At this stage, the concept of the future application is defined, including its goals, key objectives, and primary features. A thorough market and competitor analysis is conducted to assess the strengths and weaknesses of existing solutions. The target audience is also analyzed to understand who will use the app, their needs, and expectations. Based on the collected data, a detailed technical specification (TOR) is created, outlining the structure, functionality, and core requirements of the product. Following this, the appropriate platform (iOS, Android, or cross-platform) and the technology stack necessary for development are selected.

Once the technical specification (TOR) is finalized, the user experience (UX) design phase begins. During this stage, user scenarios are developed, key screens, and functional interface elements are defined. Interactive prototypes are created, allowing for a visual assessment of navigation and ease of interaction with the app. After the prototype is approved, the design work commences. It is crucial that the interface aligns with the platform guidelines (Material Design for Android and Human Interface Guidelines for iOS) to ensure its usability and intuitiveness. The designer selects the color scheme, typography, and designs icons and animations. The final layout is approved by the client before moving on to the development phase.

This stage involves programming both the client and server components of the application. First, the backend is developed, which is responsible for data storage, processing requests, and interacting with external services. Following this, frontend development begins, focusing on the user interface of the app. Programmers create screens, connect the logic behind how elements function, and implement animations and integrations. If the app requires features such as authorization, payment systems, or card integration, the relevant APIs are configured at this stage as well. Development proceeds in stages, with regular testing and verification to ensure compliance with the technical specification (TOR).

Once the main development is completed, the testing phase begins. Specialists thoroughly check the app’s functionality, identify errors, and assess performance issues. Testing is conducted both on emulators and real devices, covering various operating systems and screen sizes. The usability of navigation, proper functionality of all features, loading speed, and overall stability are evaluated. After addressing any identified bugs, re-testing is performed to ensure the app’s reliability before the official release.

When the app is ready, the process of publishing it on the App Store and Google Play begins. Necessary materials, such as a description, screenshots, and an icon, are prepared. The app’s page is optimized (ASO) to enhance its visibility in the store. After submitting the publication request, the app undergoes moderation, which can take anywhere from a few days to a week. Once approved, the app becomes available for download. Simultaneously, marketing activities are launched, including advertising, promotion through social media, and managing user reviews.
