The Attendee App for Your Indico Conference

Indico runs your programme. HEPCon puts it on your attendees' phones to browse, search and save to their own schedule, offline, and keeps it in step with Indico.

552 attendees used it at ICHEP 2026, synced from CERN Indico

Going to a conference that runs on Indico? Install the free HEPCon app (App Store, Google Play). If the conference isn't in its events list, paste its Indico link on the Events screen: the programme is on your phone in about 30 seconds, offline, until at least a week after the conference ends.

Give Your Attendees What Indico's Timetable Can't Deliver

You chose Indico because it's the gold standard for call-for-papers, peer review, and timetable management at scientific conferences. But once the programme is set and attendees are on site, Indico's job is done — and the mobile experience gap opens up.

HEPCon closes that gap without adding work to your side. Share your Indico event link once, and your conference is published as an event inside the HEPCon app. You get push notifications, a live organiser dashboard, and an offline-capable programme your attendees can actually use in a crowded plenary hall with no Wi-Fi. Indico stays your system of record. Nothing in your workflow changes.

  • Tracks, sessions, contributions, abstracts, authors, and rooms — all imported
  • LaTeX formulas and large author lists rendered correctly
  • Live schedule updates pushed to attendees — you update Indico, we push the change
  • Full offline access — works in basements, field stations, and congested networks

Used at events on the Indico servers of CERN, DESY, Fermilab, IN2P3, INFN, Nikhef and Jefferson Lab, a university's own Indico, indico.global, and societies' own servers. See case studies →

What You're Left Managing When Indico Is Your Only On-Site Tool


  • The help desk queue grows at registration. Indico's nested timetable tree is built for conveners. On a phone during a coffee break, attendees can't navigate it — and they come to you.
  • You update the room in Indico. Attendees find out by accident. There's no push path from Indico to participants' phones. A room change means emails, notice boards, and confused clusters in the corridor.
  • The venue network collapses by mid-morning. Hundreds of attendees share the venue Wi-Fi, and Indico's timetable needs a connection. When the Wi-Fi slows, your programme is out of reach exactly when attendees need it.
  • Every attendee navigates parallel tracks alone. On a phone, a day of parallel sessions in Indico's timetable means zooming and scrolling sideways to compare what is on, which nobody does well in a coffee break.
  • Slide links and materials are buried. You've attached PDFs and proceedings in Indico. Attendees can rarely find them on site, so you get requests for the links after the event ends.
HEPCon solves all of these — without touching your Indico setup or duplicating the programme. Try it free with your Indico link → Curious what happens after you paste the link? How instant previews work.

What Your Attendees See Instead

Eight parallel sessions, one screen

The day's programme lists every session running at 14:00 with its room. Nobody pages through a PDF to find out what is on.

Each session with its talks in order

Open a session to see its room, its time, its convener, and the talks in the order they will be given.

A warning when two saved talks collide

Attendees save the talks they want into My Schedule. When two of them overlap, the app flags the clash.

From Your Indico Timetable to an Attendee-Ready View


HEPCon reads what your Indico event publishes and reshapes it for a phone screen — without losing structure, LaTeX, or large author lists.

How HEPCon Keeps Up with Indico


You keep working in Indico. HEPCon reads your event from Indico's export and keeps the app in step with it.

What comes across

Sessions, contributions, tracks, rooms, breaks, speakers, authors and attached files. Tracks become filters, sessions become the day's time blocks, and each talk carries its slides and papers. Contributions without a time slot, such as posters, are kept, and you decide whether attendees see them.

When you change Indico

HEPCon re-reads your event link on a schedule we set with you, works out what changed, and updates attendees' phones. Moved rooms and times are listed in the app under programme changes, and can go out as a push notification, sent by you or automatically.

A check before every update

If a sync looks wrong (the programme suddenly half empty, or a login page where the export should be), it is held instead of published until we have checked it. Problems in the export show as warnings on the sync card in your organiser dashboard.

For Indico administrators

What HEPCon Actually Touches (and What It Never Does)


The questions your IT and Indico admins will ask — answered up front.

  • Reads the event export, nothing else. HEPCon reads Indico's standard event export — for a public event, the same data your event page already publishes.
  • Any Indico instance. Not just CERN — events on DESY's, Fermilab's, Nikhef's and IN2P3's Indico, on the University of Münster's, on indico.global and on societies' own servers have run on HEPCon.
  • Timezone comes from Indico. Your event's declared timezone is treated as authoritative — times render correctly in the venue zone and in each attendee's own.
  • No plugin to install. Nothing is added to your Indico server, ever.
  • No server access, no admin credentials. The sync is a one-way read; HEPCon never writes to Indico.
  • Protected event? If your event's export isn't public, a read-only API token is enough, or talk to us about another way in.

When Your Speakers Come Back Next Year


Most physics conferences are part of a series. HEPCon was built for that.

ICHEP, EPS-HEP, CHEP, TWEPP, ACAT — each runs every year or every other year. Your speakers come back. Your reviewers come back. Your programme committees overlap. Most conference apps treat each event as an island and then move on. HEPCon does not.

When a researcher speaks at several conferences in HEPCon, their page lists every talk across the series under “Also at other events”, with their role and the conference name. They are matched by ORCID, INSPIRE-HEP or email, and one tap opens that talk in its own conference.

A matched speaker has one shareable link that works across conferences. How speakers are followed across events →

Indico + HEPCon, answered


Is there a mobile app for Indico conferences?

Yes. HEPCon is a mobile conference app that works alongside Indico. Paste your Indico event link and your conference opens as an event inside the HEPCon app in about 30 seconds. Attendees browse it fully offline, and nothing in your Indico workflow changes.

Does HEPCon replace Indico?

No. Indico remains your system of record for call-for-papers, peer review, and timetable management. HEPCon is the attendee-facing presentation layer — it imports your Indico programme and delivers it as a mobile-first, offline-capable agenda. Both systems run in parallel without any duplication of work.

How long does it take to add an Indico conference to HEPCon?

It takes about 30 seconds from a public event link: paste it, confirm by email, and your preview opens in the app. For a protected event we build it within 48 hours from a read-only API token or another route we agree with you. Evaluating with your live data is free, with no credit card; the go-live decision is due one week before your event.

Does HEPCon handle LaTeX formulas in Indico abstracts?

Yes. HEPCon renders mathematical notation correctly in talk titles and abstracts. Long author lists, special characters, and LaTeX-formatted content are handled natively — unlike generic event apps that strip or corrupt scientific formatting.

Does it work with our own Indico server, not CERN's?

Yes. Any Indico instance works: events on the Indico servers of DESY, Fermilab, IN2P3, INFN, Nikhef, Jefferson Lab and the University of Münster, on indico.global and on societies' own servers have run on HEPCon. Nothing is installed on your server.

What happens when we change the timetable in Indico?

HEPCon re-reads your event link on a schedule we set with you, works out what changed and updates attendees' phones. Moved rooms and times are listed in the app, and can go out as a push notification.
