# Scan vs Lux Light Meter & Photometer

The clearest difference is monetization model: Lux Light Meter & Photometer at free with in-app purchases against Scan's subscription. Lux Light Meter & Photometer also leads on rating (4.8 vs 4.5). Scan's advantage is ads (none vs shown) and update cadence (every 5 days vs monthly). On price, ratings volume, in-app purchases and device support there is nothing between them.

Both are free to download. Scan sells 7 in-app purchases, starting at $6.99 per 7 days and Lux Light Meter & Photometer sells 6 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Lux Light Meter & Photometer holds the better App Store score, 4.8 against 4.5. Both are backed by a comparable volume of ratings — 243 and 198 respectively. Written reviews complicate that: 100% of Scan's written reviews are positive against 85% of Lux Light Meter & Photometer's, so the app with the better star average is not the one people write more warmly about.

Scan ships an update every 5 days, Lux Light Meter & Photometer monthly. Both last shipped on October 27, 2026.
