User Reviews

Users largely report that Lux Light Meter Pro is unreliable and difficult to trust. The top issues are erratic and inaccurate readings, frequent bugs and unresponsiveness, and a subscription-driven pricing model viewed as bait-and-switch. Additional concerns include unclear units and interpretation of results, and limits on maximum measurements. A few note it can work in very simple scenarios or with workarounds, but the overall consensus is that reliability and value are poor in its current state.

Pros

Core function: provides light measurement (lux) for a target area, which is the app's primary purpose.
Reported use in simple scenarios (e.g., measuring apartment hallway lighting) for quick checks.
Some users indicate workarounds (e.g., back camera) can yield readings in certain cases.
Historically, the app has been used in educational contexts for basic lux measurements.

Cons

Highly unreliable and inconsistent readings: same light source yields widely different values across trials; initial spikes can skew averages.
Frequent bugs and poor reliability: app unresponsive, Help tab errors, readings not saving, and features not working as advertised.
Forced subscription model and perceived poor value: ongoing charges, poor trial experience, and reports of a nonexistent free version.
Unit and interpretation confusion: unclear when to use lux vs fc, with questions like whether FC values should be scaled (e.g., multiply by 100).
Readings capped or limited (e.g., max around 1741 lux) and poor calibration against professional meters; not dependable for high-intensity sources.

Recent reviews

In very dark situations (night time long exposure photography, for example) the meter stops measuring under what’s the equivalent of iso 400, f11, 8 seconds. In situations that require 60 second exposure for iso400, f11, it still gives 8 seconds. Could have been great, but unusable for my purpose because of this cap.

Why do lumens only show up as the values 2 → 55 → 94 → 145 → 214 … with the actual number flickering around /- 3 for each? Try this experiment: move the spot along a brightness gradient. Or change your computer monitor brightness. You'll never see a number /- 3 away from those values. Tested it on 3 different iPhones. So if error margins < 50 lumens are unacceptable to you, avoid.
