How to build an event planner app for iOS
What an event planner app needs
- Events with date, time, location, and details
- Schedules or agendas, and guest lists with RSVPs
- Reminders and calendar integration
- Optional ticketing for paid events (Stripe)
- A map for the venue (MapKit)
- A backend so attendees share the same schedule (Supabase)
There are two flavors: a personal planner for your own events, guests, and to-dos, and a ticketed-event app where attendees buy entry. The MVP slice for either is events, a schedule, and RSVPs. Add ticketing or vendor coordination after.
Core screens and data
An event planner app needs an event list, an event detail with a schedule, a guest list with RSVPs, a create-event flow, an optional ticket purchase, and a venue map. Here is what each screen does and stores.
| Screen | What it does | What it stores |
|---|---|---|
| Event list | Shows upcoming events an organizer or guest follows | Events, dates, roles |
| Event detail | Displays the schedule, location, and description | Event record, agenda items, venue |
| Guest list and RSVP | Tracks invites and yes or no responses | Guests, RSVP status, contact info |
| Create event | Lets an organizer set date, time, venue, and agenda | Draft events, schedule blocks |
| Ticket purchase | Sells entry to a paid event by card | Ticket orders, buyer info, Stripe reference |
| Venue map | Shows the location on a MapKit map | Venue coordinates, address |
| Reminders | Notifies guests before the event | Reminder times, notification settings |
Starter prompt
Paste this into AppFlight to generate the first version. It lists the screens, the shared data, and the two payment paths so the build matches the idea.
Build an event planner app for organizing and attending local events. An organizer creates an event with a date, a venue, and a schedule of sessions, then invites guests and collects RSVPs. Guests open an event to see the agenda, the venue on a map, and who else is coming, and they get a reminder before it starts. For paid events, sell tickets by card through Stripe, since a ticket to a real-world event is a real-world service, and add a small per-ticket fee. Store events, schedules, guest lists, and RSVPs in Supabase so everyone sees the same up-to-date plan. Offer a premium plan for organizers who want more events and collaborators, and sell that subscription through RevenueCat and in-app purchase.
How to build it with AppFlight
Describe it, for example: "An event app where an organizer creates an event with a schedule and venue, invites guests, collects RSVPs, sends reminders, and optionally sells tickets." AppFlight plans the screens, generates native SwiftUI, and runs it in a live simulator. Use the Supabase connector for the shared agenda and RSVPs, MapKit for the venue map, and the Stripe connector if you sell tickets. You iterate by asking for changes in plain language.
Monetization for an event planner app
Tickets to a real-world event are a real-world service, so Apple allows Stripe, often with a per-ticket fee. If you sell the planning app itself as a subscription, more events, collaborators, templates, that digital upgrade uses in-app purchase with RevenueCat. Ticket revenue and the app subscription are separate flows, so route each through the right method.
Shipping it to the App Store
When it works in the simulator, AppFlight signs the build, uploads to TestFlight so you can test RSVPs and ticketing, then submits to the App Store with metadata and screenshots. If Apple rejects the build, AppFlight reads the reason, fixes it, and resubmits. Apple reviews every app, so a submission is not the same as an approval, but the pipeline runs without you opening Xcode.
FAQ
Can an event app sell tickets with Stripe?
Yes. A ticket to a real-world event is a real-world service, so Apple allows Stripe rather than in-app purchase.
Can it sync schedules across attendees?
Yes. AppFlight connects Supabase so the agenda, guest list, and RSVPs are shared rather than stuck on one device.
How do I monetize a planning app?
Either a per-ticket fee through Stripe for paid events, or a subscription for premium planning features, which uses in-app purchase.
