From the first favourite to the next show
Visitors save their favourites and find their personal schedule. Reminders follow their choices, so the next show stays close without starting the search again.

The Celestia screens below are real captures of the application, running an invented edition. Celestia is not a client and never happened: it was made for this page, which is the honest way to show you the whole product without putting somebody else's festival on the internet. The Photos screen shows the shared gallery during a real event, supplied for this page. These screens show the full demo, including advanced features quoted separately and not included in Essential.

The main stage on the first screen is drawn, lit and animated for Celestia. A custom animated stage based on your artwork is an optional advanced feature, quoted separately and not included in Essential.

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.
Advanced features shown, on quote
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.
Advanced features shown, on quote
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.
Advanced features shown, on quote
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.

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.
Start with the Essential plan for the programme, favourites, reminders, supplied map and useful links. Choose additional visitor and organiser features according to your needs, with a separate quote.
Your name, logo and colours on the existing app foundation. You supply the programme, map and content in the agreed format. No bespoke development is included.
These features are not included in Essential. Their scope and price are agreed in a separate quote for your edition.
These organiser capabilities are quoted according to your needs. They are not automatically included in Essential.
Before launch, we check together that access, alerts, moderation and data handling fit your festival.
Have something else in mind for your festival? The possibilities do not stop with the features above. Tell me what you want the app to do: I would be delighted to design and build it with you.
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.
An email starts it, and it is answered quickly, by the person who would do the work.
