LightBox displays a resizable rectangle, from a small box to full screen. You can resize and reposition the box, set the colour and brightness. Touch the middle of the box and drag it to reposition and touch and drag any one of the box corners to resize. There are tools to display a grid, reset the box, choose between full screen or smaller box and lock the screen to prevent accidental changes when moving or touching your device.

You can view photographic transparencies, negatives or X-ray prints with a matched light source without the surrounding glare from a fully lit screen. Of course, if you prefer the full screen you can use that as well. Use LightBox as an inspection light, reading light, night light, light table, photography back light, a signal and … whatever else you can think of!

There is also a message banner scroller that cycles a short message across the screen; you can change the message, text size, colour, scrolling speed and direction.
