02
Goal: To elaborate an intuitive design.
Analyzing the initial data and discussing the main and additional requirements.
Actions
Stakeholder interview
Deliverables
A document with clearly identified project’s requirements
The main goal of this step is to deliver an interactive and intuitive user experience with a polished look. By using various methodologies, we make sure the product design meets all the requirements set.
After determining the data a mobile app will collect and display to the end-users and workflows, we build the information app architecture.

03
Goal: At this stage, we focus on product development. We use the Agile methodology, which means that we divide the process into short sprints, each of which is dedicated to a certain piece of a software product. At the end of each sprint, we provide sprint results for customer review.
Our backend engineers work on creating database and server objects that store, protect, and process data.
Tools
Node.js, Angular.js
Deliverables
Fast server-side development

04
Goal: To check the application’s usability, security, compatibility, and performance.
This testing type is used to measure the performance of an app. Besides, it verifies load consumption, size, scalability, loading time, the time needed for responding to user requests. Performance testing involves load testing (checks app operation under a particular load) and stress testing (evaluates system behavior under extreme load).

05
Goal: Submitting an app to the app stores and timely improvement of the app to keep the audience engaged.
For launching an app, we prepare needed metadata (category, keywords, description, launch icon, etc.), make sure an app follows all development guidelines for a particular platform, and submit it for review in the App Store. Usually, a review process takes up to several days. For Android-based apps, there is no review process, and your application becomes available within several hours after submission.

If any of the questions haven’t been covered yet, in this section, you may probably find the answers.
How long does the mobile development process last?
It is impossible to indicate the exact time of the development of a mobile application because it depends on many factors, including the features and functionality of the application, the type of platform, the complexity of the design, the testing process, etc. You can contact us, and we will inform you of the approximate development time, taking into account the individual characteristics of your product.
How much does it cost to make an application?
As well as the development time, the cost of an application is highly individual and depends on the complexity of the application, its type, and the category. Our experts will calculate the development cost for you upon request.
What languages and technologies do you use for mobile application development?
We develop native apps for Android and iOS platforms as well as cross-platform apps. We use Swift and Objective-C for building apps for iOS, Java and Kotlin for Android app development, and React Native and Flutter for cross-platform development.
