How do guests RSVP without installing the app?

A shareable web RSVP link is the standard pattern — guests respond in the browser, organizers see it in the app. Prompt for it explicitly.

Which event niche retains users?

Recurring organizers: community groups, youth sports, religious organizations. One-time-event users (weddings) churn by design — price them one-time.

How to Build an Event Planning App with AI (2026)

What a event planning app needs

Guest list with RSVP tracking
Task checklist with deadlines
Budget tracker per category
Day-of timeline/schedule
Share view with co-organizers

The screens

Screen	What it does
Event Home	Countdown, progress across guests/tasks/budget
Guests	List with RSVP states, +1s, meals
Tasks	Checklist grouped by month-before
Budget	Planned vs actual by category
Timeline	Day-of schedule

The data model

Event: name, date, type
Guest: eventId, name, rsvpStatus, plusOnes
Task: eventId, title, dueDate, done
BudgetItem: eventId, category, planned, actual

The build prompt (copy this)

Paste this into ShipNative and it becomes a working React Native app with these screens, navigable in a live preview, in about two minutes:

“An event planning app for community organizers. Events with guest lists (RSVP tracking), task checklists with deadlines, budget planned-vs-actual, day-of timeline, shared access for co-organizers. Screens: Event Home with countdown, Guests, Tasks, Budget, Timeline. Free for 1 event, subscription for unlimited.”

Then iterate with small, screen-specific prompts (“make the primary button bigger”, “add an empty state”), preview on your own phone, and export the full Expo project whenever you want. The full method: how to build an app with AI.

How it makes money

Freemium by event count. Organizations (churches, leagues) will pay $10–20/mo; brides pay once — pick the recurring niche.
