Mobile Applications

Mobile apps that fit the way people work, on the phones they already carry.

Why It Matters

A mobile app lives on a device you do not control. The operating system changes, the network drops, and the app stores decide when a release reaches users. A poor first release is hard to undo.

Many mobile projects fail in the same ways. The app copies a web page instead of using the device, it loses work when the signal drops, or it is never updated after launch. Users leave and the investment stops paying back.

What We Do

  • Apps built for each platform, using the device, its sensors and its security.

  • One codebase for both stores, with the platform details done properly.

  • Services, updates and store releases that keep the app working after launch.

  • The app keeps working without a signal and syncs when the connection returns.

What Changes for You

  1. The app fits a real task, opens quickly and asks only for the permissions it needs on the phones your users own.

  2. We keep it working with each new operating system and store rule, and updates reach users in small, tested releases.

  3. Field teams can save data without a signal, and the app syncs when the connection returns and resolves conflicts by agreed rules.

How the Work Runs

The app is proved on real devices before the full build. Each stage ends with something your users can try.

  1. Decide the Shape

    We agree the users, the tasks and the devices. You decide whether the app must be native or can share code across both stores.

  2. Prove the Flow

    We build a working flow and test it on real devices. You try it with users and approve the experience before the full build.

  3. Build

    We build the app and its services in short cycles. You provide test devices and access to the systems it needs, and you review each release.

  4. Release

    We prepare the store listings, signing and staged release. Your organisation holds the developer accounts, and you decide when to publish.

Team and Engagement Options

Choose a team that can stay through the store releases. The scope, devices and release owners are agreed before work starts.

  • A team that owns design, build and store releases. It stays with the app as operating systems change.

  • A team focused on one release or one set of screens. The scope and result are agreed before work starts.

  • Our mobile engineers join your team. They follow your code reviews, branch rules and release process.

Platforms and Technologies

We build on the cloud and tools that fit a mobile release. The app and its services run on AWS or Azure, the two cloud platforms we use. Swift and Kotlin are the native languages for Apple and Android devices, and SwiftUI and Jetpack Compose are their interface toolkits. React Native and Flutter share one codebase across both. Node.js runs the services behind the app, TypeScript is a programming language, and PostgreSQL stores data.

Naming a product does not mean a partnership with its vendor.

Questions

What buyers ask before they commission an app.

Should we build native or cross-platform?

Native apps in Swift and Kotlin use the device fully. React Native and Flutter share code across both stores and cost less to change. We recommend native when the app depends on the device, and shared code for most business apps.

Who owns the app store accounts?

Your organisation holds the developer accounts. We work under access you grant and can withdraw. Store listings, signing and review submissions are prepared with you.

Can the app work without a connection?

Yes, where the task allows it. We store the data each user needs on the device, encrypted, and queue changes until the connection returns. Agreed rules decide what happens when the same record changed in two places.

What shapes the effort an app needs?

The number of screens and roles, the devices, offline use and the systems it connects to. Store release work and keeping up with new operating system versions are ongoing costs. We agree the first app release before you commit.

Who supports the app after launch?

We watch crashes and usage, fix what the first users find and release updates. You can keep us for support or hand the app to your team. The handover includes the store accounts and signing keys.
