A full-featured product with AI integration or game mechanics can take 6–12 months. LIAWEB uses agile sprints to deliver working features iteratively throughout development.
The best framework depends on your needs. Flutter is ideal for most cross-platform apps — it offers near-native performance, a single codebase for iOS and Android, and excellent UI flexibility. React Native is great for JavaScript teams. For maximum performance, native Swift (iOS) or Kotlin (Android) is recommended. LIAWEB evaluates each project individually and recommends the best technology for your goals.
Cross-platform (Flutter or React Native) is recommended for most startups and businesses because it reduces development time and cost by up to 40% while sharing a single codebase. Native development (Swift for iOS, Kotlin for Android) is best when you need maximum performance, complex hardware access, or platform-specific features. LIAWEB can advise on the right approach during your free consultation.
