Frequently Asked Questions

What is the cost of iPhone app development?

iOS development firms price their services differently. Some will charge a per-hour rate that can range from $20 to $40 per hour, or a per-project rate that can start at $40,000 to $60,000 for simple apps. Complex apps can go up to $300,000 per project.

The app’s complexity is the primary deciding factor for the price, which is why most firms will require a project brief or a discovery call before providing a quote estimate. Additionally, the cost can be influenced by factors like the app's platform compatibility, integration with backend systems, and any specialized requirements.

The app development cost often includes the initial development and ongoing maintenance, updates, and potential future enhancements. It's crucial to thoroughly discuss your project requirements with potential development companies to get accurate cost estimates tailored to your specific needs.

What language is used for iPhone app development?

Apple specifically built a programming language called Swift for new iOS app developments. Legacy projects still use the Objective-C language, but most new apps have migrated to the recommended coding language.

Why should I develop apps for iOS?

According to Statista, there are over 1.6 million apps on iOS, making around 21.5 billion USD. This shows that iOS has a broad and engaged user base that can provide higher revenue potential. Building useful iOS apps will not only increase your brand relevance but will also bring in extra revenue.
