Definition of App Architecture

Speaking in technical language, the architecture of the application is the structural elements and separate sets of interfaces connected in a single combination. Using this combination, a system is composed in addition to the framework behavior of all the structural elements.

But layman may have a slightly different point of view on this issue, much more understandable. Mobile application architecture is the methods, models, and designs that are used to create structured mobile applications. Instead of the word architecture, the word wireframe can also be used. It is on it that the work and quality of any software product are based.

Thus, everything that your application stands for: data navigation, user interface and user experience, platform, technical stack, and much more are mobile application architecture templates.

Why do you need a flawless apps architecture?

When planning and designing a software development project, you need to identify the basic steps that will be implemented by default. One of these steps will be determining the right architecture. Unfortunately, many developers simply ignore this step. What is the reason for this? With a slowdown in the development process, which leads to its expansion. The funny thing is that it is this fact that often causes various crashes in mobile applications.

Here are a few reasons why you definitely need corporate architecture:

  • it helps make software less error-prone;
  • it facilitates development and maintenance;
  • it is able to improve code readability;
  • it makes Agile much less cumbersome.

As a result, source code verification takes much less time.

Some problems associated with the lack of architecture or ignoring its importance are really striking. Understanding this, you will understand the need to develop the right architecture that will take into account all aspects of mobile application development.

“Architecture is intentions, not frameworks,” Robert Cecil Martin said. And we completely agree. Of course, there are different ways to implement a thing, and we are sure that you, like us, face difficulties every day in this area, but using these techniques, you can be sure that your application is:

Basics Elements of Application Architecture 

 A. Device determination

This is your first step, the main task of which is to take into account the type of device. To do this, you will need to analyze how accessible the development tool environment is, understand the screen size, processor resolution, and its characteristics. It is also important to study memory and its size.

Software or hardware directly affects application features. Therefore, it is very important that you have maximum information about all devices. Do not limit yourself to just one; otherwise, you risk developing an application that is suitable only for a narrow circle of users. Always ask yourself: what additional options are still available?

 B. Bandwidth Status

Of course, you already know that your application has a certain life cycle. During it, the application will face various events. One option is the lack of an Internet connection or a worsening connection. Consider the worst of all possible conditions in order to develop the architecture of your application. This will require the design of state management based on the worst-case scenarios, caching, data access mechanism.

 C. Perfect user interface

There can be no doubt that UI/UX  is one of the most important components of any application. This is what directly determines whether users will want to use your application. Therefore, you must take care of the development of the user interface, engage the audience in the process, and ensure its smooth operation without any errors. This is an important part of the infrastructure, which should become one of your top priorities.

 D. Navigation approach

In the navigation approach, the front is usually used to design the application architecture. But even in this case, you will need knowledge not only in the field of the backend but also in the external interface. You need to understand who your target audience is, what kind of requirements these people have for applications. Based on this, you will understand which personalized navigation elements will become a real salvation for your application, and which of them can simply be neglected:

  • Single view
  • Tab controller
  • Stacked navigation bar
  • Scroll views
  • Search based
  • Gesture driven
  • Model controller

But it’s not enough just to know all these elements in order to understand the architecture of mobile applications 100%.

It is important to understand that all such architectures are divided into three levels. Knowing and understanding these levels, your mobile application development company will understand how to create an architecture that will be in a class of its own.

First layer. Presentation

This is the stage at which you must think through your presentation. How do you show your application to users? To simplify this task for yourself, you must correctly understand the type of client, depending on the infrastructure used. In addition, it is important to consider what deployment restrictions a client may have. There is another important necessary task: you must choose the data format correctly. Do not forget about data verification. Its mechanisms should be reliable enough to make sure that your applications are reliably protected from invalid input. After going through these steps, you will understand how the end-user wants to see your application and how you should present it to the audience.

Second layer. Business

At this stage, your task is to consider the elements on the front of the business. If you talk with a layman, you can understand that he is considering options for how to present the business to end-users. In fact, there are several business components, a workflow, and two entity sublevels: Service and Domain.

Why do you need a Service level ? This is how you can determine the general functions of the application that will be available to your users. But the Domain layer focuses more on specific problem areas, studies the knowledge and experience associated with them.

Layer 3. Data

When developing access to data, you must make sure that this level meets the requirements of the applications. This is what you need to ensure secure and efficient data transactions. When developing mobile applications, it is also important to consider data service aspects. The development team must ensure the ability to easily change the level of data. Business requirements are constantly changing, and it is important that this level remains flexible.

This layer consists of some data components. These include:

  • access components
  • assistants
  • utilities
  • server agents

For three elements, two subheadings are used: Network-level and persistence level. The network layer is used for network calls, and the task of the second is to provide simplified access to data.

We want you to not only understand what the architecture of mobile applications is after reading this article. It’s very important to understand what a really good mobile application architecture is. What do you think helps make conventional architecture good? This is the principle on which it is based.

Some basic principles of mobile application architecture

Question: What is the foundation of mobile apps architecture ?

Answer: A good application architecture, regardless of whether the architecture is for Android or for iOS) should provide excellent assumption and programming patterns.

If your task is to speed up the development process, you must follow all these different conditions. It will also allow you to make maintenance a lot easier. Moreover, if you use platform-oriented technology and a well-developed architecture, this will allow you to solve the most complex business tasks that you will encounter during the development of applications.

Thinking of the perfect mobile app architecture, you can imagine the blueprint of the system. This is what will help you create the right chain of communications between all stakeholders, convey their ideas to end-users, and achieve business goals.

Creating a good architecture is a real event. This means that there are a large number of other principles that you must follow for an effective result. Thinking about which architecture to choose for application development, you can also focus on these principles.


What is portability? This is what determines how responsive the system is to changes. If we talk about mobile applications, where the environment is constantly changing. We are talking about both market and technological changes. If your mobile application architecture is good, it guarantees sufficient portability to respond to changes in a timely manner. In this case, the impact of these changes on the quality of the products will be minimal.


When the environment changes, you have to change the requirements. This is what helps get rid of errors, make the performance even better, etc. In this scenario of events, you must constantly maintain the application. So, it should be as maintainable as possible. It is important that you do not put too much effort into maintaining the system’s performance, because in this case, it will be simply inappropriate.


If you want your mobile application architecture to be good, you need to take care of such a thing as reuse. This applies to components and protocols. Updates or redesigns should not affect their performance. Therefore, when planning your architecture, take care of additional space.


Which app needs do you consider the most important? Of course, this is data security. The architecture of your application must be so robust as to guarantee all application’s adequate protection. Also, take care of synchronization with the organization’s security ecosystem and encryption of all data stored on the device.


When installing any applications, users want them to be free and also fast. Just imagine you downloaded the application, but it always takes too much time to get any information. With a high probability, you will simply refuse to use such an application. Think about how you can meet user expectations. Better yet, beat them!

It is this stage that will give you the most food for thought. By analyzing the desires of users, you can deeply immerse yourself in different types of application architecture. Discuss this with your team to find the best solution.

Apps architecture should not be thought out to the smallest detail; it should be thought out well enough to understand how much architectural errors in one part of the application break completely different, logically unrelated modules.

Good apps architecture should be profitable in any possible cases. It is your first priority. It is impossible to develop an easy and efficient product without decent architecture. Make sure it is easy to expand and modify, as well as test, debug, and understand. That will help you to make the grade with your app architecture.

Check-list to understand that your mobile app architecture is good

  • Efficiency: the application performs tasks and functions in any condition. The system is productive, reliable, and copes with all loads.
  • Flexibility: the chosen solution is easy to change, and there are fewer errors. Each element can be changed, and this will not be fatal for other components.
  • Extensibility: you can add as many functions as needed to the application.
  • Scalability: development and additional time are reduced. A good architecture allows you to direct development into multiple parallel threads.
  • Testability: the application is easily tested, which means that the number of errors decreases, and its reliability increases.
  • Reuse: elements and structure can be used in other projects.
  • Understandability: The code should be understood by as many people as possible. Many people are working on the application. A good architecture allows a layman to understand the project quickly.
