Five complexity tiers with real market ranges. iOS vs Android, React Native vs Flutter vs native, and the four hidden cost drivers that move the bill 4x.
A clean mobile app MVP with 5-10 screens on one platform costs around $25,000 to $50,000 from a competent agency. A complex native iOS + Android app with real-time features, payments, and a custom backend routinely runs $120,000 to $250,000. Enterprise apps with ERP integration, multi-role access, and analytics push past $400,000. The cost is driven by feature complexity and platform count, not by which framework you pick.
Numbers are market ranges across US + UK + India agencies in 2026. Cheaper offshore quotes exist; quality varies. Above $250K, the senior engineering bench matters more than the hourly rate.
| tier | scope | timeline | market range |
|---|---|---|---|
| Simple MVP | 5-10 screens, single platform, Firebase backend | 8-12 weeks | $25K-$50K |
| Cross-platform mid | React Native / Flutter, 15-25 screens, custom backend | 12-20 weeks | $50K-$120K |
| Complex native | Native iOS + Android, payments, real-time, push | 20-32 weeks | $120K-$250K |
| Enterprise | Multi-role, ERP / CRM, analytics, admin dashboard | 26-40 weeks | $250K-$500K |
| Hardware companion | BLE / OTA / HealthKit / device pairing | 24-40 weeks | $200K-$500K+ |

| approach | cost vs single-platform native | best for |
|---|---|---|
| Native iOS only (Swift) | 1.0x baseline | iOS-first audiences (US consumer, fitness, fintech) |
| Native Android only (Kotlin) | 1.0x baseline | Android-first markets (India, SEA, LATAM, hardware) |
| Native iOS + Android (both) | 1.7-1.9x | Performance-critical apps, hardware integration, gaming |
| React Native (one team, both stores) | 1.1-1.3x | Content + commerce, Web team reuse, fast iteration |
| Flutter (one team, both stores) | 1.1-1.3x | Brand-first design control, custom UI, motion-heavy |
| Progressive Web App (PWA) | 0.4-0.6x | Content apps, no app-store install required |
Cross-platform is 30-40% cheaper than dual-native because one team ships both stores. The trade is platform-API depth: HealthKit, ARKit, BLE, deep iOS / Android integrations work better natively. See our native vs hybrid breakdown for the full decision tree.
Firebase + 3 Cloud Functions = $5K-$15K of backend work. Custom Node.js / Python API with database modeling, auth, role permissions = $25K-$80K. Real-time (chat, presence, sync) via WebSockets or Supabase realtime adds another $15K-$40K.
Stripe payments: 20-40 hours. Apple Pay + Google Pay: 30-60 hours each. Plaid bank links: 40-80 hours. Shopify Storefront API: 60-120 hours. Each non-trivial integration adds $4K-$25K.
Stock UI components: 40-80 design hours. Custom design system with brand-specific motion: 120-300 hours. Lottie animations, custom transitions, micro-interactions add $8K-$30K. The visual quality of the top 10% of App Store apps requires design + motion budget that doubles cheaper builds.
HIPAA-compliant health app: $30K-$100K of additional engineering + audit. PCI-DSS payments: $15K-$40K. SOC 2 Type II readiness: $40K-$120K (one-time) plus annual audits. HealthKit + Apple's privacy review adds 4-8 weeks of submission cycles.
| item | cost |
|---|---|
| Apple Developer Program | $99/year |
| Google Play Console | $25 one-time |
| Backend hosting (10K-100K MAU) | $200-$2,000/mo |
| Push notifications + analytics | $50-$500/mo |
| Crash reporting (Sentry / Firebase) | $0-$300/mo |
| Maintenance / iteration retainer | $3K-$15K/mo (typical) |
| App Store fees (in-app purchases) | 15-30% per transaction |
Year-one stack typically adds $4,000-$25,000 on top of the build. Apps that ship and then sit broken are the most expensive outcome — budget the maintenance retainer from day one.
A basic mobile app MVP costs $25,000 to $50,000 from a senior-led agency. That covers 5-10 screens, single platform (iOS or Android), Firebase or Supabase backend, basic authentication, and one or two integrations. Cheaper offshore quotes ($8K-$15K) exist but typically use junior teams; the resulting app often needs a full rebuild within 12 months. Budget 8-12 weeks for the MVP build plus 4-6 weeks of post-launch iteration.
Build cost is roughly equal — both ecosystems have mature SDKs and pricing parity for senior engineers. The differences are testing and design. iOS is cheaper to test (3-5 device configurations cover 90% of users); Android needs 8-15 device configurations for the same coverage. Android UI patterns (Material Design 3) and iOS UI patterns (Human Interface Guidelines) require separate design review even for cross-platform builds. Pick by audience: US consumer is iOS-heavy; emerging markets and hardware integrations are Android-heavy.
Cross-platform frameworks are 30-40% cheaper than dual-native development because one team ships both app stores. A React Native build that would cost $200K as iOS-only + $200K as Android-only ($400K total) usually lands at $230K-$280K. The trade is depth: HealthKit, BLE, ARKit, complex animations, and deep platform integrations work better natively. Most content + commerce apps run beautifully on React Native or Flutter. See our React Native and Flutter development service pages.
Enterprise mobile apps run $250,000 to $500,000 typically. The drivers: multi-role permissioning, ERP / CRM integration (Salesforce, SAP, Microsoft Dynamics), admin web dashboard, single sign-on (SAML / OIDC), and offline mode with conflict resolution. Add SOC 2 Type II readiness ($40K-$120K) for B2B SaaS apps. Healthcare apps add HIPAA compliance ($30K-$100K). Financial apps add PCI-DSS audit. Enterprise builds typically take 26-40 weeks of senior engineering effort.
Three reasons. First, scope: cheap quotes often skip backend work, design polish, real testing, and post-launch support. Second, team seniority: junior offshore engineers ($10-$25/hr) can deliver a working build but ship 3-5x more bugs than senior teams ($80-$200/hr) and the rework costs more than the difference. Third, code ownership: cheap quotes sometimes leave you on the developer's Apple ID or use closed builders that cannot be exported. The cheapest quote is rarely the lowest total cost. The right benchmark: senior teams ship faster and ship code you can maintain.
Budget 15-25% of the original build cost per year for ongoing maintenance and iteration. A $100K app should reserve $15K-$25K/year for OS updates (iOS 18, 19, 20 each require code changes), API deprecations, app-store policy compliance, security patches, and incremental feature work. Apps that skip maintenance break inside 18 months: Apple deprecates APIs, Google tightens privacy rules, third-party SDKs go end-of-life. Our mobile app development service includes a 6-month post-launch warranty plus optional retainer.
