Afterlight is one amazing photo editing app! It has plenty of filters, even three categories, and of course, you can adjust every filter. Afterlight has got film effects too. The interface itself is very beautiful and uncluttered. Afterlight includes a huge library of frames, some of them are basic, you even have different shapes, letters and numbers! Overall. I think Afterlight makes photo much prettier.
