What we bring

Two platforms, one momentum.

We write your application once and ship it on iOS and on Android. One team, one schedule, the same standard as native.

One codebase. Two apps.

Screens, journeys, rules: written once, running on iOS and on Android. What is decided for one holds for the other — nothing is duplicated, nothing drifts apart.

iOS and Android, the same day.

Every release lands on both stores at once. Your users move forward together.

Native, when it's needed.

Camera, Bluetooth, payments: where the device demands it, we write a native module. Occasional, targeted.

Releases that ship without friction.

Tests, build, store submission: the chain is automated. A fix never stays stuck on someone's machine.

True to each platform.

A shared base doesn't mean a generic app: every screen respects the habits of iOS and of Android.

Behind the scenes

What sits behind the screen.

Two apps, a single build. Here is how one codebase becomes a product on each platform.

  1. What the user touches

    A single design, rendered with each platform's native components.

    • React Native

  2. What is written once

    Screens, journeys, business rules: one TypeScript codebase, for iOS and for Android.

    • TypeScript
    • Expo

  3. What talks to the device

    When a feature needs the hardware, we drop down to native — only where it is useful.

    • Swift
    • Kotlin

  4. What builds and publishes

    An automated chain that tests, builds and sends both apps to the stores.

    • EAS
    • App Store · Play
Deliverables

What you get

  • Shared iOS / Android architecture

    A single codebase, structured so that both apps always move forward together.

  • An interface true to both platforms

    A shared design, adjusted where iOS and Android each have their own habits.

  • Sync and offline mode

    The app stays usable without a network, and catches up as soon as the connection returns.

  • Build and release pipeline

    Building and submitting to the stores are automated: a new version ships in a few steps.

  • Ongoing fixes and improvements

    An improvement is developed once and reaches both platforms.

Stack & technologies
  • React Native
  • Expo
  • TypeScript
  • Native modules
  • EAS

Indicative — the final stack is chosen to fit your project.

The right fit

Is this the right approach for you?

We don't sell the same answer to everyone. Here is when this approach is the right one — and when another will serve you better.

It's the right approach if…

  • You are launching iOS and Android at the same time.
  • You want to put a first version in your users' hands, then evolve it quickly.
  • Your product is built on accounts, content, forms and exchanges.
  • You care that both platforms move at the same pace.

Look instead at…

Unsure between two approaches? We settle it together, at the framing stage.
