What to look for in a congress app

When you choose a congress app, look at the delegate's day before the feature list: does the app turn a multi-hall scientific program into a personal program for each delegate, show travel and accommodation details per person, and help delegates find each other and sponsors stay visible? On top of that, the app should work alongside your existing abstract and accreditation systems and explain clearly how it handles personal data. The eight criteria below turn these questions into concrete things to ask every vendor.

Why a congress app is different from a trade fair app

At a trade fair the focus is on exhibitors and B2B meetings. At an academic or medical congress the scientific program sits at the center: parallel sessions running in several halls at once, panels, courses and oral presentation sessions, and dozens of speakers and moderators. Many delegates travel from other cities, and their flights and hotels are often arranged by the organizer or a sponsor company. Sponsors, in turn, want to be visible beyond their booth. For delegates, a congress is also where they meet colleagues and keep up with new work in their field.

That is why a general-purpose event app can fall short at a congress. Evaluate it against the congress's own flow.

Eight criteria

1. A personal scientific program

In a multi-hall program, the delegate's first need is to find the sessions in their field and put them together. The program should filter by day, hall and session type, and a delegate should be able to add a session to their own program with one tap. A printed or PDF program cannot change once the congress starts; in the app, a hall change or a cancellation should show up right away.

Ask the vendor: How long does a program change take to reach the app? How does a delegate see two sessions at the same time in their own program?

2. Speaker and session pages

Every speaker's photo, title, institution and short bio, and every session's time, hall, moderator and speakers, should be on one screen. Speakers should be able to follow their own session times and halls in the same place. Being able to jump from a speaker's page to their other sessions helps delegates build their program faster.

3. Reminders and announcements

A reminder before a session helps delegates be in the right hall. A hall change, a delay or a new announcement should reach everyone at once as a push notification. Keep the number of notifications in check: people switch off an app that notifies them about everything. Plan sponsored notifications within the same limit.

4. Travel and accommodation per delegate

Flight and hotel details for invited speakers and for delegates hosted by sponsor companies usually end up scattered across emails, spreadsheets and PDFs. In the app, each delegate should see only their own outbound and return flights, PNR and seat, hotel, and check-in and check-out dates. This also cuts down the "which hotel am I in?" questions your team gets.

Ask the vendor: How are travel details loaded in bulk? When a delegate's flight changes, how is the information updated?

5. Delegate networking

Physicians and academics working in the same field want to find each other at a congress. A delegate directory, messaging and meeting requests make it easier to plan those conversations between sessions. Delegates should decide for themselves who can see their profile. For an academic audience, details such as institution, specialty and interests are a good starting point for the right people to find each other; remember to ask for them at registration.

6. Sponsor visibility beyond the logo

A large share of a congress budget comes from sponsorship, and sponsors want to see what they gained beyond their logo. In-app company profiles, banner placements, sponsored notifications and sponsor frames on shared photos all add to that visibility. After the congress, you should be able to report how these placements performed.

Ask the vendor: Which placements can we offer sponsor companies as packages? Which data is reported per sponsor after the congress?

7. Working alongside abstract and accreditation systems

Most congresses already have an abstract submission and review system and an accreditation process. The app does not need to replace them. What matters is how the final program gets into the app and that delegates know which information lives where.

Ask the vendor: What is outside your scope? In what format, and by whom, is the final program loaded?

8. Data protection

A congress app processes delegates' names, institutions, contact details, travel details and photos. In most setups the organizer is the data controller and the app vendor is the data processor. Photo sharing based on face matching processes biometric data, which Turkey's KVKK treats as a special category of personal data with stricter processing conditions. Prepare your privacy notice and consent flows before the congress. This article is not legal advice; talk to your legal counsel about your own case.

Ask the vendor: In which region is the data stored? Is it encrypted in transit and at rest? Will you sign a data processing agreement?

Demo checklist

1. Have a two-day slice of your own program loaded into the demo; test it with your own hall and session structure, not sample data.
2. Sign in as a delegate and add one of three parallel sessions to your program.
3. Change a session's hall in the panel and see when the change appears in the app.
4. Enter one delegate's flight and hotel details and confirm another delegate cannot see them.
5. Ask where a sponsor appears in the app and which report they get after the congress.
6. If photo sharing is included, ask to see the consent flow screens.

Common mistakes

• Uploading the program as a PDF. Changes never reach delegates, and nobody can build a personal program.
• Announcing the app on the morning of the congress. Delegates build their programs in the days before; introduce the app with the registration confirmation and reminder emails.
• Offering sponsors only a logo slot. Visibility you cannot measure is harder to sell at the next event.
• Trying to solve everything with one tool. Instead of replacing the abstract system, be clear about what each tool takes on.
• Leaving data protection to the end. Consent texts should be ready before the registration form is published.

How Eventiqs helps

Congresses on Eventiqs usually start with Speaker Flow, My Calendar, My Travel, Smart Photo Sharing and the sponsor placements. Delegates see the scientific program with halls and speakers, add the sessions they choose to My Calendar and get reminders; their flight and hotel details appear in My Travel, visible only to them. Sponsors appear in the app through company profiles, banner placements and photo frames (sponsor placements). Your abstract and accreditation systems stay as they are; the final program is loaded into the panel. At TKBBV 2026, delegates created 300+ personal calendars, and the congress brought together 1,000+ attendees and about 100 sponsor companies (case study).
