After you create an account, you can add the family members or friends that you would like to have access to your memory timeline.
Then you will see a question prompt from the app (i.e. what's your favorite childhood memory? who was your first love? what's your favorite comfort food?), daily, weekly, or monthly...and when the question comes up on your screen you can tap record and it pulls up your phone camera so that you can create a video response to the question.
This video, or "memory" then gets placed in your timeline, and your family/friends get alerted that you dropped a new memory in the timeline to view. There's also an option to share it to facebook.
All your memories from your loved ones now in one place.
