How much does it cost to build an app in 2025?

The question how much does it cost to develop a mobile app is probably the most common in any first meeting with a client, and also one of the most poorly answered by the industry. Online ranges span from €5,000 (templates) to €500,000+ (enterprise products), with no useful context to decide. The truth is that real cost depends on five concrete variables: functional scope (number and complexity of screens and features), technology stack (Flutter, dual native, React Native, hybrid), number of target platforms (mobile only vs mobile+web+desktop), depth of integrations with external systems (ERP, CRM, payments, APIs), and the quality and performance level required (professional product vs functional prototype). Without defining these five variables, any quote is guesswork.

Real market ranges in Europe for 2026, by typology, are: a simple Flutter MVP (iOS+Android, 5-8 screens, basic backend, authentication, one main integration) starts at €25,000-€40,000 with a senior agency and 3-4 months of development. A medium MVP (10-15 screens, subscriptions, push notifications, analytics, user roles) sits between €50,000 and €90,000 with 4-5 months. A complete product (feature-rich app, web admin backoffice, multiple integrations, multi-language, CI/CD, automated QA) typically lands at €120,000-€250,000 over 6-9 months. Enterprise products with regulatory compliance, high-load performance, complex legacy integrations and contractual SLAs start at €250,000 and can exceed half a million depending on scope.

The factors that push price up most significantly are, in order of impact: integrations with banking systems, proprietary ERPs or undocumented APIs (can double the backend cost); high-performance requirements with complex animations or real-time data management; multi-language with more than 4 languages and regions (affects design, content and testing); regulatory compliance (deep GDPR, HIPAA, PCI-DSS, sector-specific); offline-first experiences with complex synchronisation; and the late addition of features during development — the classic «while we're at it…» that typically adds 20-40% to the original budget. Factors that lower the price, on the other hand, are deep prior discovery (less rework), unified stack (Flutter for mobile+web instead of three codebases), MVP with rigorous scoping and reuse of proprietary components validated in other projects.

The most reliable way to get a real number before committing the full project is to run an initial Product Discovery phase (2-4 weeks, €4,000-€10,000) where the user is researched, the product hypothesis is validated, the MVP is defined with explicit scope criteria, the technical stack is chosen and each feature is sized. The output is a binding fixed-price quote — not an estimate — with a detailed timeline per sprint. This process has enabled Dribba to deliver over 300 projects while maintaining an average budget deviation below 10%, versus industry averages of 30-50%. If you're considering building an app, the most useful advice is: invest first in understanding well what you want to build and you'll save multiples during the subsequent development. A first meeting with Dribba is no-commitment and gives you an honest range in under an hour.
