How much does it cost to develop an app in 2026? Real prices and what drives them

It is the first question almost everyone asks: "how much does an app cost?". The honest answer is "it depends", but that does not help. So here are real ranges, what makes a project more expensive, and how to cut cost without building something fragile.

An app for booking appointments does not cost the same as a marketplace with payments, geolocation, chat and an admin panel. The difference is not "more screens"; it is more logic, more integrations and more things that can break.

Real price ranges in 2026

These ranges are for a custom app with a single codebase (Flutter) for iOS and Android, including design, development and publishing. They vary by country, team and scope, but they are a useful starting point:

• MVP or validation: €3,000–€10,000. The minimum to test the idea with real users: few screens, one core feature and a simple backend.
• Full app: €10,000–€30,000. Several screens, user accounts, notifications, payments and an admin panel.
• Complex product: €30,000–€80,000 or more. Marketplace, real time, ERP/CRM integrations, AI, advanced roles and security requirements.

What drives the price (and what does not)

Understanding what moves the budget helps you prioritise. The biggest cost drivers are:

• The number of distinct flows, not the number of pretty screens. Every new flow usually means logic, state and edge cases.
• Custom design versus a template. A bespoke design system adds cost, but it shows in the experience.
• The backend and real-time data. Sync, permissions and consistency are where the real effort goes.
• Integrations: payments, maps, AI, ERP, CRM, messaging. Each one adds dependencies and testing.
• Auth and roles: a single user is not the same as customers, drivers and admins with different permissions.
• Compliance and stores: GDPR, privacy, permissions and the App Store and Google Play listings.
• Maintenance: an app does not end on launch day.

The cost nobody tells you about

Development is the biggest part, but not the only one. Budget for:

• Store fees: €99/year on Apple and a one-time €25 on Google Play.
• Maintenance: 15% to 20% of the initial cost per year, for updates, bugs and new iOS/Android versions.
• Backend and services: Firebase, AI APIs, maps or email. Usually small at first, but it grows with users.
• Marketing and ASO: without it, nobody discovers the app no matter how good it is.

Freelancer, agency or product: what changes

A freelancer is usually cheaper and more direct, but depends on one person. An agency costs 1.5 to 3 times more for the structure, but covers design, development and support. The middle ground is a senior profile who acts as a fractional CTO and builds with a small team: you pay for the result, not for the structure.

How to cut cost without sacrificing quality

• Start with an MVP: build only what validates your hypothesis and leave the rest for phase 2.
• One codebase: Flutter for iOS and Android avoids paying for two builds.
• Use managed services: Firebase or Supabase before running your own infrastructure.
• Invest in the backend and security from the start: the expensive part is not doing it right, it is redoing it.
• Launch, measure, then invest. Each phase should pay for itself with what you learn from the previous one.

How to ask for a quote (and compare)

For two quotes to be comparable, always ask for the same things: scope by flows (not screens), platforms, integrations, timeline, and exactly what is included (design, testing, store publishing, post-launch support). If one quote is half the price of the rest without changing the scope, something is usually missing.

Conclusion

The cheapest app is not the one with the lowest price, but the one built right the first time. An honest MVP of €3,000–€10,000 can validate your idea; a full product rarely costs less than €10,000. What matters is that the price is tied to a clear scope and a business outcome, not to an endless feature list.
