# Native mobile apps

The best of iOS and Android.

We write one app for iPhone, another for Android. Each made to measure.

What we bring

## An app that gets everything out of the device.

Native means writing the application in each platform's own language. The difference is felt from the first gesture: everything responds, everything is in its place, the whole device is available.

### At home on every device.

On iPhone it follows the conventions of iOS. On Android, those of Android. Your users keep their reflexes — navigation, gestures, settings — with nothing to relearn.

### Fluid, without thinking about it.

Scrolling, transitions, animations: motion follows the finger, at the display's own pace.

### The whole device, at your service.

Camera, location, biometrics, Bluetooth: direct access, no intermediary.

### There at the right moment.

Notifications, widgets, lock screen: your product also exists outside the app.

### Published, not just delivered.

Listings, screenshots, Apple and Google review: we take the app all the way to the stores, then follow every release.

Behind the scenes

## What sits behind the screen.

An app is more than a screen in a pocket. Four layers hold it up — we design all of them, on iOS and on Android.

1.  What the user touches

    ### 

    SwiftUI on iOS, Jetpack Compose on Android: the platform's own components, drawn for your product.

    -   SwiftUI
    -   Jetpack Compose

2.  What your product does

    ### 

    Journeys, rules, local data: what makes the application run, including offline.

    -   Swift
    -   Kotlin

3.  What the device allows

    ### 

    Camera, location, notifications, biometrics: the direct link to the hardware and the system.

    -   iOS APIs
    -   Android APIs

4.  What connects and distributes

    ### 

    The server that syncs the data, and the App Store and Google Play listings that distribute the app.

    -   API
    -   App Store · Play

Deliverables

## What you get

-   ### Dedicated iOS and Android design

    Two interfaces, each thought through for its platform, one identity: yours.

-   ### Swift / Kotlin development

    Each platform's native code, written to last and to follow the evolution of iOS and Android.

-   ### Sensor and notification integration

    Camera, location, biometrics, notifications: wired in cleanly, with permissions requested at the right moment.

-   ### Store preparation and release

    Listings, screenshots, compliance: we put the file together and see the review through to launch.

-   ### Version tracking and maintenance

    Every new version of iOS and Android is anticipated: the app stays up to date, and stable.

Stack & technologies

-   Swift
-   SwiftUI

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…

-   The experience is the heart of your product, not a side note.
-   Your app leans on the hardware: camera, Bluetooth, sensors, augmented reality.
-   You are aiming for daily use, where every detail of fluidity counts.
-   You want to follow what's new in iOS and Android as closely as possible.

### Look instead at…

-   [Cross-platform apps if you are launching iOS and Android at the same time, with a shared interface.](https://swift-up.com/en/savoir-faire/apps-cross-platform)

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

## We also build.

Same studio, same standards. Only the form changes.
