On it’s basic settings, it takes 4 photos, a fraction of a second apart. It snaps action, as the name suggests. It does exactly what it says on the tin.
It’s got some excellent basic effects built in for taking photos – sepia, assorted LOMO effects – and a couple of different basic layouts. I love the standard, 4 tall, narrow pictures.
It’ll do square photos as well, 3×3 layouts, 2×3 layouts. Superb. The time delay between photos is configurable as well. It integrates into anything you’ve got for sharing things on your phone, as well as the http://steply.com/ service (which will, in addition, autopost to Twitter and Facebook). The only drawback I’ve found is there’s no way to save the photos direct to your phone. To achieve this, I share photos to Dropbox.com, an app I’ve also got installed.
Yes, there are adds on the photo preview screen, but they’re not obtrusive. Just ignore them.
This app fills a niche and fills it well. Enjoy.
