What is mobile app architecture?

The mobile app architecture is a skeleton of the mobile application that defines all the components from a set of techniques to patterns needed to engineer an application while maintaining the industry standards. It acts as a framework that provides a roadmap and the best practices required to end up developing a well-structured application with no missing parts.

The components are selected in the architecture based on the app requirements, features set, tech stack, complexity, and design. A good mobile application architecture enables rapid app development and ensures hassle-free maintenance in the years to come.

Additionally, mobile app architecture terms cannot be interchangeably used with technology stack as it’s more concerned about the development process and business/user requirements. It answers everything from data collection and flows to platform and tech stack leveraged.

Importance of mobile app architecture

Mobile app architecture is crucial because it lays the foundation for an application that is scalable, efficient, and maintainable. If you have a well-designed architecture, you are assured to have optimal app performance and smooth user experience plus easy adaptability to changes likely to occur in the future.

Mobile app architecture defines how myriad UI components interact and ensure seamless integration and user-centric functionality. Moreover, it facilitates code reusability by simplifying the process of debugging and troubleshooting to improve overall app development cycle. Developers prioritize mobile app architecture to build robust apps that are capable to meet increasing user demands and industry standards.

Here are three essential factors showing why app architecture is important:


Mobile architecture for scalability allows an app to handle growing user numbers and data volumes without compromising app’s performance. This factor is essential for apps that experience rapid growth or timely fluctuations in usage. Developers design a scalable architecture to ensure that the app remains responsive and stable in any circumstances.


Today, data and transaction security are paramount in any mobile app development. Implementing robust security measures within the app architecture ensures protection against several threats like data breaches, cyberattacks, unauthorized access, and malware ingestions. Some of the essential components include encryption, authentication mechanisms, and secure communication protocols that all help build a secure app architecture to safeguard user privacy and confidentiality.


A well-designed app architecture gets us easy maintenance and updates of a customized application. Hence, it reduces the time and effort required for ongoing mobile app development tasks. Within the app architecture, modularization and clear code structure can contribute to easy maintainability as it enables developers to solve issues efficiently.

Which are the layers of mobile app architecture?

The mobile app architecture is divided into multiple layers that are essential as it makes the operational layers work individually without interrupting others. Also, the building and execution of each component improves the mobile application development architecture understanding and enable developers to fix the issues instantly. The mobile app architecture diagram makes it easy to understand.

Presentation layer

This layer is more about UI components and user process components that describe how the mobile app look and feel when presented to the end-users. During the presentation layer designing, the right type of data format, data validation, support for device form factors, and colors, fonts, & text location are taken care of. The UX design manages the user interaction with the app by understanding the complete journey throughout the app.

Business layer

This layer is more about how data is presented before the end-users as it encapsulates the data types that the application uses, loading data from databases/networks, and data processing. Also, business logic defines the data processing that needs to perform to turn the data into a meaningful form for the end-users. The business layer involves workflows, components, and sub-layers namely- the domain layer and the service layer. The business logic layer deployed on the user and backend server remotely minimizes the overall load.

Data layer

The layer meets the secured transaction needs of the businesses with a mix of service agents, utilities, and data access components. With growing data, it’s essential to select the right data format with a validation technique, which meets the scalability needs and invalid data input prevention. It meets the modification needs as the business requirements get updated. The data layer comprises two layers- the persistent layer and the network layer.

A persistent layer ensures easy data access from the mobile app backend in the same data format it’s stored. A networking layer offers the path for communication by establishing a logical connection, data forwarding, routing, and making network calls.

Service layer

The rarely known component of mobile app architecture lies between the presentation and data access layer. This layer involves service interface specification and enforcement, and translator components for data format translation. It aims to decouple the presentation from the nitty-gritty of business logic specifics so that multiple presentation layers are created which are updated without impacting the presentation layer.

Communication layer

The components in the mobile app architecture must communicate with each other in some way, which requires building a communication infrastructure for every component. For instance, when data is stored on the application permanently if changed or updated after some time, then direct communication between the data enables the storage of the right value instantly.

What are the top mobile architecture patterns?

The selection of the right mobile application architecture is all-important to drive business success with mobile app development. Implementing core logic, for example, in dynamic, scalable mobile applications is not possible. Architecture patterns with modular design can solve this problem. Here’s the list of different types of architectures that serves various business project needs.


The MVP model comprises three layers- model, view, and presenter. The model is a data-storage layer that’s created following business rules and enables communication of the components with the network layer and database. The view is a UI layer that improves data visualization and maintains a record of users’ actions to notify the Presenter effortlessly. The Presenter receives data from the model and makes decisions on what to show through UI logic. It helps with knowing the view’s status track and identifying the response to users’ input notifications.

The architecture pattern is preferred by the Android developers because it provides a codebase that’s easy-to-manage, and facilitates modularity and testability at scale.


The MVC model is divided into three parts namely- model, view, and controller that make the app maintenance easier. Model is a data layer that consists of objects, network code, parsers, and persistent. The view part is a UI layer that displays data and keeps tabs on the user actions to inform the presenter off the bat. The Controller works in-between model and view by sending messages back and forth following a set of defined rules.

The MVC architecture is favored for building dynamic websites where frequent updates are essential to reflect on the front end. For instance, the layout of all the Amazon product pages is the same, but they appear different due to distinct data updates from the database.


It refers to as model view ViewModel architecture that helps in the separation of design and code structure concerns. The model eliminates the need for putting the business logic in a controller or view, unlike the MVC model. It’s preferred for large-scale app development as it facilitates extensibility, code modularization, testability, and pluggability massively.

The Model layer is about abstracting the data sources, retrieving and saving data, and making the model and ViewModel collaborate. The View layer informs the users’ action to ViewModel. The ViewModel separates GUI development through GUI code.

Now since you are acquainted with different mobile architecture patterns such as MVC and MVVM etc., let us see some of the real-life mobile app architecture for major players in the market.

Real life mobile application architecture design examples

Real-life mobile app architecture examples show how different platforms and development approaches affect the overall app structure and performance. Each architecture type offers unique considerations like platform-specific features, code reusability, and development efficiency. Let us understand these examples to make informed decisions and optimize the app’s architecture for business goals.

Android Mobile App Architecture

MVVM separates different parts of the app, making it easier to manage and test using Android’s built-in tools. Here are some of the real-life Android mobile app architecture examples:

Model-View-ViewModel (MVVM): MVVM architecture separates the UI from business logic and data layers to promote modularity and testability. Android Architecture Components (AAC) such asLiveData and ViewModelcan facilitate such a pattern to enhance lifecycle management and data binding.

Model-View-Controller (MVC): MVC is known to divide the app into model, view, and controller components. Thus, for Android app, it promotes code organization and reusability while, at times, leading to tight coupling between layers and complexity in bigger apps.

Clean Architecture for Android: The clean architecture uses layers and inversion of code principles. The layers that compose this architecture are data, business, and presentation layers; in this architecture, each layer is independent and uses the interface to exchange data. This architecture offers myriad benefits like ease of testing and debugging, individual UI, and independent external libraries, database, and frameworks.

iOS Application Architecture

iOS apps generally divide component sections for easier management and functioning. There are newer approaches to make the entire development more streamlined.

Here are some of the real-life iOS mobile app architecture examples:
