Merrily Party Invitation & RSVP App

Overview

Merrily is a complete party invitation app. A host makes an invite that looks like a poster, shares one link, and sees who is coming, who brings what and every photo after the night. Guests reply in a tap, in the app or from the link on the web, and nobody outside the invite can find the event.

Key features

• Events: your next get-together as a poster card, and every invite waiting for your reply answered in place

  

• The invite: poster, when and where, who's coming, the host's updates, comments, the bring list and the album

  

• Create: pick a photo or type poster, write the invite (or let AI draft it), set plus-ones, capacity and questions

  

• Guests: replies, plus-ones, notes and answers for the host, and a nudge for the people who haven't replied

  

• Bring list: guests claim items one at a time, the host adds and edits them

  

• Album: everyone who went adds photos to one place

  

Screens

35 screens: welcome, sign-in with an email code, your profile, Events, the invite as guest and host, the reply sheet, guests, bring list, updates and comments, message guests, find a date and offer dates, album and photo viewer, the pass, check-in, edit, share, the four steps of making an invite, the link landing page, Activity, Memories, You, reminders, blocked people, Merrily Pro, terms, privacy and about. Light and dark.

AI and backend

Live mode runs on Supabase: one migration with row level security on every table and server functions for the rules that matter (the address hidden until a reply, capacity and the waitlist, plus-one limits, one claim per item, check-in by pass code, reset links, deleting a person's data). Photos and posters live in private storage buckets. Four AI tasks run in one Edge Function with Gemini: write the invite, draft an update, suggest a bring list, and make a poster from a few words. A second function deletes an account on request.

Monetisation

Merrily Pro is a subscription through RevenueCat (monthly and yearly). Free hosts get three upcoming events and 40 guests each; Pro adds AI posters, questions for guests, check-in at the door and up to 300 guests. A price at the door is shown to guests and paid at the venue, not processed in the app.

Setup

The app opens on sample events with no setup. To go live, connect Supabase and run the migrations, deploy the two Edge Functions with your AI key, add your RevenueCat keys, and publish the web app so invite links open for guests without the app. The README walks through each step.
