I use this app quite a bit because the interface suits me. It’s easy to select editing features with the left semi-transparent palettes rather than continuously swiping to access a hidden left menu. I also like the effects and masks available. There are a few shortcomings as noted by other reviewers but I still go to this app first for editing needs. My biggest wish would be for an extension that would allow me to open Filterstorm from the Photos library.
