When used as a quick contrast, brightness, contrast, etc. and sharpening tool, Snapseed works about as well as iPhoto or any of a large number of simple image tools you'll find on the web. The magic is supposed to happen with the filters. They have names like "Grunge" and "Drama" and "Vintage" and "Tilt and Shift." They do most of the trendy stuff you'll see on the web. I gave it a spin this evening. While it's fun and makes stuff look different it's canned so eventually the effects will get old. That shouldn't keep you from having fun. Afterall, it's only $20.
I'll run the effects by the art directors who deserve them.
But once you've found a cute model. Found a cute dress. Gotten her on the floor with her legs in the air, you've really done all the hard work. Why give a boxed software effect all the credit?
I'll keep it. But like cheap alcohol I'll use it sparingly.
