If you are using another playback method, you’ll have to press play manually at 4:30:00. Make sure your phone clock or your watch is synced to atomic time so you know exactly when to press play. Group with others if you don’t know the right time.

What if I get to the event late?

Start listening at the start time, and you’ll get there when you get there. Be careful crossing streets, etc.

What if I don’t press play at exactly the right time?

If you can tell you are significantly off, ask to look at a neighbor’s device and try to sync back up to the correct time. You’ll have more fun if you’re more in sync. Those using the app should automatically be in sync with atomic time.

Do I have to RSVP?
