Who it’s for

When the App Needs to Keep Pace with Event Production

My schedule changes, and attendees get outdated information

Rooms, times, and speakers can change after an announcement. Your team needs an agreed source for the schedule and a review process before updates reach the app.

My conference has multiple tracks and venues

Attendees need to find a session and know where it takes place. The schedule, speaker profiles, and map should use the same room and track names as the venue’s signs.

The date is set, and I cannot leave scope decisions until the last minute

Planning works backward from opening day through content, acceptance testing, and store submission milestones. Essential features take priority. Check-in, networking, and other integrations need a designated owner and acceptance criteria before they enter scope.

What we deliver

Attendee Information & Production Tools, Clearly Scoped

The list below is a starting point for defining scope. Check-in, sponsors, and integrations are options to assess during discovery, with owners, dependencies, and acceptance criteria agreed before contracting.

How it works

The Schedule Works Backward from Opening Day

  1. Discovery & scope prioritization

    We map attendees, rooms, registration, and the operations team. Discovery determines what must work at launch and identifies dependencies that could affect the schedule.

    Before committing to a launch date
  2. Design & sample content

    We validate navigation using representative sessions and maps. We agree who delivers content, by when, and how production checks changes after approval.

    Before finalizing essential workflows
  3. Development & rehearsals

    We deliver working software every two weeks. Acceptance testing includes attendees and production staff, with schedule-change scenarios and an agreed usage profile.

    Reference: MVP 4–6 weeks; complex projects 8–10
  4. Store submission & operations

    We plan store submissions early, with time for review. Third-party approval is not a guaranteed date. Content, incident response, and communication owners must be identified before opening day.

The Official CIAB FEBRABAN App

The public CIAB FEBRABAN case study documents an official app with a live schedule, speakers, and map, submitted and published on time, with 40,000 downloads during the event. Downloads do not equal concurrent attendees, check-ins, or sales leads. Your event’s technology, development timeline, and capacity requirements must be defined around its planned operation.

Pricing

What Determines the Cost of an Event App

We finalize the proposal after reviewing the schedule and operation. The event date alone does not determine price. The quote must include essential workflows, integrations, and rehearsals for that edition.

  1. Time available before launch. Late content, compressed acceptance testing, and external dependencies affect feasibility. Before pricing, we define a scope that fits the schedule without promising app store approval.
  2. Usage profile during the event. Total downloads and concurrent usage are different measures. Planning considers critical moments, such as opening and session changes, along with agreed testing criteria.
  3. Registration & check-in integration. Attendee lists, identification, and attendance records create their own workflows. Systems and access permissions must be understood before they enter the quote.
  4. Number of editions & content management. An app reused across events needs different content organization and permissions from a single-edition app. We define what will be reused and who manages the next edition.

After discovery, you receive a fixed scope, price, and timeline. Tell us about your operation and constraints so we can assess what belongs in the first release.

Event Website, Off-the-Shelf Platform, or Custom App?

CriteriaWebsite or off-the-shelf platformCustom application
Main needPublic information or a workflow already covered by the contracted product.An event-specific experience and integrations.
Attendee accessA website avoids installation. Check what your platform already offers.Installation should add value to the attendee journey and have a promotion plan.
OperationsYour team works within the vendor’s available options.Content, permissions, and workflows are defined in the contract.
ScheduleAccount for configuration time and content delivery.Include development, acceptance testing, and app store review.

If a responsive page with a schedule and locations meets the need, start there. An app should have a clear role in the experience beyond adding a step to check a session time.

Questions to Ask Before Committing to the Date

AskWhy it matters
What is the final deadline for submitting the schedule?Production and development need the same version and an agreed change process.
How do you distinguish downloads from concurrent usage?Install counts do not demonstrate capacity at peak times.
How much time is reserved for app store review?Approval depends on third parties. The schedule needs to account for that dependency.
Who changes a room during the conference?The on-site team needs to know who to contact and how to check the published update.
Can we use the app for the next edition?Reuse, accounts, and content organization should be defined in scope.
Common mistakes

Mistakes That Disconnect the App from the Real Event

  • Leaving store submission until event week. Plan submission, app store materials, and time for adjustments during discovery.
  • Confusing installs with capacity. Define a usage profile and rehearsal criteria. Downloads are not a guarantee of concurrent capacity.
  • Building a schedule without a content owner. Agree who approves times, rooms, and speakers, and how changes reach attendees.
  • Adding networking before validating the user journey. Profiles, moderation, and data add scope. Confirm the need before including them.
Built with Megaleios offers mobile development with Flutter and React Native. Technology and integrations are selected during discovery around attendee journeys, content updates, and the organizer’s systems.
FAQ

Event App Questions

How much does an event app cost?

Discovery establishes the fixed price based on launch date, content, usage profile, integrations, and number of editions. Share your schedule and registration platform so we can assess a comparable scope.

How long does it take to build?

Our mobile development reference is 4–6 weeks for an MVP and 8–10 for complex projects. The full schedule includes discovery, design, acceptance testing, and store submission, and must be checked against the event date.

Do you guarantee app store approval before my event?

App store review depends on third parties. Discovery plans lead time, materials, and room for adjustments. We commit to the agreed scope and work schedule.

Can I change the schedule after the app launches?

Schedule management can be included in the contracted dashboard. We define what production can update, who approves it, and how to communicate a room or time change.

Does the app include check-in?

It is an option to assess alongside accreditation and the registration system. Including it requires defining attendee identification, entry records, and each system’s responsibilities.

Do 40,000 downloads mean 40,000 concurrent users?

No. The CIAB FEBRABAN case study reports downloads during the event. Your project needs its own concurrent usage profile and capacity testing criteria.

Can we reuse the app for our next edition?

Reuse can be planned through edition-specific content and permissions. Discovery and the ongoing development plan must specify what stays and what changes.

Will I own the code?

Yes. Source code and documentation transfer after full project payment. App store accounts and maintenance responsibilities are agreed when contracting.

What happens after launch?

A 60-day warranty covers bug fixes. Support during the event and work on future editions must be explicit in scope. Ongoing development can continue under a monthly plan.

Do you work with companies in Brazil?

Yes. Megaleios is a U.S. company based in Orlando and serves businesses in Brazil and the United States, in English and Portuguese. We review the event schedule and local dependencies during discovery.
