There are dozens of photo editing apps on the App Store, many of them free. But far too many of those free apps are lacking some of the basic functions that are needed for a photo editing app to be useful, or they have cluttered, hard-to-use interfaces. BeFunky Photo Editor has none of those issues, and combined with Facebook sharing, channels to view and share photos through the app, and much more, it is one of the better options on the App Store.
The BeFunky editor is a dual-purpose tool. The first role of the app is to connect you with other users and their photos. The focus is on content, not users, so you'll see a lot of photos, but you can also like and share images and if you dig deep enough into any one menu, you can follow individuals and the photos they share. Facebook integration means you don't need to use BeFunky's tools, nor do you need to register--or you can skip the social aspect altogether and just use the editor. The editor is very impressive, providing more than a dozen filters, rotation and cropping tools, and more to make your picture look just right. Combined with easy-to-use interface tools, quick load times, and easy sharing, this is a very powerful, and yet very easy-to-use tool.
If you are looking for a solid, well-designed, free photo editing tool that makes the social components optional, check out BeFunky Photo Editor. It is one of the best such tools currently on the App Store.
