Recently, Tesla, the global leader in new energy vehicles, officially launched its exclusive App compatible with HarmonyOS, making a full entry into Huawei's app market. The App provides HarmonyOS users with comprehensive functions such as remote vehicle control, vehicle management, and charging services. While this event may seem like a routine collaboration between automakers and mobile ecosystems, it sends a strong industry signal: As China’s first truly scalable and globally competitive independent operating system, HarmonyOS has never been a niche player. With the continuous expansion of its device base, its massive user volume has attracted overseas enterprises to proactively adapt and participate in co-construction, evolving from a local benchmark to the world’s third-largest mobile ecosystem alongside iOS and Android. This marks the definitive end of the long-standing absence of a credible domestic operating system in China.

Tesla App Launches on HarmonyOS Devices

Before the advent of HarmonyOS, China’s operating system domain had long been in an awkward state of 'vacancy and dependence'—key areas such as consumer-grade and industrial-grade systems were almost entirely monopolized by foreign systems. Whether in mobile devices like smartphones and tablets or IoT devices like in-vehicle systems and smart home appliances, Android and iOS held absolute dominance. Domestic companies mostly engaged in superficial optimizations based on foreign underlying frameworks, lacking autonomous control over core technologies. This not only exposed them to the risk of being 'technologically constrained' but also hindered the construction of a digital ecosystem for China. At that time, a few domestic operating systems attempted to break through but ultimately failed due to immature technology, incomplete ecosystems, and insufficient user bases, remaining marginal products unable to compete with foreign systems. For a long time, China faced the dilemma of having no substantial independent system available.

The emergence of HarmonyOS has completely broken this deadlock. As a distributed operating system independently developed by Huawei, HarmonyOS was positioned from the outset as 'all-scenario and autonomously controllable,' freeing itself from reliance on foreign underlying code while building a core advantage of 'develop once, deploy across multiple platforms.' It supports a full range of terminals including smartphones, tablets, watches, smart screens, in-vehicle systems, and smart home devices, filling the gap in China’s lack of a mature independent operating system. Unlike previous domestic systems that faded quickly, HarmonyOS has maintained rapid iteration since its launch—from HarmonyOS 1 to the current HarmonyOS 6. Each version has achieved breakthroughs in technical optimization, ecosystem improvement, and device compatibility, gradually constructing an ecosystem with core competitiveness. From the beginning, HarmonyOS stood at a non-niche starting point, advancing toward scale and globalization.

Tesla’s proactive development of a HarmonyOS-compatible app essentially represents dual recognition of the market scale and ecosystem value of HarmonyOS devices. In the mobile internet industry, the prosperity of an application ecosystem directly depends on the base number of terminal devices. Whether overseas brands are willing to invest resources in adapting to a new system hinges on user coverage and commercial return potential. Previously, overseas brands primarily focused on iOS and Android—not because HarmonyOS was inferior, but because its ecosystem was still in a rapid growth phase. Now, Tesla’s active participation indicates that the device volume and commercial value of HarmonyOS have met the core expectations of top international enterprises. It is no longer an 'optional choice' but a critical platform that must be prioritized for accessing the Chinese market and engaging with a massive user base.

The core supporting this transformation is the leapfrogging breakthrough in the number of HarmonyOS devices—a key factor that has kept it from becoming a niche system. As of March 2026, He Gang, CEO of Huawei Terminal BG, officially disclosed at the spring all-scenario product launch event that the number of terminals running HarmonyOS 6 and the pure-blood HarmonyOS devices had exceeded 50 million, with daily growth exceeding 150,000 units. By early April 2026, this figure had surpassed 51 million.

The 50-million-device threshold is a critical watershed for an operating system ecosystem transitioning from 'steady development' to 'comprehensive prosperity,' and HarmonyOS has long since crossed this milestone, forming a positive cycle of 'user base—developer investment—application supply.' Currently, the number of registered developers in the HarmonyOS ecosystem has surpassed 10 million, offering over 350,000 apps and services covering scenarios such as travel, office work, entertainment, and smart homes. The application ecosystem has shifted from 'addressing shortcomings' to 'building differentiated advantages.' Unlike previous domestic systems that garnered praise but lacked traction, HarmonyOS leverages Huawei’s technological foundation and all-scenario compatibility capabilities to rapidly achieve large-scale deployment across the Mate, Pura, and Nova series models, as well as in-vehicle systems and IoT devices. Non-smartphone devices account for 30% of its ecosystem, with both breadth and depth of user coverage continuously expanding, maintaining the development momentum of a mainstream system.

Counterpoint Research Data

From an industry perspective, the global mobile operating system market has long been dominated by Android and iOS, which together account for over 95% of the market share, leaving little room for other systems to break through. However, the rise of HarmonyOS is disrupting this entrenched landscape. According to data from research firm Counterpoint Research, HarmonyOS holds a market share of 18.6%, surpassing iOS to firmly secure second place domestically and establishing itself as a mainstream player. HarmonyOS has become the world’s third-largest mobile ecosystem. More notably, as its device volume continues to grow, overseas enterprises have begun proactively developing HarmonyOS-compatible products, with Tesla being just one example. Currently, multiple international consumer electronics brands and internet application vendors have initiated HarmonyOS product development, actively contributing to the co-construction of the HarmonyOS ecosystem.

The active participation of overseas manufacturers marks the completion of HarmonyOS’s transition from 'independent construction' to 'global recognition,' affirming its non-niche positioning. In the past, the construction of the HarmonyOS ecosystem relied more on domestic vendor collaboration and Huawei’s own efforts. Today, the vast installed base of devices and clear paths to commercial monetization have attracted international capital and technical forces to join proactively, transforming ecosystem expansion from 'unilateral advancement' to 'multi-party co-construction.' This shift not only enhances the richness of applications and the completeness of user experience within HarmonyOS but also establishes the technological image and commercial value of domestic systems on a global scale, breaking overseas prejudices against China’s independent operating systems.

For the entire Chinese technology industry, the rise and development of HarmonyOS carries significance far beyond the system itself. It not only ended the history of China lacking a decent self-developed operating system but also enabled the country to finally possess an independently developed operating system with global competitiveness, breaking the long-term monopoly of overseas systems in fundamental technologies and ecosystem rules. In the new era of intelligent vehicles, smart homes, AI terminals, and the Internet of Everything, the operating system is the core foundation of the digital economy. With its full-scenario distributed advantages, HarmonyOS has not only established a strong foothold in smartphones but also taken the lead in areas such as automotive systems and IoT, providing independent and controllable foundational support for the domestic technology industrial chain. This pushes China’s technological advancement from hardware manufacturing toward software ecosystems and system-level upgrades, enhancing its influence in the global industrial chain.

In the future, as the number of HarmonyOS devices continues to grow rapidly and its ecosystem matures, the gap between HarmonyOS, iOS, and Android will further narrow. When more overseas enterprises consider HarmonyOS a core strategic market, when developers prioritize optimizing experiences for HarmonyOS, and when users adopt HarmonyOS as their preferred system, it will have truly transformed from a local mainstream system to a globally competitive one, forming a tripartite balance with iOS and Android.

Tesla's adaptation of HarmonyOS is merely a landmark footnote in this historical process. The broader trend is that HarmonyOS, as China’s first mature self-developed operating system, has never been relegated to niche status; it has now crossed the critical threshold of scale and entered a phase of rapid growth, securing an irreplaceable position in the global technology ecosystem. A new intelligent terminal ecosystem led by China and co-constructed globally is taking shape, reshaping the global digital industry landscape while laying a solid foundation for the independent and controllable development of China’s technology industry.
