Carousel is a new app by the folks at Dropbox that make photo organisation and sharing really easy. When you upload your photos to the app and share with your friends, they get your photos and you get theirs.
With Carousel, you can organise all the photos you snap and they're automatically organised in a timeline of your life. Images are synchronised with Dropbox, and you can easily share one or an entire collection with friends and family -- without having to share them with the world. When you share, your photos are added to the carousel of others. The same goes when they share photos with you, allowing you and all the people in your life to build a collection of memories collaboratively.
Carousel is available for iOS and Android today.
