The old one stops working - No account, no email address KEEP YOUR CIRCLES APART - Travel friends, a club, family — you can be in several groups at once - Switch from the top of the screen. The colour around the edge tells you where you are - Your own private space has no colour, so you always know when nobody else is looking YOU DECIDE WHAT LEAVES YOUR PHONE - Choose where each memory goes - "Remove from the group" and "delete everywhere" are separate choices - Notifications are per group PLACES YOU WANT TO GO, TOGETHER - Share "want to go" pins with your group - Been there?
