This is the best app for organizing and viewing photos. Not only does it have a beautiful interface, it also lets users sort their photos - something thats impossible with the stock photos app in iOS.
The only minor downside is that photos are compressed so the quality loses a little. Furthermore importing photos from Dropbox would be great. I hope this comes in a future version.
