iOS and Android Apps, From Idea to App Store

Native iOS and Android apps or one cross-platform codebase, with the backend, APIs, AI features and store launch handled by the same team that runs your website.

A good app starts with a clear scope. We help you decide what the first version really needs, which platform approach fits (native Swift and Kotlin, or React Native and Flutter for both stores from one codebase) and what it will cost, before anyone writes code.

Because we also build websites, APIs and AI systems, your app does not live on an island. It can share accounts, products and content with your WordPress or WooCommerce site, use a secure backend we build and maintain, and include AI features such as in-app chat and smart search. We handle App Store and Google Play submission, then keep the app current as iOS and Android change.

Native or cross-platform, honestly

We recommend Swift, Kotlin, React Native or Flutter based on your users, budget and roadmap, not on what is easiest for us.

Backend and website in one place

APIs, databases, push notifications and admin panels are built alongside the app, and can connect to the website you already run.

AI features done properly

In-app chat, smart search and recommendations built on your own data, with API keys kept on the server and costs under control.

FAQ

Mobile Apps: Questions Answered

Should I build native or cross-platform?

Native apps (Swift for iOS, Kotlin for Android) give the deepest platform integration and performance. Cross-platform apps (React Native or Flutter) ship to both stores from one codebase, which usually lowers cost and speeds up updates. We recommend one after understanding your features, audience and budget.

Who owns the app and the developer accounts?

You do. The App Store and Google Play developer accounts are registered in your business name, and you own the source code, designs and backend once the project is paid for.

How much does an app cost?

Cost depends on the number of screens, user accounts, payments, integrations, backend needs and whether you need one platform or two. Send a brief and you get a fixed-price estimate with a clear scope before any work starts.

Do you maintain apps after launch?

Yes. iOS and Android change every year, and store policies change with them. Monthly maintenance covers OS and SDK updates, crash monitoring, bug fixes and small features.
