What is a tech stack?

A tech stack combines programming languages, frameworks, libraries, tools, and infrastructure developers use to build and deploy software applications. It represents the layers and components that work together to create an application’s underlying architecture and functionality.

A typical tech stack for web development, for example, may include a combination of front-end technologies like HTML, CSS, and JavaScript, along with back-end technologies such as a programming language (e.g., Python, Ruby, or Java), a web framework (e.g., Django or Ruby on Rails), and a database (e.g., MySQL or PostgreSQL).

A tech stack for a mobile development company, on the other hand, will include a combination of tools specifically designed for developing and deploying artificial intelligence solutions.

Developers need a tech stack to streamline the development process, leverage existing tools and libraries, and enhance productivity. A tech stack provides a standardized foundation that developers can build upon, reducing the need to reinvent the wheel for common functionalities. It allows for efficient collaboration among team members, as everyone can work with the same set of technologies and understand the overall architecture.

The second part of this stack is the iOS Software Development Kit, which includes libraries for user interface design, device functionality access, networking, and more.

Use Swift + iOS SDK to create iOS apps with exceptional performance, native look and feel, and seamless integration with Apple's ecosystem. This combination allows for efficient memory management, robust error handling, and extensive access to platform-specific APIs, resulting in high-quality, responsive, and feature-rich iOS apps.

Kotlin + Android SDK

Kotlin is a modern programming language with concise syntax, null safety, and enhanced developer productivity. Developed by JetBrains, it is fully interoperable with Java. The Android Software Development Kit (SDK) adds a rich set of tools, libraries, and APIs for Android app development and offers features for UI design, data storage, networking, multimedia, etc.

Kotlin + Android SDK has become an alternative to Java for Android app development. With Kotlin, reading, writing, and maintaining code is much easier. It offers modern language features like coroutines for asynchronous programming, extension functions for enhancing existing APIs, and type inference for reducing verbosity.


On the other hand, cross-platform or hybrid app development frameworks allow you to build apps that can run on multiple platforms using a single codebase. These frameworks have specific tech stacks, which may include a combination of JavaScript, native bridge, and UI libraries.

Ionic + HTML/CSS/JavaScript

Ionic is an open-source framework built on top of Angular and Apache Cordova with a library of UI components, tools, and services that facilitate the development of hybrid mobile apps, while HTML/CSS/JavaScript are used to create the user interface and logic of the app.

This stack helps create hybrid apps with a native-like appearance and performance. You can create visually appealing and responsive interfaces using Ionic's UI components and themes. The apps are then wrapped in a native shell using Apache Cordova, which provides access to device features like camera, geolocation, and notifications.

React Native + Ionic

In this tech stack, React Native allows you to build native-like mobile apps using JavaScript and React. Ionic is used alongside React Native to provide additional UI components and tools, enhancing the development process. The result is hybrid apps with a highly performant and native user experience.

React Native compiles JavaScript code to native components, resulting in faster execution and smoother animations. By integrating Ionic with React Native, you can use Ionic's UI components and services, creating visually appealing and consistent interfaces across platforms.


Mobile app tech stacks for cross-platform development employ frameworks that allow developers to write code in a common language, which is then compiled or interpreted to produce native-like experiences on various platforms.

React Native+JavaScript

React Native + JavaScript enables you to build mobile apps that deliver native-like performance and user experience across platforms. You first write code in JavaScript, and then React Native compiles it to native components.

This approach allows for code reuse, resulting in faster development cycles and reduced maintenance efforts. React Native, in this combo, provides a vast ecosystem of community-driven libraries and plugins that enhance functionality and accelerate development.


You can also utilize Flutter to build cross-platform apps with a visually rich user interface and high performance. It offers a comprehensive set of widgets that deliver a consistent experience across platforms, for example, a layered architecture, allowing for a customizable and flexible UI.

With Flutter's hot-reload feature, you can see instant changes to the app during the development process, improving productivity and iteration speed. Flutter's Dart language provides a modern and expressive syntax, making code development and maintenance efficient.
