This guide breaks down what you need to know, shares the latest data, and highlights why companies like Stanga1 are trusted by businesses worldwide.
Why iPhone App Development Matters in 2025
The iOS market is booming. In the United States, iOS holds about 59.2% of the smartphone market share, making it the top choice for high-spending users. Globally, iOS users are responsible for 67% of all app revenue, even though Android has more users worldwide. If you want your app to reach users who spend more and expect premium experiences, iOS is the way to go.
What Makes a Great iPhone App Development Company?
Choosing the right partner means looking beyond flashy portfolios. Here’s what to check:
- Experience: Years in business and a number of projects delivered.
- Technical Skills: Mastery of Swift, Objective-C, Xcode, and Apple’s latest frameworks.

- Industry Focus: Experience in your business area, whether it’s healthcare, retail, fintech, or something else.

How Much Does iPhone App Development Cost in 2025?
Building an iPhone app is an investment, not just an expense. Here’s what you need to know:
- Average Cost: Simple apps start around $25,000. More complex solutions (think e-commerce, fintech, or social platforms) can reach $100,000 or more.
- Why the Price? You’re paying for premium design, security, and a smooth user experience. iOS users spend more—$12.77 per app on average—so your potential ROI is higher.
