A Photo App with a Collaborative Twist

Comet is a trendy photo app that lets you make and share picture albums with family and friends. Available on both Android and iOS, the app lets you collate pictures of your friends from their cameras. To make this work, people you want to collaborate on the album should install the app. You can invite your family members and friends with a text message or email. Upon installation, people can start adding photos and the app would automatically download all the pictures.
