HarmonyOS 2 billion devices 2023

HarmonyOS is currently ruling as the China-exclusive (majorly) operating system and Huawei is looking to install HarmonyOS in 2 billion devices by 2023.

Yes, the aim is quite big but if we look into the progress that this software has made over the past three years, the company has already achieved many milestones that we can’t ignore.

How?

Let’s dive into the past installations, Huawei achieved over 200 million installations by the end of 2021 but it was only for Huawei devices. Meanwhile, HarmonyOS Connect, an operating system for third-party company products, launched 100+ million fresh devices with HarmonyOS pre-installed.

Moving to 2022, Huawei posted a heavy 320 million HarmonyOS installation mark in its own devices, and then HarmonyOS Connect launched with 250+ million third-party products.

Stepping further, OpenHarmony, an open-source version of HarmonyOS has also come so far to show its worth in the tech industry and made rapid growth in the last two years after its submission to OpenAtom open-source foundation.

The combined weight of HarmonyOS for Huawei devices and HarmonyOS Connect stands above
570 million devices, which is the biggest single-year growth made by any operating system. However, the actual number may have been around 700 million.

2023:

This year, Huawei may expand HarmonyOS in the global market and launch new products. On the other hand, HarmonyOS Connect could surpass the biggest figure, which seems more exciting.

According to inputs, OpenHarmony could post new records, as it’s used by various major Chinese tech players to use for different purposes. With all of these combined, HarmonyOS could successfully aim at 2 billion devices by the end of 2023.

In near future, HarmonyOS will continue to evolve based on the declarative development system and the three major concepts to develop the HarmonyOS application ecosystem in all aspects.

Huawei switched the declarative development system end-to-end from design > development > testing > launch, and upgraded the application development kit to the “HarmonyOS Development Kit”.

The HarmonyOS development kit also includes a complete application development and operation system: Design system, development language, UI system, compilation tools, development tools, testing services, and on-shelf distribution.

HarmonyOS Design covers comprehensive full-scenario design specifications, rich design resources, and design tools to help developers improve development efficiency.

ArkTS is the development language for HarmonyOS ecosystem applications. Based on TypeScript (TS for short), it provides corresponding capabilities such as declarative UI and state management, allowing developers to develop high-performance applications in a more concise and natural way.

ArkTS is a more concise and efficient JS/TS language “superset”, which further reduces the amount of cross-terminal application development code and improves development efficiency by 30%.

ArkTS provides a concise and efficient declarative development paradigm by extending mature languages ​​and combining grammar support for ArkUI. Combined with the design of UI components, state management, and other aspects, it unifies the development paradigm of HarmonyOS ecological applications.

ArkUI Framework ArkUI is the native UI development framework of the HarmonyOS ecosystem. The ArkUI rendering mechanism upgrade, the unique rendering three-tree integration technology, greatly simplifies the interface rendering algorithm and increases the sliding loading speed of the application interface by 45%.
