How do I delete a friend?
From our iPhone app: go to the home screen and tap the name of the friend you want to delete. Next, on that friend's screen, tap on the settings icon in the top right corner (looks like a cog). That should bring you to the friend settings screen, with options to "Edit friend info" or "Delete this friend". (Note that you cannot edit friends who have already logged in – once an account is claimed, only the owner can update his or her name and email address.)
From our Android app: go to the home screen and tap the name of the friend you want to delete. Next, on that friend's screen, tap the "..." icon in the action bar and choose "Friend settings".
