How Much Does a Mobile App Cost? Prices, Ranges & Key Factors in 2026

Why there is no single answer to this question

Search "how much does a mobile app cost" and you will find articles quoting anywhere from €3,000 to €500,000. That spread is not an admission of vagueness, it reflects the actual market reality. A mobile app can mean a three-screen brochure with static content, or a full platform with multi-role authentication, online payments, push notifications, real-time sync and a management dashboard.

What matters is understanding which parameters move the price and in which direction. That is what this article covers.

The 6 factors that really drive the price

1. The number and complexity of screens

A simple screen (article list, static profile page) takes two to four times less time to build than a complex one: a content editor, an interactive map, a real-time data feed, a conditional multi-step form. Ten simple screens do not equal ten complex screens. An experienced developer estimates each screen independently based on its actual difficulty level.

2. Target operating system(s)

Building a native iOS app and a native Android app means building two separate applications with two codebases. The budget will be roughly twice that of a single-platform app. Cross-platform frameworks like React Native or Flutter allow sharing 70 to 90% of the codebase, which reduces cost without sacrificing quality on the vast majority of projects.

3. Backend and third-party integrations

An app connected to a third-party API (Stripe, Google Maps, an existing ERP) is very different from one requiring a dedicated backend built from scratch. The features that add the most to an estimate are: multi-role access management, push notifications, offline synchronisation, online payments and advanced geolocation.

4. Design quality and depth

A functional design built on existing component libraries (Material Design, Apple HIG) takes two to three times less time than a fully custom design with animations, micro-interactions and a proprietary visual system. This is not a style preference it is a deliberate budget decision that needs to be made during the scoping phase.

5. The type of team you choose

A freelancer, a specialised agency, an offshore development company and a product studio do not share the same daily rates, project management standards or contractual accountability. This single variable can explain a fourfold difference in cost for the same functional scope.

6. Post-launch maintenance and updates

Apple and Google release major OS updates every year. An unmaintained app can stop working within 18 to 24 months. Annual maintenance typically represents 15 to 25% of the initial development cost — a line item far too often missing from initial quotes.

Typical price ranges by project type

The figures below are market benchmarks for Western Europe in 2026. They include design, development and validation testing, but exclude annual maintenance and infrastructure costs.

Focused MVP — €5,000 to €25,000

Single platform (iOS or Android), 5 to 10 screens, clean design using standard components. Suited to validating an idea before investing further. Typical timeline: 4 to 8 weeks.

Standard application — €25,000 to €80,000

iOS and Android via React Native or Flutter, 15 to 30 screens, dedicated backend, polished design, authentication, push notifications, one or two third-party API integrations. Typical timeline: 3 to 5 months.

Complex or enterprise app — €80,000 to €200,000

Multi-platform, multi-role (customer, professional, admin), management back-office, multiple integrations (payments, ERP, CRM), real-time data flows, high security requirements. Typical timeline: 5 to 10 months.

SaaS mobile product or platform — €200,000 and above

Scalable multi-tenant architecture, analytics dashboard, multi-language support, high-availability infrastructure and a long-term product roadmap. These projects are typically run as a continuous product with dedicated teams.

Freelancer, agency or app factory: what is the real cost difference?

The choice of team is often the single biggest lever on total cost. Here is what each option means in practice.

The freelancer

A freelance developer typically charges between €350 and €600 per day. On a 50-day project, that is €17,500 to €30,000. The real risks: no dedicated project management, single-point-of-failure dependency, design and testing rarely included by default.

The specialised agency

An agency charges between €600 and €1,200 per day depending on size and positioning. The apparent premium covers project management, business continuity, design, QA and contractual protection. It is effectively insurance against cost overruns and last-minute surprises.

App factories and no-code platforms

Platforms like Bubble or offshore development shops offer very low upfront prices — €3,000 to €15,000. The app typically works for the initial scope, but customisation, migration or scaling costs quickly become prohibitive. This option can work for testing a very simple concept; it is not suitable for building a viable long-term product. The risk is having to start over if the project evolves.

What is often missing from quotes

A low quote frequently hides an incomplete scope. Here are the items regularly omitted, which represent on average 30 to 40% of the real total cost on a serious project:

• UX discovery and design phase (wireframes, prototyping, user testing): 10 to 15% of total budget
• QA and user acceptance testing (UAT, performance tests, testing on real devices): 10 to 15%
• Store submission (Apple Developer Program at $99/year, Play Store configuration, review and approval delays): €1,000 to €3,000
• Backend infrastructure (hosting, database, CDN, automated backups): €10 to €100/month depending on traffic
• Annual maintenance (OS updates, bug fixes, support): 15 to 25% of initial development cost per year

A project quoted at €30,000 often ends up costing €42,000 to €50,000 once all these items are properly accounted for from the start.

How to reduce cost without cutting quality

Reducing the cost of an app does not mean choosing a cheaper team. It mainly means reducing scope strategically. Here are five levers that actually work:

1. Define a strict MVP. Identify the two or three features absolutely essential at launch. Everything else can wait for version 2, backed by real user data.
2. Use proven third-party services. Stripe for payments, Firebase for authentication and notifications, Mapbox for maps. These are reliable, fast to integrate and far cheaper than building custom solutions.
3. Write a solid brief before asking for quotes. A prioritised feature list, rough wireframes and a clear technical context allow you to receive comparable and realistic estimates.
4. Work in sprints with delivery milestones. Avoid fixed-price projects without intermediate checkpoints. Sprints allow scope adjustment mid-project without losing budget control.

Real-world budget examples

Here are representative project profiles and the budgets observed on the Western European market in 2026, excluding annual maintenance.

Appointment booking app (B2C)

Authentication, geolocated professional listings, real-time availability, booking, push reminders. Observed budget: €15,000 to €25,000.

Two-sided mobile marketplace

Seller and buyer profiles, matching engine, rating system, secure payment, geolocation. Observed budget: €55,000 to €90,000. Dedicated backend, React Native, custom design.

Internal business app (logistics or field teams)

SSO authentication, dynamic offline-first forms, deferred sync, supervisor dashboard. Observed budget: €80,000 to €130,000.

SaaS app for teams

Multi-tenant, granular permission management, real-time dashboard, CSV/PDF export, webhooks. Observed budget: €150,000 to €250,000.

How to get a reliable quote for your project

For an agency or developer to give you a serious estimate, you need to provide at minimum:

• A one-page description of the problem being solved and the expected value for the end user
• A feature list with a clear distinction between must-have and nice-to-have
• Target platform(s): iOS, Android, or both
• Technical context: existing APIs, backend to build or already in place, any security constraints
• An idea of expected user volume at launch and at 12 months

The more precise the brief, the more reliable the quote — and the fewer surprises during the project. An estimate produced from a ten-minute call is worth nothing: it will either be too low to attract good talent or too high to cover real unknowns.

If your idea deserves to exist, it also deserves a serious brief. That is the best way to protect your investment from day one.
