Native custom iOS Android Mobile Application Development
Functional Specifications
For any development project, it is essential to have precise specifications to ensure good consistency between your needs and the implementation of your application.
Mobile UI/UX Design
Each platform has its own guidelines. We follow Apple's Human Interface Guidelines and Google's Material Design to offer a native and intuitive experience.
Native iOS Development — Swift
Our iOS applications are developed in Swift, Apple's native language. This guarantees optimal performance, perfect integration, and full access to all iOS APIs.


Native Android Development — Kotlin
Our Android applications are developed in Kotlin, Google's official language, for modern, high-performance, and maintainable applications.
Testing on Real Devices
All our developments are tested on physical iOS and Android devices to guarantee perfect behavior under real-world conditions.
App Store & Play Store Publishing
We manage submission and publication on the Apple App Store and Google Play Store, including listing optimization (ASO) to maximize visibility.
Why choose native?
Native applications (Swift for iOS, Kotlin for Android) directly access operating system APIs. There is no intermediate abstraction layer, resulting in significantly superior performance.
16 years of experience in iPhone / iPad / iOS development and two attendances at WWDC in San Francisco make ECASTE a team of Apple iOS SDK experts. You can find some of our applications directly on the App Store by searching for the keyword "ecaste".
We can also come to your company to help with your development, whether reinforcing your teams or training your developers on the iOS platform.
