ReceptionRating · Positive reviews · Number of ratings

Lux Light Meter Pro holds the better App Store score, 3.9 against 2.7. That said, the two scores are not equally well evidenced: Lux Light Meter Pro has 5.2K ratings behind it against 406, so its average is the more settled of the two. Written reviews complicate that: 42% of Dimmer's written reviews are positive against 21% of Lux Light Meter Pro's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on November 1, 2026 and October 29, 2026 respectively.
