Event & Conference App Development
Custom event and conference apps attendees actually open — their ticket, agenda, networking, live Q&A and venue map in one place, working even when the venue wi-fi does not.
Looking for the app for an event you are attending? You will find the link in the organiser’s confirmation email.
TRUSTED BY TEAMS
Most event apps are installed the night before and deleted the day after, because they offer nothing attendees cannot find elsewhere.
Sodio is an event app development company building custom event and conference apps that people keep open: their ticket inside, a personal agenda, networking and meetings, live Q&A, maps that work offline, and one app that carries every event in an organiser’s calendar — so it is still on the phone when the next one is announced.
/// IS CUSTOM RIGHT FOR YOU?
When an Event App Builder Is Enough
Event app builders such as Whova, Swapcard and EventMobi produce a good app for a single event quickly. If that is what you need, use one. A custom event app earns its place when the app is part of how you run your events, not just one of them.
An app builder fits when
- You run one event, or a few unrelated ones
- A standard look and feature set is enough
- Registration and attendee data can live in the builder
- You need an app for your own events
A custom event app fits when
- You run recurring flagship events, or a whole calendar of them
- The app is part of your brand and your sponsors’ offer
- The app must work closely with your registration, CRM or membership systems
- You are an event company or agency offering apps to your clients

/// GETTING ATTENDEES TO OPEN IT
Getting Attendees to Open the App
An event app is only as valuable as the number of attendees who use it.

///AI IN EVENT APPS
Where AI Helps an Event App
An event app knows what each attendee is interested in, where they are and who they have met. That is what makes AI genuinely useful inside it.
People worth meeting
Attendees introduced by shared interests and goals, even when none of them have met before.
Sessions worth attending
A personal agenda suggested from each attendee’s interests across a multi-track programme.
An assistant that knows the event
Questions about rooms, timings, food and policies answered at any hour from the event’s own information.

/// COST AND TIMELINE
What Drives the Cost and Timeline
A working event app on iOS and Android typically arrives within 30 days, with a production version in 90. For a fixed event date, the build is planned backwards from opening day, including app store review time.
The cost moves with six things: whether it runs on iOS, Android, the web or all three; integration with registration, ticketing and CRM systems; networking and video meetings; indoor venue maps; offline working; and whether it carries many events or is offered as a white label app to other organisers.
/// FAQ
Frequently Asked Questions
An event app is the mobile app attendees use before, during and after an event: their ticket, their agenda, speaker and session details, maps of the venue, networking and meetings, live Q&A and polls, and messages from the organiser. A conference app usually adds features for exhibitors, sponsors and continuing education.
Only when the app holds something they need. Putting the ticket, the personal agenda and networking inside the app gives people a reason to install it. For a short, single-day event, a mobile web app that needs no download is often the better choice, and we will recommend it when it is.
For most single events, an event app builder such as Whova, Swapcard or EventMobi is quick and sensible. A custom event app makes sense for recurring flagship events, for organisers who want one branded app across all their events, when the app must connect closely to registration, CRM or membership systems, or when sponsorship inside the app is a major source of revenue.
Yes, and it solves one of the biggest problems with event apps — being deleted the day after. A single app holds every event in your calendar. Attendees keep it installed, and each new event appears in it automatically.
It is an event app that runs entirely under your brand, often built so it can be reused across many events or offered to other organisers. Event companies and agencies use a white label event app to give every client a branded app without building each one from scratch.
The parts attendees need most do: the ticket, the agenda and the venue map are stored on the phone. Live features such as Q&A and messaging resume as soon as a connection returns.
