How to Choose a Scientific Conference App
A step-by-step evaluation process for academic and research events — how to define requirements, run vendor demos that reveal real capabilities, and avoid failures that only appear when the event is live.
Most conference app failures at academic events are predictable. They happen because the vendor evaluation was done on a demo that looked fine — and the real programme, real venue, and real constraints were never tested before the contract was signed.
This guide is about the evaluation process — not a feature checklist. It covers how to define your requirements, how to structure a vendor demo so it reveals real capability, and what red flags in vendor responses predict live-event problems.

Step 1 — Identify Your Dominant Constraint
Different scientific events fail for different reasons. Before talking to any vendor, identify which constraint dominates your event. This determines which requirements are non-negotiable and which are secondary.
Constraint: Data source
Your dominant problem is keeping the app in sync with your abstract or timetable system without duplicating work. Any vendor who requires manual re-entry of your programme is disqualified. Platform-specific integration guides: Indico, ConfTool, EasyChair, OpenConf.
Constraint: Venue and offline
Your dominant problem is connectivity — underground labs, shielded facilities, overloaded convention centre Wi-Fi. Any vendor whose offline mode is a cached homepage is disqualified. See the technical detail: Engineering & Technical Symposium requirements →
Constraint: Programme scale and density
Your dominant problem is navigating hundreds of parallel sessions fast. Any vendor whose demo event has fewer than 50 sessions is showing you a toy, not a product. Test navigation with your actual programme scale.
Constraint: Access control
Your dominant problem is restricting who can see what — internal events, NDA-covered content, invitation-only attendees. See: Internal R&D Summit guide →
Step 2 — Run a Demo That Reveals Real Capability
A standard vendor demo will always look fine. The vendor controls the event, the data, and the network conditions. To see real capability, you need to bring your own inputs.
Bring your own programme data
Ask the vendor to import a real export from your system before the demo — not their sample event, not a synthetic dataset. If they can't turn around a preview with your data within 48 hours, that tells you something about their actual setup process. A vendor who imports your data for the demo is demonstrating integration capability; one who defers this to "after you sign" is not.
Test at your programme's actual scale
If your event has 400 contributions across 8 tracks over 4 days, that is what you test. Ask: how does navigation behave when the full programme is loaded? How fast is search across all abstract text? Demo events with 20 sessions do not predict behaviour at 400.
Turn off the network during the demo
At some point in the demo, put the device in airplane mode. Then: open a contribution detail page, search for a word that only appears in abstract text, check your personal schedule, navigate to a room. The experience you get is the experience your attendees will have when venue Wi-Fi fails.
Test on the right devices
Your audience isn't using the latest iPhone in a conference room. Test on a mid-range Android from 2–3 years ago. If the vendor only demonstrates on a flagship phone, ask why.
Simulate a timetable change
During the demo, ask: "A room change just happened. Show me how that gets to attendees." You want to see: where the update is entered, how long it takes to propagate, and what the attendee notification looks like. A change that takes 20 minutes to reach attendees is not a room change notification — it's an email.
Step 3 — Questions That Separate Real Vendors From Marketing
Ask these directly. Vague answers predict vague products.
-
"What is the exact integration path with [your system]?"
The answer should name specific API endpoints or export formats, not "we support most platforms." -
"What does offline include — specifically?"
Acceptable: full programme, all abstracts, personal schedule, full-text search. Unacceptable: "the main schedule view." -
"Show me your largest current event by contribution count."
Scale claims without a live reference event are unverifiable.
-
"How long does it take a room change to reach attendees?"
You want seconds to minutes, not "whenever they next open the app." -
"What data do you collect about attendees, and can it be disabled?"
Academic events often have institutional data minimisation requirements. Know what you're agreeing to. -
"What happens on the day of the event if your servers go down?"
An offline-first app keeps working. An online-only app doesn't. The answer reveals the architecture.
Step 4 — Red Flags in Vendor Responses
- "We'll handle the data migration after you sign." Integration capability should be demonstrable before a contract. If they can't show you your own data in 48 hours during evaluation, they won't do it faster under contract pressure.
- "Offline works for the main features." Offline is binary for attendees — it either works or it doesn't. Partial offline means attendees will encounter broken experiences at the worst moments.
- "We support all platforms" without naming them. Ask to see the Indico integration, the ConfTool XML import, or the EasyChair export workflow specifically. "All platforms" that requires manual copy-paste is not integration.
- Demo event has fewer than 100 sessions. A vendor whose demo event is small has either never handled a large scientific event, or is deliberately avoiding showing you how their product performs under real conditions.
- Per-attendee pricing with no ceiling. A physics conference can have 2,000 participants. Per-attendee pricing that made sense for a 100-person corporate event creates budget uncertainty at research conference scale.
