Two apps I recently discovered are Vintango and Prism.
Vintango, currently FREE on The App Store (normally priced at $2.99) offers a variety of vintage effects. It's an easy to use interface. What I like best about Vintango is the ability to preview your photo with all of the presets at a glance. Here are just a few from the Basic Presets. There are also 20 Classic Styles, 20 Black and White and 20 Lomo Styles.
You can also crop or rotate your image and add text using one of 29 font styles. From Vintango you can save your image or share to Instagram, Facebook or Twitter.
Prism (available on The App Store for $2.99) Prism has a different approach to filtering your image. Just watch the video below to check out the unique wheel navigation.
Prism has 14 color-based filter groups
128 professional filters
Supports high resolution images
Here are just three different edits I got in just a few seconds with Prism.
I'm not sure if either Vintango or Prism offer anything completely unique as far as photo results, but if you don't have a good filter app that you already like either of these would be worth adding to your app arsenal.
