Native mobile build work

Build a native iOS and Android app that can actually ship.

Swift, Kotlin, backend APIs, offline sync, analytics, release pipelines, monitoring, and handover. We build native mobile apps for teams that need speed, device integration, reliability, and long-term ownership. No Flutter, no React Native, no throwaway prototype that has to be rebuilt after launch.

What we usually hear when teams come to us

You need native performance, not a shortcut

Some apps need real platform work: camera, Bluetooth, location, offline sync, background tasks, push, payments, device APIs, accessibility, and reliable releases. We design the iOS and Android architecture around those constraints from day one.

The MVP still has to survive production

A mobile MVP that crashes, loses offline data, or cannot pass store review is not cheaper. We ship production code, crash reporting, analytics, end-to-end flows, release notes, and handover from the first usable version.

Your backend and app need to move together

Native apps rarely live alone. We build the API contracts, auth, notifications, admin tools, analytics events, and deployment path alongside the mobile work so the app is usable by real teams, not just a demo on one device.

You want ownership after launch

Source code, release process, architecture notes, analytics plan, runbooks, and a clean handover are part of the engagement. Your team can keep shipping after we leave, or keep us around only where it makes sense.

How a typical engagement actually runs

Week 1 to 2: Product and technical spec

We map core flows, device requirements, API contracts, auth, analytics, offline needs, release risks, and store constraints. You get a practical build plan before the main implementation starts.

Week 3 to 10: Native build, weekly demos

Swift and Kotlin implementation, backend integration, test builds, QA loops, crash reporting, and working demos on real flows every week. The app gets closer to release every sprint.

Week 10 to 12: Release and handover

Store submission support, release notes, monitoring, analytics review, runbooks, source code, and technical handover. You own the app, the backend work, and the operating knowledge.

Things people usually ask

Not for this offer. This landing page is for native iOS and Android work: Swift or SwiftUI on iOS, Kotlin or Jetpack Compose on Android, plus the backend and release plumbing needed to ship properly.

Yes. Native apps usually need APIs, auth, notifications, file handling, admin views, analytics events, and deployment work. We handle that as part of the build instead of leaving mobile engineers blocked on backend gaps.

Yes. We can build the first production version, pair with your engineers, or take over a slice of the native app while your team handles product and backend. The handover is written into the plan.

That is common. We can launch iOS first, Android first, or both together. The architecture still keeps the second platform in mind so you do not pay for preventable rewrites later.

You. Source code, API contracts, release process, documentation, analytics plan, and runbooks transfer to you. We do not keep proprietary plumbing between you and your app.

Crash reporting, analytics, QA builds, device checks, release gates, and automated tests where they matter. We focus on the failures that hurt real users: login, sync, checkout, notifications, permissions, and core workflows.

Most native mobile builds are 8 to 12 weeks with a senior mobile engineer, backend support, and design/front-end support when needed. We start with a short technical spec so the build has a clear release path.
