I don’t much go for distressed filters these days, but I quite like Distressed FX.
Distressed FX offers 19 color/treatment filters (plus Birds!) and 17 scratch layers (plus the ability to create custom scratch designs), and the ability to tune the intensity of the filters.
It’s also possible to make simple tweaks to color, brightness, and contrast.
It saves images to a maximum dimension of 2048 (2048×2048 for square images; 2048×1536 for 4×3 images from the iPhone camera), and this is plenty for social media.
