Ratings and reviews

Perfect app. It doesn't do anything except display a white screen. Other apps have messed it up trying to get fancy. I use it to measure the stabilizer in my pool, where it provides the backlight necessary to measure the turbidity of the water once a reagent is added. Sometimes I also use it to study tiny insects and other objects where a backlight helps. Just perfect.

Does exactly what it says on the tin with no frills. Turns your phone into a glorified lightbox. This is perfect for looking at photo negatives or transparencies. Just be sure to turn off Adaptive Brightness when using it to get full power. The lack of ads is the cherry on top of this cake of an app.

I like to take night portraits but don't like flashes as I prefer natural light (gives more context) and I have a sensitive camera. This app bumps up the light a little bit, to get a bit more out of the shadows. It also helps the AF more than a flash gun. I always have my phone with me, now it can act like a flash. It's easy to dim it, use screen brightness. Use torch simultaneously as bounce flash. Not as powerful as a real flash though.
