Build

Mobile development

iOS and Android applications developed once, published on both stores and maintained for the long term.

01Approach

A successful mobile application is not decided on launch day, but in the months that follow: stability, operating system updates, user feedback. iones designs and develops cross-platform applications built to last, from a single codebase for iOS and Android.
This technical choice cuts development and maintenance costs without sacrificing the experience: near-native performance, access to phone features (camera, geolocation, notifications, biometrics) and an interface faithful to your design.
We take charge of the whole chain: architecture, development, the associated API and back office, tests on real devices, publication on the App Store and Google Play, then follow-up after launch.

Scope of work

  • Cross-platform iOS and Android applications
  • Business and field applications
  • E-commerce and loyalty applications
  • Associated API and back office
  • Publication to the stores
  • Maintenance and enhancements

02Expertise

Consumer applications

E-commerce, loyalty, services, content: smooth, polished applications designed to be used every day and to earn good ratings on the stores.
  • User journeys and onboarding
  • Push notifications and engagement
  • Payment and customer account

Business applications

Tools for field teams, logistics or sales staff, connected to your information system and usable even without a network.
  • Offline mode and synchronisation
  • Scanning, photo, signature, geolocation
  • Secure connection to your IS

Takeover and further development

An existing application to develop further, a native codebase to unify or a version blocked by an iOS or Android update: we take over what exists and put it back on track.
  • Code and dependency audit
  • Migration to Flutter or .NET MAUI
  • Store compliance

03Technical stack

One codebase, two platforms

Two proven cross-platform frameworks, chosen according to your technical context and your teams’ skills.

Mobile frameworks

iOS and Android from a single codebase.

  • Flutter
  • Dart
  • .NET MAUI
  • C#

API & back office

The server and the administration tool for the application.

  • Node.js
  • Symfony
  • Laravel
  • REST API

Mobile services

The standard building blocks of a modern application.

  • Push notifications
  • Authentication
  • In-app payment
  • Analytics

Testing & publication

From acceptance testing to going live on the stores.

  • Tests on real devices
  • Mobile CI/CD
  • App Store
  • Google Play

04Why iones

What you gain with iones

A team that delivers the application, but also everything around it.

One development for both

iOS and Android from a shared codebase: one budget, one schedule and one team instead of two.

Carefully tuned performance

Start-up time, screen smoothness, consumption: we measure and optimise on real devices.

Built-in security

Data encryption, strong authentication and mobile security best practices from the design stage.

Maintainable over time

Documented code, automated tests and tracking of operating system versions so that the application stays up to date.
