Customized mobile applications for iOS and Android

A Mobile app is software designed to run on a smartphone or a tablet. It offers a user experience specific and optimized for mobile screens. It can be downloaded from a App store like Google Play for Android or the App Store for iOS.

For businesses, these famous apps have established themselves as an essential asset. They make it possible to engage customers, improve brand visibility, increase sales and stand out from the competition. At Nubios, we fully understood The importance of mobile applications for your business. This is why we are committed to developing quality digital solutions that meet the specific needs of your target audience.

A native app is specifically developed for a single platform (Android or iOS). Its design can be done with programming languages specific for each platform (e.g. Java for Android, Swift for iOS). It offers the best performance and can use all the native functions of your smartphone (the camera, the fingerprint, the media...)

A web application (Web app or PWA) is a program directly accessible via a web browser. It is developed in HTML, CSS and JavaScript. Less expensive, it does not offer the same range of functionalities as a mobile application. Indeed, some specific developments may require more advanced technologies.

A hybrid application is a web application encapsulated in a native application. It is developed using a Framework like React Native or Flutter. Its main advantage lies in its compatibility with Apple and Android devices. Indeed, only one development is required for both operating systems.

The duration of development of a mobile application depends on many factors: the complexity of the application, the number of features, the platform (Android, iOS or both) and many other elements like graphic design and backend. On average, the development of a mobile application can take 2 to 6 months.


At Nubios, we understand that time is a determining factor for our customers. That is why we are committed to respect the agreed deadlines while guaranteeing the quality of our work.

We use agile development methodologies that allow us to quickly deliver functional versions of the application. In this way, continuous improvements are made based on Feedback from your users.

For information only, the development of a simple mobile application (e.g. internal tool, MVP or prototype) starts around €15,000.
For a more complete application, integrating an API, a custom interface and real-time functionalities, you have to count between €25,000 and €50,000.

The most ambitious projects — with IoT integration, back office, or custom user experience — may exceed 80,000€.
