Quick Summary
Mobile app development costs vary dramatically by complexity, platform, and features. Simple apps with basic functionality cost $40,000–$80,000. Medium-complexity apps with custom UI and integrations cost $80,000–$150,000. Complex apps with advanced features (AI, AR, real-time sync) exceed $200,000. Cross-platform development (React Native/Flutter) costs 30-40% less than building separate native iOS and Android apps.

Factors Affecting Cost
Platform Choice: Native vs Cross-Platform
High ImpactNative iOS + Android separately: $120,000–$400,000. Cross-platform (React Native/Flutter): $80,000–$250,000. Web app wrapper (cheapest): $40,000–$100,000 but limited features.
Backend Requirements
High ImpactFirebase (managed backend): +$10,000–$30,000. Custom backend with complex logic: +$40,000–$100,000. Real-time features (chat, live updates): +$20,000–$60,000.
Authentication & Security
Medium ImpactBasic email/password: $3,000–$8,000. Social logins (Google, Apple, Facebook): +$2,000 each. Biometric authentication: +$5,000–$10,000. Enterprise SSO: +$15,000–$30,000.
Payment Integration
Medium ImpactSimple checkout with Stripe/PayPal: $5,000–$12,000. Subscription billing with trials: +$8,000–$15,000. Multi-currency and complex pricing: +$12,000–$25,000.
Device Hardware Integration
High ImpactCamera, GPS, Bluetooth, NFC, sensors. Each hardware feature adds $3,000–$15,000. AR features: +$30,000–$80,000. IoT device integration: +$25,000–$60,000.
Offline Functionality
Medium ImpactFull offline mode with sync adds 20-30% to development time. Data caching strategy, conflict resolution, and background sync required.
Pricing Models
Native Development (iOS + Android)
Separate codebases for iOS (Swift) and Android (Kotlin). Best performance and native feel.
Apps requiring maximum performance or platform-specific features
Cross-Platform (React Native/Flutter)
Single codebase for both iOS and Android. 60-70% code reuse.
Most business apps, MVPs, apps without heavy hardware needs
Hybrid (Ionic/Cordova)
Web app wrapped in native container. Cheapest but performance limitations.
Simple apps, content-focused apps, tight budgets
Progressive Web App (PWA)
Advanced web app with app-like features. No app store required.
Apps not requiring app store presence or native features
Hourly / Time & Materials (Codexty)
Pay for actual hours worked. Flexible for any app scope.
Evolving requirements, MVPs, or phased mobile development
