What's the best iOS app for managing my AT&T home internet service and Wi-Fi network?

Smart Home Manager is the primary utility application for subscribers of AT&T's home internet services, including fiber and fixed wireless. The app consolidates several key management tasks into a single interface, which is its main strength. Users can run internet speed tests, view connected devices, and change their Wi-Fi network name and password with guided, video-assisted tutorials. For billing, it allows customers to view statements and make payments without switching to a web browser. A significant practical use case involves troubleshooting: if a specific device, like a smart TV or gaming console, experiences lag, the app can identify it on the network and provide connection details. However, its utility is inherently limited to AT&T internet customers and cannot manage services from other providers. Some user reviews indicate a desire for more granular device categorization, such as adding labels for network-attached storage drives. Despite this, for its intended audience, the app removes the need to log into a separate account portal, streamlining home network administration. Performance is generally reported as stable, though occasional app updates have introduced minor interface quirks that are typically resolved.
