What is the front end of a mobile application?
Frontend is the client-side part that is deployed on the user side. The frontend combines two components of the interface:
- UI design – the visual part, the appearance of the screens as seen by the user;
- The UX part of the interface that defines the execution of user scenarios.
If backend is the component hidden from the user, which provides the logic of the application operation, the frontend is the visual part that the user directly contacts. Thanks to frontend development, the design visual turns into a live interactive interface: buttons, screen animation and navigation elements work, the user can navigate between sections and perform targeted actions. To ensure the coherence of such processes, client-side and server-side integration is performed.
Main components of the mobile application front-end
Responsive UI Layout
We create the visual part of the interface using the React Native framework and React JS — a JavaScript library for building interactive interfaces.
- We ensure the screen structure matches the agreed UI design layouts, organize visual components, and position blocks on the screen (buttons, menus, forms, text blocks).
- We adapt screens for all types of mobile devices with different resolutions in accordance with iOS and Android requirements.
- We integrate native components from Apple’s Human Interface Guidelines (HIG) and Google’s Material Design.
- In the case of developing a universal cross-platform product, we ensure the interface displays correctly on both operating systems.
- We configure fonts, backgrounds, colors, gradients, shadows, effects, margins, and spacing.
The result of the layout process is a dynamic, responsive interface that quickly reacts to user actions and commands.
Interactivity and UX
The frontend serves as the visual environment where the user interacts — performing actions, using features, and navigating the app’s structure. To enable these capabilities, we create interactive UX elements that will later allow the app’s logic to be implemented. To enhance development efficiency, we apply a component-based approach — breaking the frontend into reusable parts that appear on different screens and are used multiple times. We create interactive elements such as:
- Buttons and icons for performing actions and confirming user choices;
- Navigation panels for moving between sections of the application;
- Forms and text fields for data entry and submission;
- Menus for accessing app features and sections;
- Animated transitions to enhance the visual aspect during user interactions;
- Drag-and-drop effects for convenient component rearrangement on the screen;
The result of this stage is the creation of a fast and user-friendly interactive interface that is comfortable to use and responsive to user actions.
Backend Interaction
The functionality of a mobile application is ensured through the interaction between the frontend and backend — the client-side and server-side parts of the product. Commands received from the user via the frontend are transmitted to the server. The server side analyzes the request, accesses the databases, and returns a response to the application — the user sees the result of their actions on the screen (operation completion, navigation to another section, menu selection, form submission, etc.). This interaction is organized through an API (Application Programming Interface).
As a result, we get not just a dynamic interface with all the necessary interactive elements, but a fully functional mobile application that offers users advanced capabilities and allows them to perform targeted actions — interacting with menus, forms, buttons, built-in features, and integrated external services.
Benefits of professional front-end mobile application development
Stages of front-end mobile application development
We analyse the initial data, assess the complexity and functionality of the application, and select a technology stack for front-end development. We develop a detailed work plan - from adaptive screen layout to ensuring stable interaction between the front-end and back-end. We create a technical specification and after approval, we start work.
If the client requests turnkey mobile development and does not have its own design layouts, we create a design from scratch - the visual UI part and the UX components of the interface. We work out user scenarios and navigation schemes, create screen structure and visual design style. In order to harmonise the layout, we carry out prototyping - the prototype visually demonstrates the structure and principle of interaction of interface components.
Coordinated design layouts and prototypes are used for front-end development - adaptive screen layout, interface styling, interactivity. Static design is transformed into a dynamic interface with transitions, animations, effects, active forms, buttons and navigation elements. We perform adaptation of the client part for gadgets with different resolutions.
We test the front-end, checking for bugs and glitches to ensure the interface works smoothly. Based on the test results, we fix bugs, optimise the code and screen structure, and prepare the interface for further integration with the backend.
To ensure smooth operation of the mobile application, we integrate the front-end (client part) with the back-end (server part) via API - a set of rules and tools for organising the client-server architecture.
We provide technical support services after the launch of the mobile application - we release updates according to the product development plan, respond to user requests and fix bugs, maintain stable operation of the interface, monitor performance, generate reports on the technical status of the application.
APPLICATION DEVELOPMENT TECHNOLOGIES
Mobile application front-end development costs
The cost of the front-end is calculated individually for each project, depending on the complexity of the design, structure and functionality of the application.
Complexity of structure and design
The price of mobile application page layout is determined by the peculiarities of UI/UX design and structure, the presence of complex interactive components.
Application functionality
The cost of a mobile application front-end depends on the complexity of the functionality and the need to integrate with third-party services.
Native and cross-platform
Pricing for front-end development takes into account the operating system (iOS or Android) or the need to create a cross-platform product.
Additional services
Other stages of mobile development - from design to publishing, support and promotion of the finished product - are included in the cost of project realisation by agreement.
