I never write reviews. But for this app I had to. It definitely deserves more attention. It's has an absolutely great interface. Much better than the stock photos app with iOS.
Not only does it look amazing but it has so many excellent uses. Batch tagging images is so useful. It will let you creat gifs with several images. It edits video right in the app (along with image editing built in as well)!
It can basically function as any photographers main app, letting them organize, compare and pick their best images, then tag and edit them, all within this one app!
If you need more advanced editing like layer masks, you will still need to use another app. However, given how great this app already is, I wouldn't be surprised if more advanced image editing gets added. Just yesterday, for example, they added noise reduction.
A big thanks to the developers from me! This was exactly what I was looking for as a photographer to organize, tag, and edit my images.
Ps. For only a few dollars for add ons inside the app, this is a great deal!
