React Native app development costs vary based on complexity, features, and timeline. A simple app might cost less, while complex apps with advanced features require larger investments. However, React Native typically saves 30-50% compared to building separate native iOS and Android apps. We provide detailed, transparent estimates after understanding your requirements in our free consultation.

Simple APIs with basic CRUD operations can be completed in 2-4 weeks. More complex APIs with multiple integrations, advanced authentication, and extensive documentation typically take 6-12 weeks. We provide detailed timelines during our free architecture consultation.

REST APIs use fixed endpoints that return predefined data structures — great for simple, cacheable operations. GraphQL APIs let clients request exactly the data they need in a single request — ideal for complex data relationships and mobile apps where bandwidth matters. We help you choose the right approach for your use case.

We implement multiple security layers: OAuth 2.0 or JWT for authentication, role-based access control, HTTPS/TLS encryption, input validation, rate limiting, and API key management. For sensitive industries, we follow SOC 2, HIPAA, or PCI-DSS compliance requirements as needed.
