GuestReel provides couples with the ideal tool to record a 'guest's-eye' view of their wedding day. It also provides an entertaining addition to the 'big day' where everyone can share wonderful photos and memories. Guests download the app and login with a password for the wedding they are attending (This will usually be distributed by the bride and groom in advance) and then use it to snap photos throughout the day.There are several image filters to vary the style of photos taken and users can add messages/captions to personalise them.

Users who have signed in to the same wedding can see the collective pool of photos and associated messages in the Guest Reel gallery. Images can also be shared via Facebook.
