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.

there was a update that lets you adjust the brightness by swiping. this has completely changed how I use the app. I paint on clear plastic sheets and overlay that plastic on top of my phone so I can get a good line of sight. now that it's no longer just a "white screen" it changes its brightness whenever I use my markers. this ruins the app for me. completely.

What’s new

• Simplified Experience: Removed the swipe-to-adjust brightness feature based on customer feedback to return to a cleaner, more minimalist interface.
