What does the mobile app development process look like?

From getting a request to creating a mobile app to launching it on the market, we go through a number of Agile iterations together with our clients. Each step in the process described below is an ongoing activity.

Product design

Business analysis

During business analysis, our BA specialists determine high-level features and functional, and non-functional requirements of the software project.

UX design

We build prototypes, making sure that the app’s look and feel is native to the platform and delivers a positive user experience.

Product development

UI design

User interfaces we design are convenient, simple, and comprehensible. We focus on striking a balance between app design and functionality.


Our backend developers build an app on the server side using Ruby on Rails. This backend app lets your frontend app’s API interacts with the database.

Mobile app development

The app development process is divided into iterations. We plan each iteration together with our clients and deliver results (implemented features) in the form of demos.


Testing is an inevitable part of any project at RubyGarage. We perform end-to-end testing to guarantee your project’s stability and to save money by detecting issues before the product goes public.
