Do not read the “waste of money” or “can’t rotate, what a waste” reviews. You can do all of this, they just don’t know how to read. This app works great and is a solid way to add lightsaber effects to your photos. You can rotate, scale, change color, and unlike many, mask the saber effects so they properly disappear behind objects. Here are the down sides. If your saber glow goes outside the bounding box, you can not mask it off. Also, when viewed close up, the masking is a bit jagged and not very smooth. But in facebook (where most of us use these things) no one will notice. The controls are a little clunky to use. Having to hold down on the saber each time you want to change functions (rotate, scale, mask, color etc...) is cumbersome and it might be a better idea to just have those things in a simple drop down menu on the side that can always be accessed either with a quick tap, or just always visible. Other than those rather minor problems, it works quite well.
