Comments on Lux Light Meter for Android

★★★★★ Chandru Menghani · Mar 29, 2024

Very good and accurate. Rechecked with conventional lux meter. Good experience.

★★★★★ Bernard Waldron · Apr 25, 2020

This light meter works really good I can see how much my lights are putting out thank you for the app

★★★★☆ robert Lewin · Jul 24, 2022

Simple but effective I use it to measure the light transmission through various roller blind materials

★☆☆☆☆ HAL 9000 · Jul 25, 2024

Full videos unstoppable adds. I have no idea if the app works. Uninstalled immediately.

★★☆☆☆ Chris Duffy · Nov 3, 2020

Overshadowed by intrusive ads. Decent enough, but usability is greatly hampered by pop up and screen ads. You think this was a must-have one of a kind app with the deluge. Have to click out of what you think is the app to use and then the rotation at the top of the screen. Dare you go into menu, and they ask for coffee donations. Calibration is worthless, no reference or setup instructions. Hey what do. You expect for. Free?

★☆☆☆☆ Francis Laj · Oct 13, 2020

It doesn't work on Galaxy S10... always shows 1 lux !!!!
