My little brother told my wife and I about a new app called
Capsule Cam. They have it for both Android and iPhone. Instead of putting disposable cameras out at the reception we had everyone at the wedding download the app.
Anytime someone snapped a picture with the app, the picture automatically uploaded to our digital wedding album. It worked like a charm and saved us a ton of time and money.
Even my Dad figured it out so I highly recommend.
