As the pandemic has evolved, we've seen a shift in how people use apps. People are using apps to stay connected with family, friends, and loved ones. We're also seeing an increase in the number of apps being used for business purposes.

People are using apps to stay connected with family, friends, and loved ones. We're also seeing an increase in the number of apps being used for business purposes. Apps are also being used for personal finance management, health and wellness, and education.
The most popular categories for apps are games (31%), business, productivity, health, and fitness.
According to Statista, 2.1 billion apps are available on the Google Play store, while 3.8 billion are available on the Apple App store.
The demand for new apps is not going away, with sales of 5G devices driving demand for new apps, with post-pandemic device behavior sticking around, including the drive for shopping convenience and delivery services as well as free time fillers, whether games or home fitness apps.
Apps can be an excellent way to keep customers connected to your business. They can help you to engage with customers in new ways, such as sending push notifications or live streaming events. They can also make it easier for customers to get information about your products and services. Apps are also a great way to make it easy for customers to contact you. It can help you to improve customer service and increase your customer retention.
What is Mobile App Architecture?
Mobile app architecture refers to a set of rules, techniques, processes, and patterns to develop a mobile application. There are four core principles in agile development, which help developers build and release quality software.
Mobile App Architecture vs Mobile Tech Stack:
A mobile app’s architecture and mobile tech stack are often used interchangeably, although incorrectly. The mobile technology stack is the set of technologies and technical frameworks used to build mobile or web apps. It includes the back end (database, servers, programming languages), and the front end (user interface). It does not cover what your business needs are, nor how to create the app.
The mobile app architecture consists of the parts of the app that are made up of all the questions about why what, how, and what data is collected, how the data moves, what the app looks like, for what platform, and using what tech stack.
How Many Layers Are There in Mobile App Architecture?
Representing mobile application architecture using three layers: Presentation, Business Logic, and Data.
1. Presentation Layer:
There is a presentation layer that contains the processes and components to deliver the app to the user. Developers who build the presentation layer need to be concerned with what users see and feel when using the app. When we speak of the presentation layer, we're really talking about the user interface (UI) and the user experience (UX).
User interface (UI) is concerned with the design questions, such as colors, fonts, placement, and overall design.
User Experience (UX) is an interactive process where customers understand and feel what the app is about, using a detailed understanding of what a user wants and feels.
Developing the presentation layer means deciding whether or not to use a specific type of device (e.g. smart phone, tablet, laptop) to deliver information, so it’s consistent with the design standards of each.
2. Business Layer:
The business layer is responsible for the logic and rules that dictate data flows between applications, as well as for application operations and business flow regulation.
This layer is responsible for:
● Security
● Data caching
● Logging
● Data validation
● Exception management
The business layer exists on the server or on the client device, depending on whether the operation takes place in the cloud or locally.
3. Data Layer:
The data layer includes all the services that are used to access your data and perform the necessary operations.
These layers can be thought of in two ways:
● Persistence – data access with data sources via API
● Network – network communication, routing, error reporting
The design of the data layer should include thoughts about how to validate and maintain the data.
Android Mobile Application Architecture:
Apps for Android are different from apps for iOS or Windows platforms. Apps developed for Android are one type of native application. They’re also known as “Android apps. Apps created for Android support Android languages (Kotlin and Java) for devices from different manufacturers including Google, Samsung, Sony, and Nokia.
There are many different architectures for Android applications. The most popular one is Clean Architecture. It is recommended by Google. In Clean, the architecture is based on layers, and it's easy to test.
Clean is the latest book from the Gang of Four and it focuses on the same 3-layer architecture they introduced in Designing Data-Oriented Applications. In clean architecture, the domain/business layer shouldn't depend on the other layers. Instead, the business layer should leverage the other layers. While this can be difficult to understand, it makes it easy to add to and scale apps over time.
iOS Mobile Application Architecture:
Native iOS apps are developed using Objective-C and Swift languages, with Apple providing clear best practices over app architecture with the MVC model (Model-View-Controller).
The MVC model is composed of the following components:
Model: The data layer (persistence, model objects, parsers, managers, networking code).
View: Similar to the presentation layer, a reusable layer that represents the app to the user.
Controller: A mediator level that communicates with an abstraction via a protocol.
The Model-View-Controller pattern supports rapid and parallel development, with the ability to create multiple views. It's a great option for mobile development.

The Conclusion:
The success of any mobile app depends upon careful consideration of architecture and tech stack.
It’s important to consider what your app’s requirements and user stories are before writing code. This will help plan what features to include, how to include them, and how these features will be connected through layers.
There are many factors in the decision which, when inaccurate assumptions are at play, can result in an app that doesn’t meet its goals.
