Android app development

Bring your product to Android users with an app built around their needs. Our London studio helps UK and international businesses plan a new Android app or extend an iOS product, using shared Swift development with Skip or a dedicated Kotlin implementation.

The right starting point

Reach your Android customers.

Give your customers or team a useful Android experience. We start with the journeys, device features and systems your app needs, then recommend a delivery approach around your product and future plans.

  • Launch a new Android app for your customers or team.
  • Bring an existing iOS product to Android users.
  • Redesign or extend an Android app with more capabilities.

Scope & delivery

Two ways to build for Android.

Both routes deliver an app with native Android interfaces. We choose the approach around your features, integrations and plans for both platforms, with Android testing and release preparation included in the agreed scope.

Shared Swift development with Skip

For products that suit a shared approach, reuse suitable Swift code and supported SwiftUI views across iOS and Android. Skip brings those views to native Android interfaces. We assess compatibility first and plan any Android-specific features or integrations alongside the shared work.

Dedicated Kotlin development

Build directly with Kotlin and Jetpack Compose when an Android-focused roadmap, existing Kotlin code or platform requirements favour a dedicated implementation. Shape the interface around Android users, with its own codebase and direct access to Android APIs.

Testing and Google Play preparation

Review the app on emulators and agreed physical devices. Test navigation, permissions, important journeys and failure states, then prepare the agreed release for Google Play submission. Accounts, store requirements and handover responsibilities are planned with you.

Working together

From the first conversation to release

  1. Define the Android experience

    Identify the users, core journeys, supported devices and features your release needs.

  2. Choose and check the approach

    Review the code, UI and integrations. For a shared approach, validate a representative journey and the important Android requirements before committing to the wider build.

  3. Design and build

    Review working updates as the shared Swift or dedicated Kotlin implementation takes shape, including platform-specific details.

  4. Test and prepare for release

    Check the agreed Android experience, prepare for submission and plan source access, accounts and the handover.

Planning the project

What affects cost and timeline?

Your Android quote follows the delivery approach and the work your app needs. Existing iOS code can provide a starting point, with Android requirements assessed separately:

  • The journeys, supported Android devices and OS versions.
  • Reusable Swift code, SwiftUI compatibility and any existing Kotlin work.
  • Authentication, data, payments and third-party SDK requirements.
  • Android-specific features, testing, Google Play preparation and handover.

Before we begin

Common questions

Which approach is right for our app?

A shared Swift approach can fit a product that needs both iOS and Android, where its UI, logic and dependencies work with Skip. A dedicated Kotlin app can fit an Android-focused product or existing Kotlin codebase. We review your requirements and validate the important integrations before recommending the route and agreeing the build scope.

Does Skip produce a native Android app?

Yes. Supported SwiftUI views are implemented using native Jetpack Compose interfaces on Android. Skip Lite translates Swift into Kotlin; Skip Fuse compiles Swift for Android and bridges to Android APIs. The choice between Skip and a dedicated Kotlin project is about code sharing, compatibility and maintenance, while both routes require Android testing.

Can you reuse our existing iOS app?

We first review its Swift code, SwiftUI components, Apple frameworks and third-party packages. Suitable parts can be shared with Skip, while unsupported UI or Apple-specific features need alternatives or Android-specific implementation. We check a representative journey and key integrations before committing to the shared approach; an iOS app does not automatically become an Android release.

How much will Android development cost?

Android development is scoped and quoted separately. The iOS prices in our cost guide do not include an Android release. We estimate your Android work after reviewing the features, delivery approach, reusable code, integrations and device testing. Your written quote confirms the price, VAT treatment, schedule and deliverables.

How will we work with your team?

Our studio works with contractors and collaborators. During project planning, we agree the people, roles, responsibilities and review stages around your chosen approach, so you know who is involved and how the work will progress.

What happens after the Android app launches?

We agree source-code access, licences, ownership and store account responsibilities before the build, alongside handover and any ongoing support. New Android versions, dependency updates and further features are considered in the maintenance or development scope you arrange with us.
