Mobile app development for iOS and Android

Native iOS and Android apps, or one React Native codebase for both, designed for real-world use and built to ship to the App Store and Google Play.

Mobile app development with DevQuester

Mobile users expect apps to feel instant, work on poor connections and respect their battery and privacy. Getting there takes the right technical approach for your product, plus a solid backend behind it.

Our mobile app development team helps you choose between native development and a cross-platform React Native build based on your performance needs, budget and timeline. We then design, build and launch the app, including the API, authentication, notifications and store release process.

Who this service is for

  • Startups launching a mobile-first product
  • Businesses extending a web platform with a companion app
  • Field teams that need reliable mobile tools, including offline use
  • Companies replacing an outdated or unreliable app

Mobile App Development FAQs

Should I build a native app or use React Native?

Choose native when you need maximum performance, deep device features or a platform-specific experience. React Native is usually better when you want to launch on both platforms faster and with a shared codebase. We will recommend one after understanding your product.

How long does it take to build a mobile app?

A focused first version typically takes 8 to 16 weeks depending on features, platforms and backend complexity.

Do you publish the app to the App Store and Google Play?

Yes. We prepare builds, store listings and submissions, and handle review feedback. Developer accounts remain in your name.

Can you build the backend for the app too?

Yes. As a full stack team we build the API, database, authentication and admin tools that power your app.
