I use QuickShot at least once a week, and usually once a day (previous review. QuickShot is a simple camera app that doesn't have a bunch of effects or photo tricks. It simply snaps a shot and uploads it to a specific Dropbox folder with a predefined file name. Camera profiles are used to preconfigure the Dropbox receiving folder and the file name format.
The latest update adds a URL scheme for use with apps like LaunchCenter. Use "quickshot://camera/profileName" to open QuickShot into a specific profile ready to take a shot and upload. This is a small but meaningful update.
