Jetpack Compose is an open-source Kotlin-based declarative UI framework for Android developed by Google. [1] The first preview was announced in May 2019, [2] and the framework was made ready for production in July 2021. [1]
The first preview of Jetpack Compose was announced at the Google I/O conference in May 2019. [2] The developer preview was released in October 2019, [3] and the alpha release took place in August 2020. [4]
Compose entered its beta phase in February 2021, with its first production release taking place that July. [5]
Jetpack Compose supports Android 5.0 and later. [6] It uses the Kotlin programming language, and provides a reactive programming model similar to other UI frameworks such as Vue.js and React Native. [2] Compose is designed to integrate seamlessly with existing Android apps and libraries, allowing developers to gradually convert their apps to Compose. [5]
In Compose, a user interface is defined using functions that have been annotated with the @Composable annotation, which are known as composable functions and define the screen's state. [1] [7] The annotation is used by the Compose compiler to generate the UI boilerplate code. [7]
The 1.0 release introduced Compose Preview, which is built into Android Studio starting with Arctic Fox. It allows composables to be previewed using different configurations without deploying the app to a device. [8]
At the time of Jetpack Compose's 1.0 release, Google said, "There are already over 2,000 apps in the Play Store using Compose – in fact, the Play Store app itself uses Compose." [1] As of October 2022, 160 of the top 1000 apps on the Play Store included Compose. The apps included those from companies such as Airbnb, Lyft and Square. [9]
Google rewrote parts of Android's Settings app using Compose in Android 14. [10] Meta Platforms developed its Threads social media app in five months using Compose. [11] [12]
Compose Multiplatform is a multi-platform UI framework developed by JetBrains and based on Jetpack Compose. It is a port of Jetpack Compose for Windows, macOS, Linux and the web. Version 1.0 alpha was released in August 2021. [1] iOS support was added in May 2023. [13]

Google Contacts is a contact management service developed by Google. It is available as an Android mobile app, a web app, or on the sidebar of Gmail as part of Google Workspace.
The version history of the Android mobile operating system began with the public release of its first beta on November 5, 2007. The first commercial version, Android 1.0, was released on September 23, 2008.
The operating system is developed by Google on a yearly cadence since at least 2011. New major releases are announced at Google I/O in May while still in beta testing with the stable version usually released to the public between August and October.
Dart is a programming language designed by Lars Bak and Kasper Lund and developed by Google. It can be used to develop web and mobile apps as well as server and desktop applications.
Google Play, also known as the Google Play Store or Play Store and formerly Android Market, is a digital distribution service operated and developed by Google. It serves as the official app store for certified devices running on the Android operating system and its derivatives, as well as ChromeOS, allowing users to browse and download applications developed with the Android software development kit and published through Google. Google Play has also served as a digital media store, offering games, music, books, movies, and television programs. Content that has been purchased on Google Play Movies & TV and Google Play Books can be accessed on a web browser and through the Android and iOS apps.
Android Studio is the official integrated development environment (IDE) for Google's Android operating system, built on JetBrains' IntelliJ IDEA software and designed specifically for Android development. It is available for download on Windows, macOS and Linux based operating systems. It is a replacement for the Eclipse Android Development Tools (E-ADT) as the primary IDE for native Android application development. Android Studio is licensed under the Apache license but it ships with some SDK updates that are under a non-free license, making it not open source.
JetBrains s.r.o. is a Czech software development private limited company which makes tools for software developers and project managers. The company has its headquarters in Prague, and has offices in China, Europe, and the United States.
Kotlin is a cross-platform, statically typed, general-purpose high-level programming language with type inference. Kotlin is designed to interoperate fully with Java, and the JVM version of Kotlin's standard library depends on the Java Class Library, but type inference allows its syntax to be more concise. Kotlin mainly targets the JVM, but also compiles to JavaScript or native code via LLVM. Language development costs are borne by JetBrains, while the Kotlin Foundation protects the Kotlin trademark.
Android TV is a smart TV operating system based on Android and developed by Google. It is available on television sets, soundbars, set-top boxes and digital media players. A successor to Google TV, it features a user interface designed around content discovery and voice search, content aggregation from various media apps and services, and integration with other recent Google technologies such as Assistant, Cast, and Knowledge Graph.
Material Design is a design language developed by Google in 2014. Expanding on the "cards" that debuted in Google Now, Material Design uses more grid-based layouts, responsive animations and transitions, padding, and depth effects such as lighting and shadows. Google announced Material Design on June 25, 2014, at the 2014 Google I/O conference.
React Native is an open-source UI software framework created by Facebook Inc. It is used to develop applications for Android, Android TV, iOS, macOS, tvOS, Web, Windows and UWP by enabling developers to use the React framework along with native platform capabilities. It is used to develop the Android and iOS applications at Facebook, Microsoft, and Shopify. It is also being used to develop virtual reality applications at Oculus.
NativeScript is an open-source framework to develop mobile apps on the iOS and Android platforms. It was originally conceived and developed by Bulgarian company Telerik, later acquired by Progress Software. At the end of 2019 responsibility for the NativeScript project was taken over by long-time Progress partner, nStudio. In December 2020 nStudio also oversaw the induction of NativeScript into OpenJS Foundation as an Incubating Project. NativeScript apps are built using JavaScript, or by using any programming language that transpiles to JavaScript, such as TypeScript. NativeScript supports the Angular and Vue JavaScript frameworks. Mobile applications built with NativeScript result in fully native apps, which use the same APIs as if they were developed in Xcode or Android Studio. Additionally, software developers can re-purpose third-party libraries from CocoaPods, Maven, and npm.js in their mobile applications without the need for wrappers.
Fuchsia is an open-source capability-based operating system developed by Google. In contrast to Google's Linux-based operating systems such as ChromeOS and Android, Fuchsia is based on a custom kernel named Zircon. It publicly debuted as a self-hosted git repository in August 2016 without any official corporate announcement. After years of development, its official product launch was in 2021 on the first-generation Google Nest Hub, replacing its original Linux-based Cast OS.
Flutter is an open-source UI software development kit created by Google. It can be used to develop cross platform applications from a single codebase for the web, Fuchsia, Android, iOS, Linux, macOS, and Windows. First described in 2015, Flutter was released in May 2017. Flutter is used internally by Google in apps such as Google Pay and Google Earth as well as by other software developers including ByteDance and Alibaba.
