How Much Does It Cost to Develop a Mobile App?

Mobile app development costs span a wide range — $10,000 for a simple single-platform MVP built by a freelancer in Eastern Europe, to $500,000 or more for a complex enterprise product shipped by a full agency team. The gap isn’t arbitrary. Here’s what drives it.

App Complexity Tiers

Simple apps ($10,000–$50,000): Typically 5–15 screens, one platform, no complex backend logic. CRUD operations against a database, basic authentication, standard UI patterns. A small team can ship this in 6–12 weeks.

Moderate complexity ($50,000–$150,000): Custom UI, 15–40 screens, real-time features (chat, notifications), third-party integrations (payment processors, maps, analytics), admin dashboard. Requires a frontend developer, backend developer, and designer working in parallel over 3–6 months.

Complex apps ($150,000+): Multiple user roles, complex workflows, offline functionality, IoT integration, AI features, regulatory compliance (healthcare, finance), or multi-platform delivery (iOS + Android + web). Projects at this tier run 6–18 months.

What Moves the Number

Platform. Native iOS and Android development is two codebases. React Native and Flutter are one, but they add toolchain complexity and occasionally hit platform-specific limitations that require native code anyway. Budget roughly 40–60% more for dual-platform native vs. cross-platform.

Backend complexity. A mobile app that reads from a simple API costs less than one that requires a custom backend with complex business logic, real-time data sync, background jobs, and a separate admin interface.

Team location. Senior developer rates vary from $30–$60/hour in Eastern Europe and Southeast Asia to $150–$250/hour in the US and UK. A 1,000-hour project costs $30,000–$60,000 at Eastern European rates and $150,000–$250,000 at US rates. Quality varies with selection process, not geography.

Ongoing costs. Development cost and total ownership cost are different numbers. Apple Developer Program: $99/year. Google Play: $25 one-time. Server costs depend on architecture and traffic. Expect to spend 15–20% of initial development cost per year on maintenance, updates, and OS compatibility.

What to Prioritise in the Budget

Build the MVP first. Define the minimum feature set that validates your core assumption, build that, ship it, and let real user behaviour inform what to build next. Teams that scope too broadly on the first version spend the most and learn the least.

Pick a development partner based on their track record with your app type, not on the lowest quote. A partner who has shipped a transactional fintech app will save you weeks on the payment and compliance decisions. A general-purpose dev shop will discover those problems at your expense.
