iOS App Development in the USA

iPhone users tend to spend more inside apps and expect things to look and feel right. A clumsy iOS app gets deleted quickly, so the details matter.

  • Sign in with Apple, email or phone
  • Apple Pay and in-app purchases
  • Face ID and Touch ID
  • HealthKit and Apple Watch data

What changes for the United States

In the US, iPhone users are a large and high-spending audience, so App Store quality and reviews matter a lot.

For businesses in the United States, we usually add Stripe, Apple Pay, Google Pay, PayPal and Square as payment options, and we plan for App Store and Google Play privacy labels, state privacy laws such as California's, and HIPAA planning for health apps.

We build iOS apps in Swift and SwiftUI and follow Apple's design guidelines, so your app feels familiar from the first tap. We also handle the App Store review process, which can be strict for first-time publishers.

What it costs

Prices are determined by the complexity of your app and the time involved. Every app is different, so we quote each project on its own.

Post your project with a short description and we will send a clear, no-obligation quote, usually within one working day.

What affects the price

  • Features such as payments, chat, maps or live tracking
  • Android, iPhone or both
  • How detailed the design is
  • Connections to other software, such as your CRM or Google Sheets

Questions people ask

Do I need a Mac or Apple account?

You need an Apple Developer account in your business name. It costs a yearly fee paid to Apple. We do the rest on our own machines.

Why do apps get rejected by Apple?

Common reasons are missing privacy details, broken login for reviewers, or features that feel unfinished. We check these before submitting to avoid delays.

Can you also build the Android version?

Yes. If you need both, we will talk you through whether two native apps or one cross-platform app makes more sense for your budget.
