The cost of hiring an app development agency depends on factors like app complexity, features, platform (iOS, Android, or both), and location of the agency.

• Basic apps (simple UI, minimal features) – $10,000 to $50,000
• Medium complexity apps (custom UI, backend, API integration) – $50,000 to $150,000
• Complex apps (AI, real-time features, advanced security) – $150,000+

Freelancers or offshore agencies may charge less, while top-tier agencies in the US, UK, or Europe charge higher rates. Additional costs include maintenance, updates, and marketing.
