# Lux Light Meter Pro vs ChargerSync(legacy)

The clearest difference is rating: ChargerSync(legacy) at 5.0 against Lux Light Meter Pro's 3.9. ChargerSync(legacy) also leads on in-app purchases (none vs 4) and ads (none vs shown). Lux Light Meter Pro's advantage is ratings volume (5.2K vs 2) and review sentiment (21% vs 11%). On price, update cadence and device support there is nothing between them.

Both are free to download. Lux Light Meter Pro sells 3 in-app purchases, starting at $1.99 per month. ChargerSync(legacy) asks for nothing beyond the download.

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.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on November 11, 2026 and November 3, 2026 respectively.
