This app is awesome. The most useful mobile app ever, of course for me! I cultivate some plants. And it helped me to calculate the light intensity of my grow room. I dont need a lux meter (which is realy expensive in my country) anymore. And there's another cool thing in the app which enables you to record the data of the received light during a period of time. I'd really suggest you to download it.

Calibrated with an industrial meter. Calibration couldn't be easier. Enter your phones reading, enter the reference value and it automatically calculates the offset. Once calibrated it is remarkably accurate. Outstanding app. Thank you!

Be careful! This app wants permission to your files and is clearly tracking you and giving your data to other advertisers! The app said that my phone didn't have a sensor and I could clearly see a proximity sensor above my screen. Please stop collecting too much of our personal data just for influential ads and please fix the problem.
