Yes! Looks like I found my replacement app. – RAW Power Review

I’ve been using an app from the biggest name in Photo editing and manipulation. It used to be better than it is now, but they’ve gutted it and made culling harder to do. Plus there was no way to batch edit. Enter RAW Power: It doesn’t make the culling process any quicker, but batch edits work (if slowly) and it brings some nice features to the table as well. First, it actually edits the raw photos in iOS Photos app. No more needing to export to use your edited images. Not only that, but the edits are non-destructive! I’m guessing the edits are metadata that is embedded in the raw photo, but they can easily be changed again after committing. Bonus: You’ll have one image instead of two (or more) to deal with. RAW Power also lets you manage your images, moving them between folders and albums. The changes are reflected in the photos app as well. I don’t see how to create folders within the app, so I’m doing that in Photos before moving back to RAW Power. Something else that sets it apart is the ability to apply edits to a batch of photos. This process is rather slow, but it beats pasting edits one by one. Get a bunch of files ready, set it to work, and go do something else for awhile. It’s slow, but it’s not tedious since you’re not sitting there doing the work repetitively. It’s far from perfect, but it’s miles ahead of other apps (including apps from the big guns in the industry). I’d love to see a better selection tool for batch work, and moving photos, something where the first tap toggles your beginning image and a second touch defines the other end of the sequence. As it is now you have to tap each photo individually. Even Photos’ tap and drag is better in this regard. Another option would be a filtered search and a “select all” for search results, but that wouldn’t work in every situation. I’d love it if the developers could let us add or edit metadata, including tags, especially if it was searchable, but I suppose that could be accomplished with albums (though it would look terrible) since “moving” a photo to a new album doesn’t remove it from any other albums it’s been added to. The transfers happen so quickly that I’m pretty sure the “new” photos are virtual copies, but I don’t know if you might end up messing up the database.
