How much does a mobile app cost in Belgium in 2026?

In Belgium in 2026, a mobile app costs anywhere from €5,000 for a focused MVP to well over €100,000 for a complex product built by an agency. The range is wide because it covers very different realities: how many screens, which platforms, what kind of back-end, and above all who builds it. My own projects start at €5,000 for an iOS and Android app built from a single codebase, and showcase websites start at €1,200. In this article I break down the real price ranges by project type, what actually drives the price up, the costs nobody mentions in the first meeting, and how to cut the budget without cutting quality.

Price ranges by project type

Let's start with the numbers I use myself, the same ones on my pricing page.

Showcase website or landing page: from €1,200. Design, development, SEO foundations, contact form. This is the entry point for a clean presence online. Expect more for rich multilingual content or heavily custom animation.

MVP mobile app: from €5,000. A working product, published on the App Store and Google Play, built around one main user flow. Sign-up, the core feature, payment if needed. Not ten modules, one that genuinely works.

Full application: €10,000 to €40,000. Multiple user roles, an admin back-office, notifications, integrations. Most serious business products live in this range.

Complex platform: above €40,000. Real-time features, heavy volumes, matching algorithms, multiple dashboards. These projects get priced after proper scoping work, never off the cuff.

An agency will position every one of these lines significantly higher. More on that below.

What actually drives the price

Four factors explain most of the gap between quotes.

The number of user flows. An app where people read content is simple. An app where users interact with each other, book, pay and get notified multiplies the screens, the states and the edge cases. Every added flow means design, code and testing.

The back-end. An app that shows live data needs a server, a database and account management. Users never see this layer, and it often represents half the work.

Integrations. Payments, calendars, wearables, existing business tools: every external system means connection work, error handling and maintenance. On Nova Sport, syncing challenges with 18+ smartwatch brands was a project of its own: the case study covers the product.

The level of finish. Going from "it works" to "it feels obvious and smooth" easily takes a third of the budget. It is also what separates the apps people keep from the ones they delete.

Agency vs independent developer: two cost structures

The same requirements can come back with an €8,000 quote and a €60,000 quote. That is not a scam. It is a difference in structure.

An agency bills a team: project manager, designer, developers, tester, the salesperson who signed you, plus a share of the office. That is the price of an organization able to absorb large projects. In Belgium, serious agency app projects rarely start under €25,000, and ambitious custom work climbs past €100,000 quickly.

An experienced independent developer covers design, code and release alone. No internal coordination to finance, no intermediary margin. The budget goes into the software itself. The trade-off is real: one person means limited capacity, and availability you should verify. For a first product or a tight budget, the equation usually favors the independent.

The hidden costs nobody quotes

Development is not the end of the story. Plan for these lines from day one.

Developer accounts. Apple charges $99 per year, Google $25 once. Without them, no release.

Hosting and services. Server, database, email delivery, file storage: from a few euros to a few hundred euros per month depending on usage.

Maintenance. iOS and Android change every year. An app left without updates eventually breaks, usually at the worst moment. Budget for regular, even light, upkeep.

Evolutions. Your first users will ask for things. That is a good sign. But every change is work: set aside an envelope for the first six months instead of discovering each invoice.

An honest provider tells you about these costs before you sign. If nobody brings them up, ask.

How to lower the price without lowering quality

Cutting budget does not mean cutting reliability. These are the levers that work.

Cut features, not quality. An app with three excellent screens beats an app with twelve mediocre ones. Launch the core, measure, then extend.

One codebase for iOS and Android. Mature cross-platform technology nearly halves the work compared to two separate native builds, with no perceptible difference for users in the vast majority of cases.

Arrive with decisions made. Every round of hesitation costs hours. A clear brief, examples of apps you like, a prioritized list: that is budget saved.

Beware of extreme low-cost. A €1,500 app built on a generic template gets paid for twice: once at the order, once at the rebuild.

How I quote

My method has three steps. A free 30-minute call to understand your project and constraints. A written scope, in plain language, listing what is included. A fixed quote: the number you approve is the number you pay. No day rates, no running meter. After 7+ years and products used by 180,000+ people, I know what a feature really costs to build, and I would rather turn down a project than underprice it.

Have an app idea and need a reliable number? Tell me about your project: you leave with a clear scope and a written quote.
