22%) and ratings volume (41 vs 5). On price, update cadence, 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 2.7. That said, the two scores are not equally well evidenced: S has 41 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 22% of GVM LED's written reviews are positive against 36% of S's, so the app with the better star average is not the one people write more warmly about.
GVM LED ships an update every 2 months, S every 6 weeks. Both last shipped on October 24, 2026.
