Brussels Mobile Market

Picking an app developer in Brussels: what actually matters

What you'll pay for a mobile app in Brussels depends heavily on the platform you choose, how many features you need, and how the team is staffed. Senior developers at Brussels agencies generally bill from EUR 80-160/hr per day. The real differentiator isn't the number on the quote — it's whether an agency has shipped apps that actually retain users and hold App Store ratings above 4.2.

When comparing app studios in Brussels, ask for links to their actual App Store and Google Play listings rather than concept renders or static screenshots. Check that permission handling and data practices are built into the app itself, not outsourced to third-party SDKs with murky privacy standards. And confirm upfront who keeps control of the Apple Developer and Google Play accounts after handover.

Tkist Digital has delivered mobile app work for Brussels clients across fintech, healthcare, e-commerce, and on-demand services. Each completed project ships with live listings on both app stores, complete source code handover, and optional continued support at a flat monthly rate.

Cost Breakdown

What an app actually costs in Brussels

App budgets in Brussels shift a lot depending on the platform you pick, how much the feature list covers, and how the team is staffed. The figures below reflect current market rates as of August 2026, drawn from published agency portfolios and reported client spend.

MVP app

£8,000 – £25,000

4 – 8 weeks

  • Core functionality only, nothing you don't need yet
  • One shared cross-platform codebase (React Native or Flutter)
  • Minimal backend API to support the core flows
  • Live on both the App Store and Play Store

Tkist Digital MVP pricing starts at £8,000, built to get a real product in front of users fast.

Cross-platform app

£15,000 – £55,000

6 – 14 weeks

  • React Native or Flutter under the hood
  • A single codebase powering both iOS and Android
  • Custom-built UI component set
  • Push notifications plus usage analytics baked in

Our most common project type — typically 30-40% cheaper than building two separate native apps.

Native iOS app

£20,000 – £80,000

8 – 18 weeks

  • Built natively in Swift / SwiftUI
  • Follows Apple's Human Interface Guidelines closely
  • TestFlight beta rollout included
  • We handle the entire App Store review process

Worth it when a best-in-class iOS experience or deep platform integration is what sets you apart.

Native Android app

£18,000 – £70,000

8 – 16 weeks

  • Kotlin and Jetpack Compose under the hood
  • Built around Material Design 3
  • Internal test track configured on Google Play
  • Play Store submission and review handled for you

The right choice for markets where Android holds 80%+ of device share.

Progressive web app

£6,000 – £20,000

3 – 8 weeks

  • Installs straight from the browser, no app store listing needed
  • Works offline through service workers
  • Push notifications where the browser supports them
  • 95+ PageSpeed scores and solid Core Web Vitals

A strong fit for content or e-commerce products where getting to market fast matters most.

Enterprise app platform

£80,000 – £400,000+

4 – 18 months

  • Covers iOS, Android, and web at once
  • Advanced backend with real-time data pipelines
  • Enterprise-grade SSO and authentication
  • A dedicated, cross-functional delivery team

Usually the domain of firms like Thoughtworks and EPAM — outside what Tkist Digital typically takes on.

What moves the price up or down

Which platform you pick

Cross-platform frameworks like React Native or Flutter shave 30-40% off the cost compared to two separate native builds. Native is worth the premium mainly when you need platform-only APIs or a top-tier user experience.

How much backend is involved

A simple app running on Firebase for basic data reads and writes costs a fraction of one that needs real-time sync, complex business rules, or heavy integrations with maps, payments, or ML services.

Design and UI ambition

Leaning on standard Material Design or Apple HIG components keeps costs contained. A fully custom brand experience — bespoke components, animated transitions, micro-interactions — adds meaningfully to both design and build time.

How users log in

Plain email and password is the cheapest route. Adding Google or Apple social login typically adds about a sprint. Enterprise SSO via Okta, Azure AD, or SAML is a substantial project on its own.

Payments and in-app purchases

Brussels mobile teams generally charge around EUR 80-160/hr. Wiring up Stripe or RevenueCat usually takes 1-2 extra weeks. Regional payment gateways can take longer depending on how mature their APIs are.

Getting published

Apple's review typically takes 1-3 days; Google Play usually runs 3-7 days. Tkist Digital handles the whole submission process for every Brussels client. Budget $99/year for the Apple Developer Program and a one-time $25 fee for Google Play.

FAQ

Common questions about building an app in Brussels

Here's what Brussels businesses most often want to know before they commit to a mobile app project.

How much should a mobile app cost in Brussels?+

In Brussels, expect a cross-platform MVP to land around EUR 9,000, while a full native build for both iOS and Android can reach EUR 90,000+. Choosing React Native or Flutter over dual native codebases typically trims 30-40% off the total spend. Every Brussels project with Tkist Digital comes with an agreed fixed price before any development starts.

How long does it take to build a mobile app?+

A lean MVP typically moves from kickoff to App Store submission within 4-8 weeks. A more capable cross-platform build generally needs 6-14 weeks, while a dedicated native iOS or Android app runs 8-18 weeks. Complex enterprise-grade systems with heavier backend work can stretch across 4-18 months. Tkist Digital sets a firm timeline with clear milestones before any code is written.

Should I go native or cross-platform for my app?+

Most companies in Brussels are better served by React Native or Flutter: a shared codebase powers both iOS and Android, cutting build costs by 30-40% and easing future maintenance. Native Swift or Kotlin development earns its keep mainly when your app leans heavily on platform-specific APIs, elaborate animation work, or direct hardware access.

Does Tkist Digital manage App Store and Google Play submission?+

Yes, fully. Tkist Digital runs the complete submission process for both stores — preparing listing metadata, screenshots, privacy documentation, and responding to reviewer questions. Every build includes TestFlight and Google Play internal testing access, and developer account ownership passes to you once the project is finished.

Who owns the code once my project is finished?+

You do, entirely. Source code, developer accounts, API keys, and any connected third-party logins are handed over to you at project close. Tkist Digital keeps no licensing rights or ongoing obligations, and you remain free to hire any team you like for future development.

Does Tkist Digital take on Brussels projects remotely?+

Yes — Tkist Digital has delivered app builds for clients across Belgium and more than 40 other countries, entirely remotely. We coordinate through Slack or email, share design feedback in Figma, and handle testing via TestFlight or Google Play's internal channels, with no need for in-person meetings.

How we put this list together

Tkist Digital publishes and refreshes this ranking every month. We sit at #1 because we think we've earned the spot, but every agency on this page is measured against the same six criteria:

1

Real, published apps

We check the actual App Store and Google Play links. Screenshots or mockups don't count toward scoring.

2

Verified reviews

Reviews from Google, Clutch, and app store listings are cross-checked. Testimonials posted only on an agency's own site are excluded.

3

App performance signals

Public data on App Store ratings, crash indicators, and user retention feeds into the score.

4

Team size and delivery track record

LinkedIn headcount, Glassdoor insights, and client-reported delivery times serve as proxies here.

5

Pricing transparency

Agencies that publish starting prices or quote without demanding a sales call score higher.

6

Fit for Brussels projects

Whether the agency has real experience serving Brussels users — local payments, language, and compliance needs.

Last updated August 2026. Every agency here gets re-checked monthly.
