How to Choose the Right Technology for Your Mobile App Project

Are you thinking of creating a mobile application? We have a lot to tell you about choosing the best tech stack for mobile apps. Don’t treat this process as just another step in the development plan. It will greatly impact the mobile app’s performance and efficiency, directly affecting your business. So, the main insight of this article is how the right tech stack impacts the further operation of your mobile app, how to choose the technology that will suit your project, and what the difference is between existing technologies. 

Main trends of mobile app technologies in 2024

The evolution of mobile apps in 2024 is unstoppable. They accompany us everywhere and make our lives much easier. To a large extent, their effectiveness depends on the technologies they were created with. They are responsible for ensuring the application performs its main functions and responds to user commands quickly and correctly. Here is a list of technologies that are truly reasonable today. 

• Cross-platform development. Tools like Flutter and React Native are gaining popularity among developers. They let them create applications for several platforms (iOS and Android) at once with less time and resources.
• Native development. It is used to create complex applications that require a high level of integration with the device hardware. For example, games, media content processing applications, banking and financial solutions. This technology maximizes the performance, stability, and access to all the features of the operating system (iOS or Android).
• Progressive web applications (PWA). They are becoming increasingly popular due to their ability to combine the benefits of websites and mobile apps. PWAs don’t require installation through app stores and can work offline, retaining some functionality even when there is no internet connection. They’re great for businesses looking to cut development costs since one app can run on lots of devices and platforms. 
• Low-code/No-code platforms. These platforms let people without deep programming knowledge create their own mobile apps using intuitive interfaces and ready-made modules. This significantly reduces the development time, but you should understand that it will be a product with a limited set of functions because you’ll only have what the platform provides, not what you want to see in the end.

New trends dictate to businesses what is relevant for users now and what technology can cover each need individually or comprehensively. The choice of technologies for mobile app development should also be approached responsibly, as it is a crucial stage of product development that should not be underestimated.

What to think about before choosing a tech stack for your app?

So, we identified why it’s so important to choose the right tech stack and how it affects the finished product. One of the points we made was that you should first consider lots of factors and analyze your business needs. In this section, we’ll take a closer look at this issue so that you, as a business, can consider key points before choosing the right technology. This is a short guide that will help you evaluate your project step by step. Here we go.

Determine the type of application and its functionality

This is the first step in deciding what to do next. Based on the established functions and the project scale, you’ll choose the technologies that work best for your business.

Choose your target audience and platforms

What platforms should your app work on? There are three options: iOS, Android, or both. Now think about what features of each of these platforms are important to your audience. Could the chosen technology handle what your app needs to do? Making the right choice will ensure the best user experience for your target audience.

Consider scalability and future upgrades

Think about how your app will evolve in the future. The stack should allow you to easily add new features and withstand the load as the number of users grows. Rest assured, if you don’t think about it now, you’ll probably need to in the future. And if you choose the wrong technology in the first steps, you’ll waste time and opportunities to grow your business. So, please, consider scalability. 

Estimate your time and budget

Some technologies allow you to develop apps faster, while others require more time. Accordingly, the need for support resources may also increase. There’s no one-size-fits-all all. Therefore, consider your timeframe and budget to achieve the best possible quality-to-cost ratio. And, of course, keep the goal of your application in mind. Because if you need a high-performance product with a large set of features in a month, it can be a challenge. Because such an approach requires more human resources, time, and skills. Take this into account as well. 

Choose a development team

You should consider your team’s technical skills and experience with similar projects or the availability of specialists in your stack. If the developers are proficient in certain tools, it can speed up the process and reduce risks. Choosing a team takes time, but it’s worth it.

Think about app security and support after the launch

Make sure that the technologies you choose have a high level of security and can be updated regularly. This is especially important for protecting user data and ensuring the stable operation of the application.

What is Native technology for mobile apps?

In this section, we’ll look at the technical side of native app development that should be applied in 2025. But first, a short description of native apps. These are mobile apps built for a specific operating system – iOS or Android. Written in Swift for the iOS platform or Kotlin for the Android platform, they adapt to the device and work really fast. Apple and Google developed these programming languages specifically for creating apps on their respective devices.

Such applications are suitable for you if you plan to create an app with the integration of device functions (camera, geolocation, etc.), games with high efficiency and fast response, and applications with a large amount of data, a big audience, and high performance. It’s a good choice for large projects where interface detail and speed are key. So, the technology stack includes the following key elements:

• Programming languages

Today, iOS apps use Swift, which is a modern language from Apple that provides high performance and access to all iOS features. This is your reliable assistant if you plan to create a large-scale project on the iOS platform. 

To work with Android apps, developers choose Kotlin. This is the official language for Android, which simplifies the development process and provides more features to create a reliable application.

• Integrated development environments (IDEs)

Xcode is used for iOS. This is the official development environment from Apple, which allows you to fully work with the code, test applications, and use all the available features of the platform.

For Android, we recommend Android Studio. This environment supports Kotlin and Java and offers powerful tools for creating, testing, and optimizing applications.

• Frameworks and libraries

For iOS, we recommend SwiftUI. This is a new framework for creating user interfaces that greatly facilitates the development process and improves performance.

For Android, the best choice is Jetpack Compose. This is a set of libraries from Google that helps speed up development, simplifies application lifecycle management, and ensures compatibility with different versions of Android.

• Testing and CI/CD

Popular tools for automated testing today are Firebase Test Lab with Jenkins CI (for Android), and XCTest (for iOS). This is a common set that lets you conduct comprehensive testing of mobile applications. To automate the deployment process of applications in stores (App Store and Google Play) developers use Xcode Cloud – a delivery service built into Xcode and designed for Apple developers. 

• Cloud services and backend

Android and iOS use a single cloud platform from Google – Firebase. It provides databases, authentication, analytics, and other services for mobile applications. For more complex backend solutions and scaling, it’s better to use AWS, Google Cloud, or Azure. 

• AI tools

Google offers ML Kit, which allows adding machine learning capabilities such as image or text processing and object recognition. The company also uses Dialogflow for conversational interfaces and chatbots. Apple, on the other hand, offers Core ML, which allows adding features such as text or speech recognition, which significantly increases the efficiency of mobile apps.

What is Cross-platform technology for mobile apps?

A cross-platform app is a mobile app that runs on both iOS and Android simultaneously. React Native or Flutter technologies are used to develop such applications. They are convenient because they allow you to write code that can be adapted to different platforms. This is a good option if you’re planning a quick start and want to launch on both iOS and Android. 

It’s also a good choice for startups because it doesn’t require additional funds to create separate app versions, and everything works in one system. If there is no need to use the device’s capabilities to run the application. Or if you want to create an application where performance is not a priority, but only functionality. In short, this is your option if you need to reach not a big audience with lower development and support costs. 

Cross-platform mobile app development will remain popular in 2025 because of the time and resource savings. Such apps are the right choice if your business goals align with their functionality. So, let’s consider what technologies you will need to develop cross-platform mobile apps.

Frameworks for cross-platform development

Two of the most popular frameworks are Flutter and React Native. Flutter is known for its flexibility, rich widget library, and ability to create efficient and attractive app interfaces. React Native lets teams write one code for both platforms with access to native components. With this approach, you get high performance and native compatibility.

Programming languages

For Flutter, developers use the Dart language. It’s easy to learn and ensures high application performance. For React Native, it’s JavaScript/TypeScript. With their help, developers work with front-end development and easily adapt to any changes in the application system. For UI development, Flutter uses Material Design technology since React Native has its own component library. 

Integrated development environments (IDEs)

Visual Studio Code or WebStorm are suitable for both React Native and Flutter. These environments support JavaScript, TypeScript, Dart, and other languages needed to develop cross-platform apps.

Backend and cloud services

Firebase is used for authentication, real-time database, and analytics. For scalable backend, data storage, and other services, developers use AWS Amplify or Google Cloud. 

Testing and CI/CD

For testing React Native apps, teams use Detox, and for Flutter – Flutter Drive. To test applications on both platforms, Appium is the best choice. GitHub Actions, Bitrise, and Jenkins are recommended for automating the building, testing, and deployment of cross-platform applications. 

What is PWA technology for mobile apps?

Progressive Web Apps (PWAs) are web applications that work like websites but perform the functions of native mobile applications. They work offline and don’t have to be downloaded, so you can use them in a browser. Such apps are suitable for businesses that want to create a user-friendly application but don’t have the extra budget to create separate versions for iOS and Android. 

For online stores, media, and content platforms, PWA lets users read online articles, receive notifications, and view content even with poor Internet connections. Also, if you are a startup and want to test your idea on the market with a universal application for all devices, choose PWA development. However, please be aware of some of the drawbacks you may encounter when scaling the system in the future. 

The technology stack for creating PWAs provides high performance and flexibility in the development process. It includes the following modern tools and frameworks.

• HTML5, CSS3, JavaScript: These are the basic technologies for creating the web application structure, styles, and interactivity. They provide a pleasant user experience and create the framework for the future application.
• React, Angular, Vue.js: Frameworks that are highly popular among developers. They’re great for building user interfaces and providing easy updates.
• Service Workers: A key component of PWA for offline work, caching, and notification management. It does everything to ensure that content can be accessed without the Internet and that notifications appear on time.  
• Web App Manifest: A JSON file (JavaScript Object Notation) for storing and transferring data between systems in the form of structured text. It allows applications to work like native ones and defines icons, start screens, colors, and installation behavior.
• HTTPS: A mandatory element for PWA applications that creates security over secure connections.
• Push API: Used to implement push notifications that work even when the web application is not open. These are the small windows you see on your desktop when you have already closed the browser. 

What’s the difference between PWA, Cross-platform, and Native technologies?

The main thing that distinguishes PWA, cross-platform, and native apps is the approach to mobile app development, their functionality, and areas of use. We’ll compare these apps so you can pick the one that fits your business needs best. Let’s start with PWA. 

From the previous section, you already know that Progressive Web Apps are web applications that we use in a browser, but they look like mobile apps. They work on any device and in any browser, even offline. They also don’t require installation from app stores, which saves money on maintenance and development. But there are certain nuances of such apps. It has lower performance, limited functionality, and access to the device’s functions compared to native apps. Considering both the pros and cons of such applications, we can say that they will still be a good choice for projects with a limited budget, startups, and those who intend to enter the market quickly, without the need to develop large-scale projects.

A cross-platform app runs on multiple operating systems (Android and iOS). They share a mutual code, but they are displayed and function as native apps on iOS and Android. Their main advantage is fast development and midsize launch budgets. It’s because you don’t have to wait for two apps on different platforms but get one ready-made product. However, they have slightly lower performance and often have system conflicts, i.e. restrictions on access to specific functions of each operating system. They are the right choice for businesses that need a single application that runs on different platforms all at once.  

Native apps are developed separately for each platform – either iOS or Android, without combining them. They have maximum performance because they have full access to the capabilities of the operating system and application functions and can easily adapt to any updates. Of course, such development requires more time and money, as separate versions are created for each platform. But as a result, you get a highly efficient product with a wide range of functions and features. If you are planning to create a project where high performance, complex visual elements, bespoke design, and full access to hardware features are key factors, this is definitely your choice.  

So, before choosing one of the above options, analyze in detail the goals of your business and future product, your budget, deadlines, and other factors. And if you make the right choice, you’ll get the well-suited product that will help your business and brand grow.
