To invite people to your Album, open it and tap on "Share" button on the top right of side of your screen. If your friend(s) have Capture on their phone and when you share photos through text message, they will be taken directly to the App and where they can start adding photos or comment on existing photos. As people join your Album, you’ll see how many friends have added or commented on the photos. You can also choose between whether your friends can add photos or comment on your Album.
Open desired “Album” from Capture App and tap on three parallel dots located on the top right side for options and select “Share Album”
