Apps That Feel Native and Work Everywhere

One team for the app, the backend and the store release — so you get a working product, not just screens.

  • Feels Native. Because It Is.

    iOS gestures on iOS, Material on Android, 60fps throughout — no wrapped websites, no laggy hybrid feel.

  • One Build. Both Stores.

    React Native and Flutter reach iOS and Android from one codebase — roughly half the cost of building twice.

  • Works Offline

    Local caching, sync queues, push notifications and live updates keep the app working on any connection.

  • The Whole App, Not Just Screens

    API, auth, admin panel and CRM/ERP/payment integrations built as part of the same project.

  • We Handle the Stores

    App Store and Play Console submissions, review requirements and staged rollouts — on us.

  • AI Built In, Not Bolted On

    AI-assisted coding and testing for faster builds — plus smart search and personalization inside the app.

It depends on features, platforms and integrations. After a free consultation we cut scope to what proves the idea and agree a timeline and price before writing any code.

For most business apps, marketplaces and internal tools, cross-platform with React Native or Flutter gets you to both stores faster and for less. We recommend native Swift or Kotlin when the app relies on heavy graphics, advanced hardware access or brand-new platform features.

A typical first release takes around 14 weeks, from discovery and design to development, testing and store release. After discovery you get a clear timeline with milestones.

Yes. We prepare store listings, privacy manifests, data-safety declarations and age ratings, handle the review process and manage staged rollouts — so your app gets approved without surprises.

We can keep supporting your app with OS updates, crash monitoring, bug fixes, performance improvements and new features as your users and business grow.
