London event apps for exhibitions, corporate launches and hospitality venues.

Q: Should we build our own app or keep renting an event platform?

Renting suits one-off events; owning suits recurring shows. A licensed platform gets a single event live quickly. If you run the same show every year, or several shows, the fees recur while the data and the visitor relationship sit partly with the vendor. Building your own costs more at the start, but the platform, the attendee history and the brand in the app stores are yours for every future edition. A middle route also exists: a custom attendee app sitting on top of a registration system you already trust.

Q: Can exhibitors scan badges without buying hardware?

Yes, using the camera on their own phones. Exhibitor staff sign in to the app with a stand account and scan the QR code on visitor badges. Each scan creates a lead with the details the visitor agreed to share at registration, plus notes and tags the exhibitor adds. Scans queue offline when hall connectivity is weak and upload once the phone reconnects, so no lead is lost on a busy aisle. Organisers can still rent dedicated scanners for exhibitors who prefer them, and both feed the same lead records.

Q: How do you handle accessibility for London audiences?

We design to WCAG 2.2 and the Equality Act 2010 from the first screens. That means readable text sizes, screen reader labels, sufficient contrast and no actions that rely on colour alone. On the event side, attendees can record access needs at registration, find step free routes and request support. Venue access information is entered once and appears wherever it is needed, from the arrival guide to the session pages. We test with screen readers on both iOS and Android before release, not just with automated checkers.

Q: Do you also build event planning app development London agencies use internally?

Yes, as planning and production tools rather than attendee apps. Agencies often need run sheets, supplier bookings, approval trails, budget tracking and client sign off more than a public app. We build these as a private workspace for your producers, with a client view that shows only what each brand needs to see. It can sit beside an attendee app or run on its own. Permissions are set per producer, so freelancers see only the events they are booked on.

Q: Are you event mobile app developers London clients can visit?

We are not based in London and do not offer in-person meetings there. Our offices are in Dubai, Riyadh and Karachi. London clients work with us remotely: discovery sessions, design reviews and sprint demos happen by video call, and test builds go to your team's phones throughout the project. Shared project boards and written decisions mean nothing depends on being in the same room.

Q: How do you prepare the app for heavy traffic when registration opens?

With load testing and a release plan agreed in advance. Registration launches, early bird deadlines and the first morning of a show all create spikes. We size the hosting for your busiest expected hour, test it under simulated load and plan a staged release of push messages so they do not all land at once. You know beforehand who is watching the system on the key days. If a third party, such as a payment provider, has an outage, the app shows a clear message and keeps the queue rather than failing silently.

Q: What happens to attendee data after the show?

It stays in your accounts under the retention rules you set. We agree retention periods during discovery and build them into the admin, so old records are removed on schedule. Exhibitors receive only the leads that visitors agreed to share. Attendees who asked for no marketing stay excluded, and you can export or delete an individual's data when they ask, which UK GDPR requires. Aggregated, anonymised reports can be kept longer to compare editions year on year.

We take on event management app development London organisers need when an event involves thousands of attendees, exhibitors and sponsors arriving from across the capital and abroad. Codeeo builds registration, badge check-in, exhibitor tools, meeting scheduling and venue operations into one app, so your team runs the floor from phones instead of spreadsheets and radios.

London events are expensive to stage and unforgiving when entry queues build or a sponsor cannot see their leads. The app is planned around the moments that cost you most: arrival, the show floor and the follow up after everyone has gone home.

Scope your London event app Mobile app development

Built for: Exhibition organisers, corporate event agencies, venue operators and hospitality groups running ticketed or invitation-only events in London.
Typical timeline: Set in discovery against your show dates, with the exhibitor sales cycle and registration opening treated as earlier deadlines than the event itself.
What you own: Source code, store listings, admin panel, attendee and exhibitor data, all registered to your organisation rather than to us.

What the app can include

Tools for London shows where every minute on the floor is paid for.

A trade show at ExCeL London in the Royal Docks, a product launch in a converted warehouse in east London and a private dinner in Mayfair look like different businesses, yet they share the same pressure: the right people must get in quickly, find who they came to meet and leave with something to act on. Many attendees arrive by the Elizabeth line or DLR at Custom House, others by taxi from a hotel across the city, and some fly in that morning. The capabilities below are the ones London organisers ask us about most, listed starting with exhibitors and sponsors because that is usually where the revenue sits. A first release rarely needs all of them; discovery decides which ones pay back fastest for your format. We also ask early which features must work for a crowd that never installs the app, because some London audiences only ever use a web link.

Explain your project

Exhibitor portal and lead capture
Exhibitors manage their stand profile, upload brochures, register staff and scan visitor badges on their own phones. Leads arrive with notes and qualification tags, and exhibitors export them straight to their CRM. Organisers see which stands are active and which have not set up, while there is still time to chase them. Stand staff can be added or removed right up to opening.
Exhibitors leave with leads they can prove, which helps the rebooking conversation.
Registration with badge printing
Registration forms for visitors, delegates, speakers and press, each with its own questions and approval rules. On arrival, a QR code from the app prints a badge at a self-service kiosk, which keeps the morning queue short at large venues where several halls open at once.
Arrival queues shrink and every badge matches a registered record.
One to one meeting scheduler
Buyers and suppliers request meetings, accept or decline, and receive a table number and time slot. Matching can use interests captured at registration. For hosted buyer programmes this feature often justifies the whole app, because sponsors pay for meetings that actually happen.
Booked meetings, not chance encounters, become the measurable result.
Travel and arrival guidance
Directions from major stations and airports, entrance maps, cloakroom and step free route information, and arrival tips that can change on the day. Where useful, we connect to Transport for London's open data so attendees see relevant line status before setting out.
Fewer attendees arriving late and flustered after crossing the city.
Sponsor visibility and reporting
Sponsored sessions, banner placements in the app, branded push messages and a reporting view showing impressions, taps and session attendance. Sponsors receive a clear report after the event instead of an estimate.
Sponsorship packages are backed by numbers you can share.
Session agenda and live changes
Multi-stream agendas with personal schedules, room changes pushed to attendees, speaker bios and slides released after each talk. Capacity warnings tell attendees when a theatre is full before they walk to it.
Popular sessions stay safe and less popular ones get found.
Live ops dashboard for the floor team
A control view showing check-ins per entrance, hall occupancy, session fill rates and open support requests, refreshed in real time. Floor managers reassign stewards to a queue that is building, push a message to one hall only, and log incidents with photos and timestamps. At a multi-hall venue this replaces a dozen radio conversations with one shared picture.
Problems on the floor are spotted while they can still be fixed.
Hospitality and private dining bookings
For restaurants, bars and venues hosting events, the app handles private hire enquiries, timed seatings, deposits, menu choices and dietary requirements, with confirmations sent to every guest. Corporate hosts see their guest list and choices in real time.
Private events are confirmed with the details the kitchen actually needs.
Contractor and build schedule
Build-up and breakdown slots for stand builders, delivery bookings for loading bays, and rules documents in one place. Venue operations teams see who is due on site and when, which matters at busy venues with shared docks.
Build days run to the plan rather than to whoever arrives first.
Privacy controls for attendee data
Consent recorded at registration for each use of data, separate permission for exhibitor badge scans, and tools to answer access and deletion requests under UK GDPR. Marketing messages respect PECR, so a badge scan does not quietly become a mailing list subscription.
Attendee data use stays defensible if the ICO or an attendee asks.

Who this is for

Four London organisers who get the most from a custom app.

Off the shelf event platforms work well for many events. A custom app is worth it when your format, your commercial model or your data needs do not fit a template, or when you run a recurring show and want an asset you own rather than a yearly licence. These four profiles cover most of the London organisers we speak to.

Trade and consumer exhibition organisers

You run recurring shows with hundreds of exhibitors and need exhibitor self-service, lead capture, floor plans and a visitor app that carries your brand. Owning the platform lets you reuse it across every edition and every show in your portfolio. Event registration app development London exhibition teams commission usually starts with visitor sign-up and exhibitor onboarding, since those open months before the doors do. Floor plans can show stand numbers, sponsors and features, and update when a late exhibitor changes stand.

Exhibitor onboarding is often the first live feature.

Corporate event and experiential agencies

Your agency produces launches, summits and incentive events for brands, each with different looks and requirements. We build a white label app that takes a new skin and agenda per client, keeps every client's data apart and gives your producers one tool for guest lists, run sheets and live updates. Producers can clone last year's event, swap the branding and agenda and go live without rebuilding anything, which matters when your agency is pitching for repeat business.

Venue operators and hotel event teams

You sell your spaces to many organisers and want to give each one a consistent experience: enquiry, contract, floor plan, catering choices, contractor bookings and invoices. A client app for your venue reduces email back and forth and gives your sales team a clearer pipeline of upcoming events. Event planners booking your rooms can see availability, hold dates and sign contracts in the same place, and your finance team sees deposits and balances without chasing.

Hospitality groups with ticketed events

Bar and restaurant groups running quiz nights, tastings, live music or seasonal events across several London sites need booking, prepayment and guest messaging per site. The app gives guests one account across your venues and gives managers a view of covers and prepaid tickets before each night. Licensing for each site sits with its own borough council under the Licensing Act 2003, so we keep each site's details and conditions separate in the admin. Regulars can be recognised across sites and offered early booking.

From brief to show day: how a London event app gets built.

01Commercial discoveryWe start with how the event makes money, from exhibitor packages to sponsorship and tickets, and which features protect that income. Everything is done by video call with the people who sell and run the event.
02Attendee and exhibitor flowsRegistration, onboarding, lead capture and meeting booking are mapped as flows with every exception: group bookings, speaker changes, press passes and substitutions on the day.
03Interface and brand designYour event identity applied to readable, fast screens, tested on older phones too, because not every exhibitor arrives with the latest handset or a full battery. Contrast is checked for bright exhibition halls.
04IntegrationsConnections to your CRM, payment provider, badge printers, email platform and any registration system you already use, built and tested against real sample data.
05Rehearsal and releaseA full dress rehearsal with your staff scanning test badges, booking test meetings and pushing test messages, then store submission timed well ahead of registration opening.
06Post-show reporting and next editionExhibitor reports, sponsor results and attendee feedback compiled after the show, followed by a review of what the next edition's release should improve.

How we work together

Three ways London teams engage us.

Codeeo does not have a London office. Our team of 80+ is based in Dubai, Riyadh and Karachi and works remotely with London clients, running every workshop, review and demo by video call. The usual model is a fixed scope first release for one event, then a retainer that carries the platform from edition to edition. Organisers with a full portfolio of shows sometimes take a dedicated team. We have delivered 200+ projects across the UAE and the US, and clients rate us 4.7 from 23 Google reviews. Every engagement starts with a written scope, so you know exactly what the first release includes before any design work begins.

Fixed scope

A defined build with a deadline

We agree what the product has to do, write it down with a price and a date, and build exactly that. Changes are priced before they are made, not discovered on the invoice.

What London organisers ask before commissioning an event app.

What drives the cost of event management app development in London?

Mostly the number of user types and integrations, not the number of screens.

An app for attendees alone is a different size from one that also serves exhibitors, sponsors, speakers, contractors and venue staff. Each integration, such as a CRM, badge printers or a payment provider, adds build and testing time. Live features like meeting matching and lead capture add more. We price after discovery, once these choices are written down, so you can trim scope rather than guess. Timing works the same way: fewer user types and integrations mean an earlier first release.
