This app uses the light sensor to measure illuminance in lumens per square meter (lx) or lumens per square foot (foot candles). FOR INDICATION ONLY. Results depend on your device and its hardware (Not every device has a light sensor and quality of the sensors varies massively). Features include:

Analogue dial to show current reading.
Maximum and minimum values.
lx or ft-c units.
4 time constant options. 3 Refresh speeds.
Graph – Shows the time depedence of the light.
Autoscale or manual (pinch & pan) Y-Axis.
Calibrate option – If you have a calibrated light meter or known light source, you can use this option to calibrate the meter. (However app is still for Indication Only).

More details can be found on the website.

User's Reivew

5 ★ Does what it says on the tin. Love the graphing and min/max function, since most of my use here is comparing two sources. We'll done! Saw this on AvE on YouTube, screenshotted it to get the bame. Wasn't disappointed! Free and no ads AND not junk is a rarity these days -- thank you for releasing this!by David Brady on November 05, 2016
3 ★ This app is not working properly on my HTC smartphone. This app sometimes indicates brightness, even when I cover the sensor. Likewise, it sometimes indicates darkness, even the sensor faces a light source. I'm just confused. Could somebody please tell how to calibrate the app? Thank you!by Pierre Alusta on December 28, 2015
5 ★ Brilliant for testing my lighting for camping or fishing. Lets me know when to swap out 12v batteries when running multiple lights from them. Well done to the Author its nothing short of excellent...thankyou!!by Skorpion Reaper on August 19, 2016
1 ★ It fluctuates between 0 and the actual measure randomly, have to keep your finger on the screen at all times in order to have a better Juan D Estrada on July 20, 2016
2 ★ Numbers drop to zero if light does not change for a few secinds. Impossible to get a stable Anonymous on January 15, 2016
2 ★ Him does not seen to work as expected or even at all meter swings back to zero and back againby Michael H on November 11, 2016
1 ★ Value drops to zero almost immediately when light value doesn't changeby Jon Rivers on January 23, 2016
3 ★ Works well but whats up with the pink??? The developer really needs to reconsider their color choice to something neutral or give the user control of it in settings. It would also be a nice to have the option to completely do away with the "Meter" look and have a full screen without the child-like Anonymous on November 19, 2017
2 ★ Compared a few light meter reading apps. Here are my findings: Light Reading Meter is best, light meter pro comes 2nd and lux meter Girish Dhoble on June 02, 2016

Questions & Answers

Q: What is an APK File?

A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.

Q: If I install an APK from this website, will I be able to update the app from the Play Store?

A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.

Q: Why can guarantee APK 100% safe?

A: Whenever someone wants to download an APK file from, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.

Q: What are Android App permissions?

A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
