The short answer: somewhere between $5,000 and $500,000.
That range is useless, which is why you're still searching. The real answer depends on four things: what the app does, who builds it, where they're located, and how well the code is structured underneath the screens.
This guide breaks down each variable with real numbers from industry surveys and market data. No hand-waving, no "it depends" without explaining what it depends on.
| Agency | Specialization | Starting Price | Architecture | Source Code |
|---|---|---|---|---|
| Amgres | Flutter + Node.js | $4,900 | Clean architecture | Included, you own it |
| Surf | Flutter, enterprise clients | $25,000+ | Varies by project | Negotiable |
| Very Good Ventures | Flutter, Google partner | $50,000+ | Custom per engagement | Included |
| GeekyAnts | React Native + Flutter | $15,000+ | Standard MVC | Included |
| Miquido | Flutter + AI integration | $20,000+ | Depends on team | Included |
The quick reference
If you need one table and nothing else:
| App Complexity | Price Range | Timeline | Example |
|---|---|---|---|
| Simple (3-5 screens, basic features) | $5,000 – $30,000 | 1–3 months | Content app, simple booking form, portfolio |
| Medium (5-10 features, API, payments) | $25,000 – $80,000 | 3–6 months | E-commerce, SaaS dashboard, booking platform |
| Complex (real-time, offline, integrations) | $60,000 – $200,000 | 6–9 months | Fintech, logistics, multi-role workflow apps |
| Enterprise (multi-tenant, compliance, infrastructure) | $150,000 – $500,000+ | 9–18 months | Banking platform, healthcare system, marketplace |

These ranges assume a single platform (iOS or Android). Cross-platform frameworks like Flutter reduce costs by 30-45% compared to building separate native apps (Statista 2025).
Cost by region: where your developer is located matters
The same app built to the same quality costs dramatically different amounts depending on where the development team is based:
Developer hourly rates by region (2026)
| Region | Junior | Mid-Level | Senior | Architect |
|---|---|---|---|---|
| United States | $60–$90 | $100–$150 | $150–$250 | $200–$300+ |
| Western Europe (UK, Germany, Netherlands) | $50–$80 | $80–$120 | $100–$180 | $150–$250 |
| Eastern Europe (Poland, Romania, Ukraine) | $25–$45 | $40–$70 | $50–$90 | $80–$150 |
| India | $15–$25 | $25–$40 | $40–$70 | $60–$100 |
| Southeast Asia (Vietnam, Philippines) | $15–$30 | $30–$50 | $40–$70 | $60–$90 |
| Latin America (Brazil, Argentina, Colombia) | $25–$40 | $40–$65 | $55–$90 | $80–$130 |

What this means for total project cost
A medium-complexity app (5-10 features, API integration, payments) requires approximately 600-1,000 development hours. At different regional rates:
| Region | 800 hours × average senior rate | Total estimate |
|---|---|---|
| US agency | 800 × $175 | $140,000 |
| Western European agency | 800 × $130 | $104,000 |
| Eastern European agency | 800 × $65 | $52,000 |
| Eastern European specialist (solo/small studio) | 800 × $50 | $40,000 |
| Indian outsourcing | 800 × $45 | $36,000 |
Same app. Same features. Same screens. The price difference is real estate, labor markets, and business overhead — not necessarily quality.
The quality difference comes from architecture and process, not geography. A senior developer in Romania or Poland writing Clean Architecture code delivers equivalent or better code quality than a mid-level developer at a US agency. The reverse is also true: a cheap outsourcing shop anywhere in the world can produce expensive-to-maintain code regardless of the hourly rate.
The architecture factor: the invisible cost multiplier
This is the variable most pricing guides ignore, and it's the one that determines whether your app costs $15,000 once or $15,000 per year forever.
Architecture quality tiers
| Tier | What it means | Upfront cost impact | 3-year maintenance cost | Who offers it |
|---|---|---|---|---|
| No architecture | Code works but has no structure. Business logic mixed into UI, database queries, everywhere. | Cheapest (baseline) | 3-5x original build cost | Budget freelancers, cheap agencies |
| Basic structure (MVC/MVVM) | Separation between screens and logic. Better than nothing, but business rules still scattered. | +10-20% over baseline | 1.5-2x original build cost | Most mid-range agencies |
| Clean Architecture | Layers: presentation, domain, data. Business logic isolated from frameworks and UI. Testable. | +20-35% over baseline | 0.5-1x original build cost | Senior developers, architecture-focused studios |
| Domain-Driven Design | Clean Architecture + explicit domain modeling. Business rules readable by non-developers. Full test coverage. | +35-50% over baseline | 0.3-0.7x original build cost | Specialists only — rare at any price point |
The pattern is consistent across every industry survey: higher upfront architecture cost correlates with dramatically lower lifetime cost. A 35% premium on a $15,000 build ($5,250 extra) saves $20,000-$40,000 over three years in reduced maintenance, faster feature additions, and smoother developer handoffs.
Conversely, the cheapest initial build is almost always the most expensive over time. AgileEngine's 2025 analysis found that poorly-architected projects can require 200-400% of the original cost in refactoring within two years.
Flutter vs. native: the cross-platform cost advantage
Flutter (Google's cross-platform framework) produces a single codebase that runs on both iOS and Android. This fundamentally changes the cost equation:
| Approach | Development hours | Teams needed | Ongoing maintenance |
|---|---|---|---|
| Native iOS + Native Android (separate codebases) | 1,200-1,600 hrs total (two teams) | 2 (Swift + Kotlin developers) | Two codebases to maintain, sync, and test |
| Flutter (single codebase) | 600-1,000 hrs total (one team) | 1 (Dart/Flutter developer) | One codebase, one test suite, one deployment |
| Cost savings with Flutter | 30-45% less than native | Half the team size | ~50% less maintenance overhead |

Flutter app costs specifically (2026)
| Complexity | Flutter cost range | Native equivalent |
|---|---|---|
| Basic (MVP, 3-5 screens, simple backend) | $5,000 – $25,000 | $15,000 – $50,000 |
| Mid-complexity (custom UI, APIs, payments) | $25,000 – $60,000 | $50,000 – $120,000 |
| Enterprise (offline, real-time, modular, tested) | $60,000 – $120,000+ | $120,000 – $250,000+ |

The full-stack question: app + backend pricing
Most apps need a backend — a server that stores data, handles authentication, processes payments, and serves the API that the app talks to. Some pricing guides quote app cost alone, which is misleading. The backend is typically 40-60% of the total project cost.
Backend-only pricing (Node.js, 2026)
| Scope | Price range | What you get |
|---|---|---|
| Foundation (auth + 2-3 modules, ~20 endpoints) | $4,000 – $10,000 | Basic API, JWT auth, database, validation, error handling |
| Standard (5-7 modules, ~40 endpoints) | $8,000 – $18,000 | Domain services, event system, payment integration, API docs |
| Professional (8+ modules, ~60 endpoints, real-time) | $14,000 – $30,000 | WebSocket, full test suite, multiple integrations, transaction management |
Complete product bundles (Flutter app + Node.js backend)
| Package | App scope | Backend scope | Combined range | Delivery |
|---|---|---|---|---|
| Lean MVP | 3-5 features, basic architecture | Auth + 2-3 modules | $9,000 – $20,000 | 5-6 weeks |
| Production | 7-10 features, Clean Architecture, offline mode | 5-7 modules, payments, events | $22,000 – $45,000 | 10-14 weeks |
| Full Product | 10-14 features, offline-first, integration tests | 8+ modules, real-time, full test suite | $35,000 – $65,000 | 14-20 weeks |
These ranges assume Eastern European / specialist pricing. Multiply by 2-3x for US/Western European agency equivalents.
Hidden costs most guides don't mention
The app build is not the total cost. Budget for these:
| Hidden cost | Range | When it hits |
|---|---|---|
| App Store fees | $99/year (Apple) + $25 one-time (Google) | Before launch |
| Server hosting | $20–$200/month (basic) to $500–$5,000/month (scaled) | Monthly, forever |
| SSL certificate | Free (Let's Encrypt) to $300/year (EV) | Annual |
| Third-party services | $0–$500/month (push notifications, analytics, maps, payments) | Monthly |
| Maintenance & updates | 15-25% of original build cost per year | Annual |
| OS update compatibility | $2,000–$10,000 per major OS update | 1-2x per year |
| Feature additions | Varies — but architecture quality determines cost | Ongoing |
The maintenance line is critical. A $30,000 app with poor architecture costs $7,500-$15,000/year in maintenance. A $40,000 app with clean architecture costs $6,000-$10,000/year. By year three, the "cheaper" app has cost more in total.
How to read a proposal
When an agency or freelancer sends you a quote, check for these:
| Red flag | What it means |
|---|---|
| No mention of architecture | They're building without structure — fast now, expensive later |
| No mention of testing | Bugs will be found by your users, not by the development process |
| Fixed price with vague scope | The scope will creep, the quality will drop, or the price will change |
| No post-delivery support | They know you'll need help and they don't want to provide it |
| "We use AI to write 80% of the code" | In 2026, AI-assisted development is standard. But AI code without human architecture is fast spaghetti |
| Green flag | What it means |
|---|---|
| Paid discovery phase (1-2 weeks, $1,000-$3,000) | They want to understand before they build |
| Architecture explicitly named and explained | They've thought about the foundation, not just the screens |
| Test strategy included | They plan to catch bugs before you do |
| Post-delivery support period stated | They stand behind their work |
| Clear scope document before development starts | They're managing expectations, not guessing |
The AI factor: how AI tooling affects prices in 2026
GoodFirms' 2026 survey found that 91% of software development companies now use AI tools to reduce costs. 61% of companies report 10-25% budget reductions from AI-assisted development.
What this means for you:
- Development is genuinely faster. Code generation, automated testing, documentation — AI handles repetitive tasks that used to take hours.
- But architecture decisions haven't been automated. AI can write code. It cannot decide how to organize code for long-term maintainability. The human architect is more important than ever — the AI makes them faster, not replaceable.
- Prices haven't dropped proportionally. Developer rates haven't decreased; the same hours produce more output. You get more app for the same money, rather than the same app for less money.
- Quality variance is increasing. AI-assisted bad developers produce bad code faster. AI-assisted good developers produce good code faster. The gap between cheap and quality builds is widening, not narrowing.
Summary: what to budget
| Your situation | Recommended budget | Architecture | Timeline |
|---|---|---|---|
| Testing an idea | $5,000 – $15,000 | Basic/MVP | 1-3 months |
| Launching a first product | $15,000 – $30,000 | Clean Architecture | 3-5 months |
| Building your core business app | $30,000 – $60,000 | Clean Architecture / DDD | 4-8 months |
| Building a platform with backend infrastructure | $60,000 – $150,000 | DDD + infrastructure | 6-12 months |
| Enterprise with compliance and scale requirements | $150,000+ | Full stack | 9-18+ months |
The right budget is the one that matches your business reality. Spending $5,000 on an app that needs to handle $100,000/month in transactions is a mistake. Spending $50,000 on an app that might not find users is also a mistake.
Start with the question: "What would it cost my business if this app failed?" If the answer is "I'd be annoyed," build cheap and iterate. If the answer is "I'd lose customers, revenue, or compliance standing," invest in architecture. The foundation you can't see determines the building's lifespan.
