Invite-only for now
There is no public enrollment link yet. This page will not pretend otherwise.
What you will test
Add one real person, choose circle and closeness, write a dated memory, relaunch, search in list view, inspect the Connection state, and verify that a failed network path does not prevent local use.
What is not in this beta
A public invitation, App Store listing, iPad or web client, messaging, photos, reminder notifications, inferred closeness, paid plan, or checkout is not available.
