Help & guide

No signal: the app still works

On the festival grounds the network dies all the time. The app is built for it: open it ONCE with signal (at the campsite, in the morning) and it caches everything by itself. After that, everything works offline.

1. Install it on your home screen

This is the essential step: it is what guarantees your phone KEEPS the data. See “Install the app” at the bottom of this page.

2. Everything renders offline

Grid, real-time, artist pages, map, who's-where, stats: everything stays readable with the last known data. The grid even keeps following the clock on its own.

3. Your actions are never lost

An “I'm going” vote, a drink order, an artist rating, your pin on the map: with no signal, everything is kept on your phone and sent automatically the moment the signal returns — even if you close the app in between.

The connection pill (top bar)

Green = connected. Amber = slow link (be patient, it's loading). Red = offline, you're seeing the last known data. “To send: N” = your pending actions, they'll go out on their own.

The day rollover

The festival day flips at 9 a.m.: at 9 the grid moves to the next day and, on the map, everyone resets to the campsite until the day's first show.

On your phone

Everything is built for touch. The handiest gestures, especially on the running-order grid:

Tap

Opens a band's page — photo, bio, who's going, ratings.

Double-tap

On a grid slot: marks “I'm going”, or withdraws if you already were. Works offline too — the vote is sent when the signal returns.

Pinch with two fingers

Zoom the grid in or out. The + / − buttons and the % (tap to reset to 100%) do the same; your zoom is remembered.

Drag

Scroll sideways for stages, up and down for times. The stage header stays pinned at the top.

Scroll down

The top menu hides to free up the screen; scroll back to the top to bring it back.

Light / dark theme

Tap the ☀️ / 🌙 in the top bar to switch between the dark theme and a light one that is far easier to read in bright sun. Your choice is remembered.

Reading the grid (colours)

A slot's border and pills tell you the essentials at a glance:

• GOJIRA
  Red border: the band is playing right now (Real-time view).
• GOJIRA
  Blue border: you voted “I'm going”.
• GOJIRA1ER
  Amber border + 1ER / PUIS badge: this slot clashes with another of your picks. 1ER = starts first, PUIS = comes next.
• 12Blue pill (bottom-right): how many people are going.
• 5Orange pill: how many “maybe”.

The map

• Drag to pan; pinch or use the +/− buttons (bottom-right) to zoom.
• Tap a point (entrance, bar, food, stage) to show its name.
• Avatar pins are people; tap a pin to see who's there.
• The ring colour says where the position comes from: red = placed by the person themselves (“I'm here”); green = inferred from the programme (the show they planned to see); amber = both at once.
• Programme-inferred positions are grouped under the artist playing: “3 personnes · Gojira” = three of the crew at Gojira. Open the pin for the list, with each person's spot (front, FOH…).
• At 9 a.m. (the day rollover) everyone resets to the “Back to camp” point until the day's first show — except people who placed their pin by hand.
• To place YOUR position: “Où es-tu ?” on the home page, or double-tap a stage on the map to pick your spot (front, back, FOH…). A hand-placed pin always wins over the programme guess.
• When you drop or move your pin it pulses (a slow fade) while it saves to the server, then goes solid once confirmed — so you always know whether your position has synced.
• The “Filtres” button shows or hides people (per person), hand-placed positions, programme positions, and stages.

The drinks counter

• On the home page, the “+1 🍺” button logs your order (pitcher, glass, ricard, tequila, soft). It counts for you and for the crew's day — the leaderboard is on the Stats page.
• A short anti-double-tap delay locks the button for a few seconds after each +1 — no need to insist, it's intentional.
• No signal at the bar? Tap anyway: the +1 is kept on your phone and goes out on its own when the signal returns.

Real-time

Real-time draws a red Live line across the grid and auto-scrolls to it, so you see what's playing and what's next. The line follows the clock even offline, and the grid flips to the next day at 9 a.m.

Reading an artist page

Every band has a page — open it from the artists list or by tapping a slot in the grid.

Genres, country, year

The tags under the name: style, home country and year formed, when known.

I'm going / Maybe / Remove

Say whether you're going. Your choice appears everywhere instantly — grid, list, stats. “Remove my vote” undoes it.

My spot

Mark where you'll be in the crowd (left, right, middle, front, back, FOH) so friends can find you.

Ratings: studio · live · pogo

Rate the band out of 10 on three axes — studio, live show and pit energy (bruises / broken ribs) — with a note if you like. The crew average shows above.

Who's going

Everyone who voted, split into “going” and “maybe”.
