The app development process: From idea to launch in 6 phases
From the first idea to the finished app in the store – the development of a mobile application is a complex undertaking.
A structured and transparent process is the key to success.
This article guides you through the six crucial phases of the app development process and shows you what happens in every step.
Phase 1: Discovery & Strategy

Everything starts with an idea. In the discovery phase, this idea is concreted and tested for its marketability.
Together with the App Agency, the targets are defined, the target group is analyzed and the core functions of the app are defined.
The result is a detailed concept and a specification that serves as a timetable for the entire project.
Phase 2: UI/UX Design
Short: In this phase, the app gets her face.
In this phase, the app gets her face. UX designers first create Wireframes (wire grid models) to plan the structure and user flow.
The visual design is then defined in the UI design. The result is a clickable prototype that already gives a realistic feeling for the finished app.
Phase 3: Development
Now the app is programmed. This phase is generally divided into agile sprints.
The backend (servers, databases, APIs) and the frontend (the visible user interface) are built in parallel.
Regular demo terminals ensure that you can track progress and give feedback early on.
Phase 4: Testing & Quality Assurance
Before the app goes to the users, it is checked for heart and kidneys.
A team of testers is looking for bugs (Bugs), checks the features on different devices and ensures that the app is stable and performant.
Phase 5: Launch
The app is submitted to the Apple App Store and Google Play Store for release.
The Agency supports you in creating store entries and complying with the respective policies.
Phase 6: Maintenance & Development
Short: After the launch, the work is not over.
After the launch, the work is not over. Operating system updates, vulnerabilities and user feedback require continuous maintenance and further development of the app.
A maintenance contract with the agency ensures the long-term success of your application.
