Mobile apps generate 3x higher engagement than mobile websites. They enable push notifications, offline access, device feature integration, and personalized experiences that increase customer loyalty and lifetime value.
Simple apps cost $15,000-$40,000, medium-complexity apps range from $40,000-$100,000, and feature-rich enterprise apps start at $100,000-$300,000+. Cross-platform development saves 30-40% versus building separate native apps.
Select agencies with published app store successes, platform expertise (iOS, Android, Flutter), strong UI/UX capabilities, and robust testing processes. Check portfolio relevance, post-launch support, and client satisfaction scores.
Native apps (Swift, Kotlin) offer best performance and platform-specific features. Cross-platform (Flutter, React Native) enables faster development with shared code. Choose native for complex apps; cross-platform for faster time-to-market.
Simple apps take 2-3 months, medium-complexity apps require 4-6 months, and enterprise apps need 6-12+ months. Timeline depends on feature scope, platform count, backend complexity, and testing requirements.
