ReceptionRating · Positive reviews · Number of ratings

ChargerSync(legacy) holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: Lux Light Meter Pro has 5.2K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 21% of Lux Light Meter Pro's written reviews are positive against 11% of ChargerSync(legacy)'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 11, 2026 and November 3, 2026 respectively.
