An atomic service is an innovative service form in HarmonyOS.
- Differences between atomic services and apps: Atomic services are free from download, installation, and login, and can be fully released and used immediately after being started. Atomic services support AI distribution and achieve lower customer acquisition costs than apps.
- Differences between atomic services and widgets: HarmonyOS displays service information through widgets, enabling users to efficiently view important information about atomic services or apps on the home screen.
- Differences between atomic services and applets: Running based on the HarmonyOS framework, atomic services can be exposed through more shallow entries and deeply combined with the system, to provide richer interaction experiences across scenarios. You can develop one set of code and deploy it on multi-devices including HarmonyOS PCs/2-in-1 devices, tablets, telematics devices, and more.
