Flock, a new iPhone app from the people behind Bump, solves the first world problem of having to send photos to your friends through e-mail by creating shared photo albums with your friends with pictures that have similar metadata. It works like magic.
You know the situation, you're out with a bunch of friends and everyone's snapping photos with their iPhones and everyone wants each others pictures. What do you do? Ask them to e-mail it to you? Hope they remember? Be surprised on Facebook later? With Flock, you don't have to do anything, and you'll still get the pictures.
The way Flock works is you take photos with any iPhone camera app and then Flock sees who you're Facebook friends with and finds anyone with the same camera metadata (location, time) to automagically create a shared album with pictures you've all taken (you get an option to pick which pictures you share, of course). Your pictures, your friend's pictures, your other friend's pictures from that night out are all popped into one album without e-mailing or MMSing or doing any work. Flock just gently reminds you to share pictures.
Flock is better than other apps that do similar photo sharing things because Flock doesn't force you to use its own camera (it doesn't even have a camera in the app) and works with pictures you've taken before, in your camera roll. Basically, as long as your Facebook friends use Flock, you'll be able to easily share pictures with each other without ever e-mailing it to one another again. [iTunes via The Next Web]
