The app is already built. It needs your festival.

Lineup, site map, personal timetable, live location between friends, official alerts and the forecast, in one native application for iPhone and Android. It runs today. What changes for your event is the name, the artwork and the data behind it.

Talk about your festivalSee what it does

What a visitor actually holds.

Every screen below is a real capture of the application, running an edition called Celestia. Celestia is not a client and never happened: it was invented for this page, which is the honest way to show you the whole product without putting somebody else's festival on the internet.

The mark of Celestia, the festival invented for this page

Your main stage, in motion

The main stage on the first screen is not a picture: it is drawn and lit and moving, built for this edition. Every festival gets its own, made from your artwork, so the application opens on the thing people bought a ticket for.

The Celestia home screen, showing the set playing now and the latest festival news

They open it and know what to do next

What is playing right now, on which stage, until when. Your news under it and your links one tap away. The first screen answers the question everybody on site is actually asking.

The Celestia lineup, listing each day's artists with their stage and start time

The whole lineup, day by day

A timetable or a timeline, searchable by artist and stage, filtered by genre, opening on today. One tap puts an artist into a visitor's own schedule.

A personal Celestia timeline, showing two starred sets against the current time

Everybody builds their own festival

Star the artists they came for and the timetable becomes theirs, with overlapping sets flagged rather than discovered at the barrier, and a reminder before each one at a lead time they choose.

The Celestia map: a drawn festival site with its stages, paths and points of interest, and the visitor's own position on it

A map of your site, not a pin on a road map

Your own artwork, your stages, bars, toilets and exits, filtered by category, with the visitor drawn on it where they are standing. Tap a stage and its schedule opens.

The Celestia home screen before the event, with a countdown and the weather forecast

It earns its place weeks before the gates

A countdown to the first set, the forecast for each festival day, the news as it lands, and tickets and travel where people go looking for them. Installed early, opened all the way through.

Not a demo. A product.

Each line below is a capability the application has, written down as a behaviour contract before it was built. You would not be paying to invent any of it.

Before the gates open

  • The full lineup by day, as a timetable or as a timeline
  • Search by artist or stage, filter by genre
  • Favourites, and a personal schedule built out of them
  • A warning when two favourites overlap
  • A reminder before a favourited set, at the visitor's own lead time
  • Curated playlists for the edition
  • The festival's news feed, read inside the app
  • Tickets, travel, merchandise, terms and FAQ, wherever you host them
  • A countdown to the first set
  • The forecast for each day of the festival

On site, on the day

  • Your own map artwork, not a road map with pins dropped on it
  • Stages, bars, toilets, exits and the rest, filtered by category
  • The visitor's own position, drawn on your map
  • Which stage they are standing near, and who is playing on it
  • Tap a stage, get that stage's schedule
  • Live location shared with friends, by code or by link
  • Direction and distance to a friend across the site
  • Group chats for the festival and for each stage, read in realtime
  • A photo hub the crowd fills, with reporting and removal on every picture
  • Every upload screened automatically before it appears, and whatever it flags queued for someone of yours to approve or reject
  • What is playing now, on the lock screen, without opening anything
  • Official alerts, safety messages included, at any hour
  • An artist page with their set, their other appearances and what clashes with it

For whoever runs the festival

  • One build becomes another festival: name, artwork, colours, tabs and links all arrive as data
  • Several editions, so next year is a configuration and not a new project
  • Sponsor and partner logos in tier order, identical on both platforms
  • A message pushed to everyone, at any moment you need it
  • Before, during and after the event, each enabling only what makes sense then
  • Links that open the right screen, from your site, your mails and your posters
  • iOS and Android off one shared core, each still natively written
  • App Store and Play Console submission, review and release, not just a build

That is a starting price, not a final one. Every festival edition begins there, and where it lands depends on how much of the list above you switch on, how many editions you run, and whether your event needs something that is not on it yet. You get the number for your own festival after one conversation, and you get it from the person who would build it.

And none of that is the ceiling.

Everything above already exists, so the next thing does not have to be invented from nothing. Whatever your festival wants its crowd to do can be built on top of this, and working that out is the part I enjoy most. Bring the idea, however rough.

One build. Every edition.

The application does not know it is Celestia. The name, the colours, the artwork, the map, the tabs, the links and the whole lineup arrive as data, which is why a second festival is a configuration rather than a second project, and why next year's edition is not next year's rebuild.

It does not know it is a festival either. An edition is a name, a set of days, a map and a lineup, and a venue season, a sports weekend or a three-day conference are the same four things under different words. If you run one of those, the question is worth asking.

A festival has already trusted us.

Appro built and shipped the application for Trolls & Légendes, a Belgian fantasy festival, on iPhone and Android. It has its own page on this site, with screens of both clients showing the same festival weekend.
