Our mobile app development process

accessible at any stage, point in time, and in every aspect

Discovery Phase

Jointly with you, our Business Analysts define and test the underlying idea of your mobile app, make a market and competitor research, and come up with a feature list for the app. The phase results in a clearly defined list of business and technical requirements for the mobile application to be built.

The duration of the Discovery phase is approximately 2-3 weeks.


The Wireframing phase focuses on sketching up your future mobile app. During this phase, we also create the mockups of your mobile application and test them (if so preferred by you, this happens in collaboration with you).

The duration of the Wireframing phase is 1-3 weeks.

UI/UX Design

During the UI/UX Design stage we create the screens of your mobile application. You are invited to discuss the look and feel we have created and to approve each of the created screens. During the UI/UX Design phase it also becomes possible for us to give you a detailed cost and time estimate for the project and precisely list the resources required to implement it.

The duration of the UI/UX Design phase is 1-2 weeks.

Application Development

During the Application Development phase, our mobile developers create the functionality of your mobile application.

Depending on the complexity and scale of your mobile app, the Application Development phase takes 4-5 weeks.


The Testing phase starts simultaneously and runs in parallel with the Application Development phase.

Usually, we conduct multiple types of testing that include Usability, Performance, Functional, Security, UX, and Regression testing.

Support & Maintenance

As your mobile application goes live, you can count on our long-term, effective, and cooperative support.

The duration of this phase can virtually be unlimited.
