Mobile App Development in the USA
iPhone use is high in the US, so iOS quality cannot trail Android. A single cross-platform codebase lets both ship together, and our overnight build cycle means a review in your morning usually has changes by the next one.
We deliver iOS and Android apps, from a first version to production for companies in New York, Houston, Dallas and Chicago — remotely from our Karachi office, in your working hours, at a fixed written price.
Short answer
A2Z Global builds iOS and Android apps for US businesses as an offshore team — cross-platform from one Flutter or React Native codebase, with Stripe, Apple Pay and Google Pay, accessibility support, and store accounts in your company's name. We overlap with your morning for reviews, build overnight, and quote each project at a fixed price.
Key takeaways
- Cross-platform is the default for business apps; native is the exception you should be able to justify.
- The cost of an app is mostly the years after launch, where one codebase halves the work.
- App store accounts and signing keys must be in your company's name.
- Scope the first release around one journey a user completes, not a list of features.

What an app for the USA has to handle
The details that make mobile app development for the USA different from anywhere else — and that we plan for before the first screen is designed.
| What changes | In the USA |
|---|---|
| Language and layout | English. Spanish interfaces where your customers need them. |
| Payments inside the app | Stripe, PayPal, Square, Authorize.net, Apple Pay and Google Pay, Affirm and Klarna |
| Data and privacy | There is no single federal privacy law. State laws apply — California's CCPA/CPRA is the best known — alongside sector rules such as HIPAA for health data. Website accessibility is also a real legal exposure: businesses are sued under the ADA over inaccessible sites, so we build to WCAG. |
| Working hours | Pakistan is 9 to 10 hours ahead of US Eastern time, so we overlap with your morning for calls and build while you sleep — you wake up to progress rather than waiting on it. |
| Pricing | Priced per project. You get one fixed written quote after a discovery call. |

Mobile App Development in USA: common questions
Will the app pass App Store review?
We build to Apple's and Google's guidelines and handle privacy disclosures and submission. Rejections usually come from policy issues, which we check before submitting.
Is the app accessible?
It supports platform accessibility features — screen readers, dynamic text size and sufficient contrast.
Who owns the app and code?
You do — store accounts, signing keys and the full codebase are in your company's name.
