Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Spektrum+ Smart Lighting holds the better App Store score, 4.3 against 3.0. That said, the two scores are not equally well evidenced: Spektrum+ Smart Lighting has 32 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of U's written reviews are positive against 0% of Spektrum+ Smart Lighting's, so the app with the better star average is not the one people write more warmly about.
U ships an update every 2 months, Spektrum+ Smart Lighting every 16 months. The most recent releases landed on June 1, 2026 and July 28, 2026 respectively.
