This ingenious little device turns any smartphone into an accurate mobile light meter. All you do is clip it onto your device’s front facing camera and use it with any of a number of light meter apps such as the free Luxi app. Just like that you have a simple light meter with you at all times, but one that offers far more accuracy and reliability than using your phone’s camera on its own. And the Luxi for All is designed to work with any smartphone or tablet without damaging the screen, so it will work beautifully with whatever device you own.
