Develop mobile apps for iOS and Android

There are no longer apps available first on iPhone and then on Android or vice versa. Multiplatform technologies abolish this restriction and become essential.

Flutter: simple, efficient, open source, with a dynamic community

Structure An open-source UI developed by Google, Flutter challenges native technologies like Kotlin (Android) or Swift (iOS).

Flutter is capable of sharing 90% or even all of the code to generate native applications for iOSAndroid, websites and desktop applications for macOS, Windows and Linux, with performance very close to that of native languages ​​(app logic, modern and fluid UI).

It is easy to integrate the specificities of each operating system into Flutter and customer experience best practices are respected for each.

Finally, Flutter has a large developer community. More than 6 million developers have published more than 1.1 million applications in 2023. Flutter is notably among the top three contributing OpenSource projects on GitHub3 — a status that allows the technology to live on, be easily accessed and used (thanks to a modern system and fluid set of tools, such as hot reloading). Furthermore, Google has solid expertise for the rapid integration of services (Firebase, Analytics, etc.) in documentation and change management.

Technology like Flutter saves 30% of development and maintenance time compared to developing two native apps. Only one technology is needed to deploy on 2 targets, which mobilizes only a single development team: production is more efficient, faster and simpler.

Unity, the performance advantage for 3D and VR

Unity, a technology presented in 2005 at the Apple Worldwide Developers Conference, quickly established itself for interactive 3D applications, in virtual reality or augmented realitythat require specific technology, versatility and performance.

Also cross-platform, Unity is one of the favorite choices of game developers. It brings together a large and very collaborative community around itself: a large number of learning resources and support platforms are available to support both beginners and experts. Unity is particularly suited to “serious gaming” type applications.

For a more “classic” 2D application, it is better to resort to native or multiplatform technology because Unity involves more complexities, longer development times, as well as skills that are rarer on the market, but you must not forget to think in the long term: a The application must be active, patched and updated regularly.

Maintain applications developed for iOS and Android or develop them with cross-platform technology?

The question arises when it comes to updating old applications. Sometimes native code audit highlights many issues:

  • The app Android uses obsolete language: an update is expected
  • An architectural issue is detected: application maintenance is complex
  • The behavior of the two applications is not equivalent: they do not integrate the same functionalities

A code overhaul is possible, but it runs the risk of being costly in the long run. To enable better maintenance and also reduce costs, a complete review of the application with cross-platform technology should be considered.

For example, if the bluetooth is the critical functionality of the application, a PoC (Proof of Concept) can be developed in Flutter to ensure that performance is at least preserved.

Flutter can make the user experience equivalent between the two platforms iOS and Android, solve implementation problems of the native Android version, and stabilize the connection.
