As an investor, you should also be prepared to have a say in selecting programming languages, frameworks, and tools for building your very own mobile application. 


The mobile app tech stack should be cost-effective, especially with a tightt budget. It’s also essential to understand the technical possibilities and constraints of various technology stacks when it comes to implementing your ideas.


Your choice should be determined by the problems the app is solving. Ask yourself and the developers working on the project:


  1. What shall we do to create the best user experience?
  2. How are we going to ensure security?
  3. Is performance a priority now, or can we deal with it later?


Ideally, the developers should choose a tech stack to accommodate future horizontal and vertical growth. Once a prospective technology has been identified, run through a checklist together:

Mobile app backend technology

So, if you want to choose the best stack for mobile app development, the first thing you need to do is decide on the backend. ‘Server side’ and ‘backend’ are umbrella terms for the layer where the business logic and data come together to deliver the mobile app’s core functionality. Backend responds to user requests, accesses the database, and executes the Create/Read/Update/Delete operations.


The list of most popular technology stacks out there includes, but is not limited to:


  • LAMP is the abbreviation for Linux (a server operating system), Apache (the webserver), MySQL (the database), and PHP or Python (the scripting languages). The stack thus consists entirely of open-source software components. It’s also compatible with other open-source and free software packages. LAMP is considered the best robust and reliable backend technology for mobile app sets; flexible, customizable, and easy to use.


  • Nest.js is the popular framework for building server-side Node.js web applications. It utilizes progressive JavaScript, is built with and fully supports TypeScript, and combines elements of OOP (Object Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming).


  • Vue.js. is a progressive framework for building user interfaces and single-page applications. It can easily scale between a library and a framework depending on different use cases. Vue consists of an approachable core library that focuses on the view layer only, and an ecosystem of supporting libraries that helps you tackle complexity in large single-page apps.


  • Python-Django can be used successfully to build backend services for a mobile application. The multifunctional framework is open-source, mature, stable, and has excellent documentation. It’s suitable for whipping up working prototypes and building rather complex apps quickly. Read Also: Django Crispy Forms


  • Ruby on Rails is another open-source and free framework. It promotes quick web development thanks to a rich repository of library integrations. This and other benefits of RoR also make it a favored technology for building mobile apps that are simultaneously expandable and multi-purpose. RoR is compatible with MySQL and has its own built-in database.


Native mobile technology stack

A native mobile application is designed to perform on a specific mobile OS. Besides the faster performance and higher security, such apps come with more excellent responsiveness, gesture control, device notifications, access to the device’s camera, GPS, contacts, and other hardware/software, and the ability to work offline. Native mobile app development is deemed to be more cost-effective as well.


Currently, the leading platforms are iOS and Android.

Technology stack for iOS app development

To build iOS apps, you can use such programming languages as Objective C and Swift. The open-source Swift is newer and evolving quickly. Its code is simple and intuitive for beginners or experienced developers working with other languages, hence the growing number of developers and companies favor it for building iOS and macOS applications.


The recommended integrated development environments (IDE) are:


  • Apple Xcode: The IDE provides integrated documentation, support for Git repositories, source code editor to transform and refactor code more efficiently, a graphical UI builder, and a robust built-in testing engine for creating applications for all Apple platforms. Xcode is free of charge.


  • IntelliJ AppCode: It’s fully compatible and interoperable with Xcode and supports Objective-C, Swift, C and C++, JavaScript, XML, HTML, CSS, and XPath. The IDE comes with strong refactoring capabilities, on-the-fly code analysis, debugging, and support of several testing frameworks. The subscription prices start at $89/year, but AppCode is more stable than Xcode, and the ability to generate and change code quickly saves much time.


For example, using Swift, we created a photo editor app that people can use on the go to polish their photos and share them via favorite social media.

Technology stack for modern Android mobile applications

If you want to create a native app for Android, you can choose Java or Kotlin. The latter’s abilities are similar to those of Swift. Google backs Kotlin, so it may be the future. The recommended toolkits are:


  • Android Developer Tools for Eclipse IDE: The ADT plugin provides a guided project setup, tools integration, custom XML editors, graphical UI builder, emulators, and test automation support. App development with ADT is arguably the quickest way to start. The plugin is free, but compatible versions of the Eclipse IDE and Android SDK must be installed first.


  • Android NDK: The Android Native Development Kit facilitates the implementation of application parts using C or C++, which compiles to native code. Developers working on certain mobile apps can reuse code libraries written in those languages. Although such code requires higher-level skills, it’s more stable and faster to execute. The tooling is also free of charge.


  • Android Studio: Android Studio’s code editor provides code completion for Kotlin, Java, and C/C++. There is also an efficient visual layout editor, template-based wizards for common application components, a rapid emulator for different configurations and features, built-in profiling tools, and abilities to reduce the app size and create from a single project build variations for different devices. These and other features facilitate speedy and more productive development on all devices. Android Studio is free to download.


Using the above technologies, we developed a video player mobile app for Android with audio normalization for the most comfortable viewing. The app provides a voice enhancing feature, smoothing sharp drops in sound, smart volume correction of the entire audio track, and normalization loudness of special effects.

Technology stack for cross-platform mobile apps

Сross-platform mobile app development means simultaneously creating mobile apps for multiple platforms. Developers build such applications using a combination of web and native technologies.


Building an application for several platforms can give your business a competitive advantage, help reach out to a broader target audience, and increase sales. Code repeatability also helps reduce costs.


Below we share some popular frameworks for creating cross-platform apps:


  • Unity: Great even beyond gaming, Unity allows developing applications for numerous platforms and hybrid apps. The IDE provides enhanced built-in support for audio, animation, and physics. Ready-made pieces of applications are available at the Asset Store. There’s a free version for beginners, but monthly subscriptions offering more advanced features start at $35 per seat.


  • React Native: Facebook’s open-source UI design library is one of the top mobile JavaScript frameworks. Its reusable ‘native components’ can be compiled directly to native counterparts of Android or iOS apps. Also, if you need to improve an existing application but don’t want to overhaul it, you can incorporate React Native components into the existing code. Third-party plugin compatibility allows accessing the device’s functions while using less memory and loading faster. React Native’s library includes Flexbox CSS styling, inline styling, debugging, and support for deploying to App Store and Google Play.


  • Flutter is Google's free and open-source UI framework for creating native mobile applications. Using Flutter, developers can create mobile applications for both iOS and Android with a single codebase and programming language. It makes developing iOS and Android apps simpler and faster. 


For example, using Flutter, the Onix team successfully built a delivery app with all the required features such as tracking the orders, categories and filters, searching for an item, choosing a restaurant, payment, and many more.

  • What is a mobile application technology stack?

A technology stack is the combination of programming languages and software products that are used to create a mobile or web application. A stack is created when one layer of an application is built atop the other. Most mobile application technology stacks come with two software components: client-side and server-side. These are also known as frontend and backend.


  • Why is it so important to find a suitable technology stack?

The chosen mobile app tech stack will largely determine whether your mobile application will be scalable, secure, maintainable, and perform well. It will also directly impact your budget and time-to-market. The wrong technology can set your business back by months, whereas a well-chosen tech stack gives a competitive advantage and helps it grow. However, it's important to note that not only technologies play an important role in the app development, but also the specialists with whom you cooperate and who surely know how to use the chosen technologies.


  • How to select the right tech stack for mobile app development?

The larger and more complex your project, the bigger the mobile technology stack it uses. The choice of technologies may depend on the type of the product, its load and security requirements, market deadlines, competition, regulatory concerns, accessibility and affordability of developers, existing team’s knowledge base, available development tools, cost of licenses and support, the target audience’s preferences, the size and age of your company, etc.
