Mobile App Architecture: Everything You Need to Know

8 Mins read

The worldwide epidemic and changing expectations on how and when consumers engage through mobile are helping to drive the growth of mobile applications. The particular blog will show that app downloads are up by 31% year-over-year, while sessions, a measure of user engagement, are up by 4.5%. The Apple App Store has more than 2.22 million applications, while the Google Play Store has more than 3.48 million apps.

Post-pandemic device behavior, such as the need for shopping ease and delivery services and free time-fillers like games or home fitness applications, will continue to fuel the demand for new apps. Although COVID influenced part of this behavior, most of these patterns were already on the increase before this. Customers in B2B and B2C worlds expect companies of all sizes to cater to their mobile needs, which has prompted many to look into developing mobile apps. Hence getting your apps designed from any of the leading android app development company india is very vital. You’ll learn about mobile app architecture in this tutorial, which will help you plan for the future of mobile apps.

What Is Mobile App Architecture?

One of the essential concepts in mobile app development is mobile app architecture. These guidelines assist programmers in creating an app that satisfies the needs of both the company and the industry.

Why Is A Good App Architecture Important?

Many applications are being created nowadays without any consideration of a standard design. A lack of architecture leads to an app that is

  • A more time-consuming and expensive process.
  • Hard to maintain, significantly if staff members change.
  • It’s more difficult to expand on or increase the size.
  • Testing is a challenge.
  • Mistakes are more likely to be committed.

KISS, DRY, and SOLID software development outsourcing concepts should be used at the relevant phases of the development of a mobile application to speed up development and provide a clear channel for the data flow that makes work simpler and promotes clarity over how to extend or expand the app in future iterations,

Flexibility and Agile development approaches benefit from a fully defined mobile app architecture, as do testing and future maintenance, which are simplified and less prone to errors. With a well-designed mobile app architecture, you’ll save money in the near term and time in the long run. Hence always get in touch with the best in-class front end developers.

There are no platform-specific aspects to a good architecture; it may be used on both the platform of choice and cross-platform. There are several ways in which we may think of mobile app architecture as a skeleton from which we can construct the app’s essential components.

What Is the Average Number of Levels in a Typical Mobile App?

App architecture is often shown in three layers: display, business logic, and data. This is the most frequently used visual depiction.

Layer 1: Presentation

This layer includes everything that goes into delivering the app to the user. In the presentation layer, designers think about how the app will look and feel to the user. The user interface (UI) and the user experience (UX) comprise the presentation layer (UX).

Colors, typefaces, layout, and general design are under the umbrella term “User Interface” (UI). As part of the User Experience (UX) team, you’ll be responsible for the way customers engage with the app and how they feel about it. Developers must consider the platform and device type while creating the presentation layer to ensure that the presentation adheres to the relevant standards.

Layer 2: Business

Rules and logic that govern data interchange, operations, and workflow regulation are found in the business layer. This layer is in charge of the following tasks:

  • Security.
  • Caching is a method of storing and retrieving data.
  • Logging.
  • Validation of data.
  • Management of anomalies.

The business layer might be on the server or the user’s device, depending on the app’s activities and the resources required for each one.

Layer 3: Data

It comprises all the data utilities, service agents, and access components necessary to facilitate data transactions. There are two sections to this layer:

  • Using an API to get data from a variety of sources.
  • Communication, routing, and fault reporting are all functions of the network.

Consideration must be given to how the data will be maintained and validated when designing this application layer.

Important Considerations for Mobile App Architecture Development

1. Type of Equipment

When creating a mobile app, it’s important to consider the various smartphone models in use, as well as the platform (iOS, iPadOS, Android, Windows, Cross-platform). Having this information will help you select the best proportions for your project. ‘

When building a mobile app, the following elements should be taken into account:

  • DPI (dots per inch) is a measure of screen resolution.
  • The resolution of the screen.
  • A computer’s processing unit (processor).
  • Storage in random acc (memory).
  • When it comes to this stage, the objective is to provide the greatest possible experience for every user, independent of their device choice (tablet vs. mobile, model variations), so they can enjoy the app.

2. Frameworks for Development

The design of the mobile app architecture and the tech stack are both influenced by the use of development frameworks. Front-end and back-end developers may use frameworks to quickly and easily create online applications.

It is possible to construct mobile applications using a variety of front-end frameworks like Bootstrap, Foundation, React, Angular and Vue. There are a wide variety of frameworks for building back-end (server-side) applications, depending on the programming language and target platform used.

3. Bandwidth Issues

It is critical to do user research in order to learn more about the intended audience. Depending on where you are in the globe, you may or may not have access to 5G, which is available in certain countries but not in others. For example, a highly dynamic and graphic-heavy app will not be suitable for rural applications.

In addition, the design of the user interface and user experience (UI/UX Design) is important.

First impressions (how it appears – a great UI) and user retention are both influenced by mobile app design (how it operates – a strong UX). Users’ expectations and best practises for each operating system (OS) and device type are constantly changing, making mobile UX more difficult. In the design process, the mobile app architecture must strike a balance between UI and UX. Begin by learning about the fundamentals of mobile UX design and 2021’s hottest mobile UX design trends.

4. Getting about

Navigating a website is a direct way for users to interact with the design. A well-designed mobile user experience (UX) makes it easy for users to navigate the website and discover new content. Getting around requires some familiarity. The following recommended practices for mobile app navigation make it easier for customers to utilize the app and reduce friction:

With its recognizable three-line layout and prominent placement on mobile applications, the hamburger menu has become a favorite among developers. Reduce the number of times users have to click through to reach their desired destination by adding a menu that appears when the mouse has hovered over.

  • Search — The normal place for the search bar is at the top right of the screen.
  • Navigating an app may be as simple as using a horizontal bar, a vertical bar, drawers (for concealed navigation), or even tabs, depending on the design of the program (screened content with fixed titles).
  • Navigation is made simpler by the use of recognized icons, such as the home, search, photographs, and folder icons.
  • Labels that describe the purpose of a button, choice, or feature are an important part of intuitive labeling.
  • Site categorization may make or break site navigation, depending on how the categories are titled and arranged on the website. Rely on industry standards for information architecture.
  • Navigation may be simplified with the use of gestures, such as swipes.
  • The app’s ability to scroll vs the immovable components.
  • Usability may be improved by using the thumb zone as a navigational aid.

The Architecture of Android Mobile Apps

One kind of native app is an app created for a particular mobile platform, such as Android. Google, Samsung, Sony, and Nokia provide mobile devices that can run Android applications written in the Kotlin or Java programming language. Even though Android does not have a single suggested design, Clean Architecture is the most widely recognized Android architecture for mobile applications. Hence you must always look for dedicated android app developer to develop your android apps in the best manner possible.

Using layers and inversion of control, Clean’s architecture is based on these ideas. There are three layers: the business layer (also referred to as the domain layer), which is what Clean is all about. The domain/business layer must not be dependent on the other levels in a Clean design but must use interfaces. Even though this might be challenging to comprehend, it is simple to grow and expand programs.

The Architecture of Ios Mobile Apps

Objective-C and Swift are the languages of choice for developing native iOS applications, with Apple offering explicit best practices over app design via the MVC approach (Model-View-Controller). While there are various possibilities for iOS, the MVC model consists of the following components:

  • The data layer of the model (persistence, model objects, parsers, managers, networking code).
  • View — A reusable layer representing the application to the user, similar to the presentation layer.
  • A protocol is used to interact with an abstraction at the level of the controller.
  • It can generate many views using the MVC architecture, making it a fantastic choice for mobile programming.

The Architecture of Hybrid Mobile Apps

It is possible to create hybrid mobile applications using native and web technologies. Rather than relying on platform-specific code for the front end, hybrid applications use platform-neutral technologies like JavaScript, HTML, and CSS in the backend. Apache Cordova and Ionic Capacitor are two popular plugins for hybrid applications, allowing them to use native platform functionality. Regarding speed and ease of updating, hybrid mobile apps rank towards the top of the heap, but they fall short when it comes to more complex, dynamic, or feature-rich applications.

The Architecture of Cross-platform Applications

Cross-platform programming, like hybrid architecture, uses a single codebase with platform-specific features in each native shell. Frameworks such as React Native, Flutter, and Xamarin build cross-platform applications rather than web languages. In many cases, cross-platform applications provide a user experience that is more like a native application, making them more appealing.

Is There the Right Mobile App Architecture for Your Business?

When deciding on the final design architecture for a mobile device, these are the aspects to consider:


Architecture selection is influenced by various factors, including the developer’s expertise, the market’s state, and the development method. Native and cross-platform developers typically lack the IT skills needed for rapid, agile development, which might result in an outdated app when it reaches the market.

Analysis of the target market:

Find out who your users are and what they want, then do a competitive analysis and create personas for each of them, as well as user stories, flows, maps, wireframes, and prototypes to test your ideas.

Requirements for critical features:

For cross-platform software, the business needs should drive the feature list.

Choosing a Platform:

In terms of UI and UX, best practices will differ depending on the platform.

How long will it take?

In certain designs, specific aspects or integrations take longer to create than others, which should be considered before making a final decision.

The First Step Is To Build A Test App:

There is no substitute for a real-world test app for iterative and continuous feedback in agile development. This is an elementary program, but it delivers a lot of helpful information on how well the design meets the target user’s needs.


For any mobile app to be a success, the architecture and technology stack must be carefully considered. This will help you decide what features to include in your app (and how to add them), link them (via layers), and how the app will be used. Several elements might lead to an app that doesn’t match expectations if wrong assumptions are made throughout the decision-making process.
