Features & Capabilities

Light Meter is a Chrome extension that utilizes your device's built-in light sensor to measure illuminance, displayed in lumens per square meter (lx) or lumens per square foot (foot candles). Designed for indication purposes, the extension showcases current light levels through an analogue dial, along with statistical features like averaging, maximum, and minimum values.

Additional functionalities include selectable units (lx or ft-c), multiple time constants, refresh speeds, and a graphical display showing the time dependence of light intensity. Users can autoscale or manually adjust the Y-Axis for better visualization, and calibrate the meter using a known light source or calibrated light meter to improve accuracy. Note that measurement accuracy depends on the device hardware and sensor quality. Find more details and support on the official website.

User Reviews

Users generally find the Light Meter app accurate and reliable within a mid-range light spectrum, appreciating its ad-free or minimal ad environment, simple interface, and real-time measurement features. However, multiple reviews note issues with fluctuating or inaccurate readings in low or very bright light, alongside concerns over ads, privacy, and user interface aesthetics. Accessibility limitations and calibration difficulties are also mentioned as areas needing improvement.

Pros

Accurate light measurement in mid-range light conditions comparable to commercial meters.
Free app with no ads or minimal ads, providing good value to users.
Simple and user-friendly interface with useful features like min/max values and graphing.
Reliable for relative light measurements and useful in practical scenarios like camping or battery testing.
Real-time light measurement capability, distinguishing it from other apps.

Cons

Inaccuracy or fluctuation in readings in very low or very bright light conditions.
Presence of ads and potential privacy concerns in newer versions, disappointing some users.
Issues with app readings fluctuating or dropping to zero even when light conditions are stable.
User interface color choices (e.g., pink theme) are disliked by some users and lack customization.
Accessibility issues for blind users and no apparent calibration options causing confusion.

Recent reviews

I've compared this particular app to my commercial light meter and it reads exactly the same in the mid range. Once you start getting dimly lit or very bright situations variance starts to become noticeable which I imagine has everything to do with the limits of my sensor. However, for relative measurements and light between 50 and 1500 lm I would call this app 100% reliable. Thank you so much! Sometimes I feel like you're making these things just for me.
