Kaptur (Eye Candy)
If you've taken a group trip or attended an event with others and later wanted to aggregate all of the photos taken by your friends, Kaptur is worth checking out.
The app uses Facebook album titles, captions, and tags to assemble collections of pictures from specific events. When you click on photos, Kaptur uses an algorithm to search for similar images and then create an album that you can edit, turn into a music-infused slideshow, or share and transform into a photo book.
Kaptur is especially popular for wedding photo collections, because it lets newlyweds find and gather thousands of photos and videos posted online by their guests.
