# Lux Light Meter Pro vs Vsensor

The clearest difference is rating: Lux Light Meter Pro at 3.9 against Vsensor's 3.0. Lux Light Meter Pro also leads on ratings volume (5.1K vs 8). Vsensor's advantage is review sentiment (60% vs 21%) and in-app purchases (none vs 4). On price, device support and iOS requirement 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. Vsensor asks for nothing beyond the download.

Lux Light Meter Pro holds the better App Store score, 3.9 against 3.0. That said, the two scores are not equally well evidenced: Lux Light Meter Pro has 5.1K ratings behind it against 8, 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 60% of Vsensor's, so the app with the better star average is not the one people write more warmly about.

Lux Light Meter Pro ships an update every 3 months, Vsensor every 3 weeks. The most recent releases landed on September 24, 2026 and August 18, 2026 respectively.
