RSVPing is a promise; a calendar entry is a plan. The Add to calendar button turns one into the other, and it works for no-account guests too.
Where the button is
| Where | When it shows | Options |
|---|---|---|
| The event page | Always, in the event details | Google Calendar, Outlook |
| Your invite page (from a text or email invite) | Once you've said you're going | Google Calendar, Outlook, Apple / .ics |
| A share link (/join) | On the confirmation screen after you RSVP going | Google Calendar, Outlook, Apple / .ics |
| Your RSVP confirmation email | When you're going | Add to calendar (.ics) |
Adding it
Tap Add to calendar
A small menu drops down with the calendar options.
Pick your calendar
Google Calendar and Outlook open a pre-filled new-event screen in that calendar, just hit save there. Apple / .ics downloads a calendar file that opens in Apple Calendar, or any calendar app that takes .ics files (which is all of them).
What lands in the entry
The event name, start and end time, the location (venue name and address), and the event description. No end time set? Google and Outlook block out two hours, which covers most parties and undersells the good ones. The .ics file also carries a link back to the event page and the host's name as the organiser.
The calendar entry doesn't sync. If the host moves the event, your calendar won't know, PopIn will tell you (that's what invite notifications are for), and you can add the new time the same way. Your invite link always shows the current details.
The invite-page and email versions work without a PopIn account, they're keyed to your personal invite link. RSVP going, add it to your calendar, show up. That's the whole job. See RSVPing without a PopIn account.
Plans change? Changing your RSVP covers the graceful exit, just remember to delete the calendar entry yourself.
