Design an app for Meta's smart glasses.

Focus on the unique capabilities and limitations of smart glasses, such as augmented reality features, voice commands, and hands-free interaction. Consider the target user demographic and their specific needs—whether for social interaction, productivity, or entertainment. Think about how the app can leverage the glasses' features to enhance user experience, such as integrating with social media or providing real-time information overlays. Be prepared to discuss user interface design, potential use cases, and how the app can differentiate itself in the market.
