It's a good one. – Luminance Review

I really like this app, however, there is one thing that I find really find irritating, and that is when you are scrolling through the filters, you have to be very, very, very careful to touch I between the filters as to not add an unwanted filter to your selected photo. I spend more time backing out filters I didn't want than I do actually using the app. Aside from that, it's quality.
