The delegate-facing side of Rostrum: a mobile web app at your event's own address, with no app store, no download, and no install for anyone to fail at.
What it is
A branded web app served at /e/your-event. Delegates open a link or scan a QR code and are in. They can add it to a home screen, where it behaves like an installed app, and it keeps showing the agenda it has already loaded when the venue wifi gives out.
It is also where speakers and poster authors do self-service on their phones — checking their own presentations, uploading a replacement file, answering questions about their poster.
What it changes
The printed program stops being the source of truth, which means a room change at 9am is not wrong in five hundred people's hands by 9:05. Delegates build a personal schedule and get warned when their choices clash. Speakers stop needing a laptop to fix a file.
The badge QR
Print the event QR on badges and signage. One scan, an email code, and the delegate is in with a personal schedule.
The members-only program
Require sign-in and restrict to an uploaded allowlist, so only registered delegates can see the agenda.
The handout distribution
Set file access to handouts only, so delegates get the documents speakers meant to share without exposing every slide deck.
What you can do
Delegates get an agenda with a now-and-next strip, day picker and timeline or list view; session detail with speakers, files and sponsors; a faculty directory — everyone contributing content, speakers and abstract, poster and paper authors alike, each profile listing what they are presenting; poster, abstract and on-demand paper sections with Q&A and bookmarks where each applies; a personal schedule that flags overlapping bookmarks; cross-program search spanning sessions, faculty, abstracts and papers; a profile with communication preferences; and a feedback form.
Speakers, poster authors and paper authors additionally get "my presentations", "my posters" and "my papers" — upload or replace a file, read reviewer feedback, answer poster questions — all from the phone.
Staff get an allowlist manager and a QR-and-link panel on the Attendee App tab.
Settings
| Setting | What it controls | Default |
|---|---|---|
| Event URL slug | The event's web address, /e/your-slug. Lowercase letters, numbers and hyphens. Must be unique across every event. Also sets the event's own slug, so it drives the QR code and the shareable link everywhere. | From the event name |
| Access mode | Public to anyone with the link, or sign-in required. | Public |
| Restrict to registered attendees | Only emails on the allowlist may sign in. Manage the list on the Attendee App tab. | Off |
| File access | No downloads, handouts only, or every file. Enforced server-side, not hidden in the interface. | See warning below |
| Allow personal agenda | Delegates can bookmark sessions and posters into "My Schedule". | On |
| Show faculty profiles | The faculty directory and profile pages — speakers plus abstract, poster and paper authors. | On |
| Show session feedback | Surfaces feedback forms in the app. Requires the Session Feedback module; silently inactive without it. | On |
| Show abstracts | The abstracts section. Only active while Call for Abstracts and a live Abstract Viewer are on; the switch is locked with an explanation otherwise. | On |
| Show posters | The poster section. Only active while the Posters module is on. | On |
| Show papers on demand | The papers section. Only active while Papers on Demand and a live Paper Viewer are on. | On |
| Primary and accent color | Six-digit hex, with a color picker. Brands the app. | Blue / green |
File access is deliberately conservative until you choose: open the app settings and save the level you want — no downloads, handouts only, or all files.
Worth pausing on the widest option: all files means every deck a speaker uploaded, which some speakers will not expect to be distributed.
The poster section appears only while the Posters module is on; the abstracts section needs Call for Abstracts plus a live Abstract Viewer; the papers section needs Papers on Demand plus a live Paper Viewer; the session feedback option only functions with Session Feedback on. On top of that, each content section has its own show/hide switch here — so you can run a public poster gallery while keeping posters out of the app. A switch can never show what the modules do not provide, and none of this produces an error; an unavailable section simply is not there.
The faculty directory follows the same logic: poster, paper and abstract authors join it only while their sections are visible in the app, and a session must be published — visible and out of draft — before its presentations appear anywhere in the app at all.
A URL slug. Without one the app will not serve the event at all.
There is no native iOS or Android application. Offline means the agenda you already loaded keeps displaying — anything that needs the network, including bookmarks, uploads, questions and feedback, fails while offline. The allowlist is added one email at a time in the interface; there is no bulk upload, though the underlying service would accept one.
