A Mobile Agency to Turn Your Digital Ideas into Reality
At Mojjoo, we transform your needs into smart and scalable mobile applications. As an agency specializing in mobile app creation, we develop 100% personalized solutions designed to provide an optimal user experience across all platforms, both iOS and Android.
Our approach combines UX/UI design, technical performance, data security, and scalability. Whether you’re a startup, an SME, or a large corporation, we guide you from the initial idea all the way to launching your application.
Hybrid Apps: A Fast and Cost-Effective Solution
Do you want an app available quickly on both iOS and Android? We create hybrid apps from a single source code, which significantly reduces development costs and timelines.
We use high-performing frameworks like Flutter, React Native, Ionic, or Angular, paired with a robust backend (Laravel, Symfony, Firebase, NestJS…). The result: smooth, modern interfaces ready to evolve.
Native Apps: Maximum Performance and Custom Experience
For projects requiring high performance, Mojjoo develops native apps designed specifically for each operating system.
- iOS: development in Swift
- Android: development in Kotlin
- Back-end: technologies like Laravel, Node.js, Spring Boot, or Symfony
The native approach allows us to leverage the technical capabilities of smartphones (sensor access, fluid animations, advanced security).

What is a custom mobile app?
A custom mobile app is a solution developed specifically to meet a company’s needs and goals. It integrates a personalized design, specific features, and optimized compatibility with iOS and Android systems.
What is the difference between a native app and a hybrid app?
A native app is developed for a single system (iOS or Android), offering maximum performance. A hybrid app works on both platforms from the same code base, which helps reduce development time and costs.
How long does it take to create a mobile app?
The duration varies depending on the project’s complexity. On average, it takes between 8 and 24 weeks, including analysis, UX/UI design, development, testing, and publication.
What languages and frameworks do you use to develop a mobile app?
We use Swift (iOS), Kotlin (Android), Flutter, and React Native for mobile development. On the backend, we work with Laravel, Symfony, NestJS, Node.js, and Firebase.
Do you offer support after the app is published?
Yes. We provide a maintenance service that includes updates, performance improvements, bug fixes, and adding new features based on your evolving needs.
