A sealed envelope that opens on tap, with countdown, venue map, RSVP and a guest book saved to Google Sheets.
Sealed envelope with wax seal: tap to open
1 / 8What it does
A sealed envelope that opens on tap, a countdown to the ceremony, venue map, RSVP and guest book saved straight to Google Sheets, and one-tap add-to-calendar. It is a reusable template: names, date and venue change in one place.
Guests tap the wax seal, the envelope opens and the invitation slides out. The shortcut bar only appears after opening.
The event date carries the venue's timezone, so a guest overseas sees the correct countdown and calendar reminder.
Attendance and pax go straight to a Google Sheet via Apps Script. Guests can update their pax or cancel later.
Wishes appear on the card: three shown, the rest behind a tap. Duplicates are caught before they're saved.
Add to Google / Apple calendar, and a contact popup with the family's phone numbers.
Names, date, venue and swatches are marked EDIT in one file. Bride and groom photos appear automatically when dropped in.
