Verdict
The clearest difference is rating: Luxmeter at 4.4 against Temtop's 2.9. Luxmeter also leads on update cadence (every 5 days vs every 5 weeks) and ratings volume (257 vs 82). Temtop's advantage is in-app purchases (none vs 7) and ads (none vs shown). On price and device support there is nothing between them.

Luxmeter holds the better App Store score, 4.4 against 2.9. Both are backed by a comparable volume of ratings — 82 and 257 respectively. Written reviews complicate that: 32% of Temtop's written reviews are positive against 8% of Luxmeter's, so the app with the better star average is not the one people write more warmly about.
Temtop ships an update every 5 weeks, Luxmeter every 5 days. The most recent releases landed on November 4, 2026 and November 8, 2026 respectively.
