The cost of mobile app development in 2025 will vary based on factors like app complexity, features, design, and platform choice (iOS, Android, or both). Simple apps with basic features may start around $20,000, while more complex apps with advanced functionalities, integrations, and custom designs can range from $50,000 to $200,000 or more. Other considerations include developer rates, project timelines, and post-launch support. With technology rapidly evolving, businesses may also need to invest in new trends like AI, AR, or blockchain, which can influence overall costs. Careful planning is essential to optimize your app development budget.
