🎭 Scenario

This mini-challenge focuses on building a simple single-screen interface that displays a user’s activity status in a “Last active” format, showing the moment when the app last transitioned to the background. For simplicity, the app displays the user’s own activity status, while the logic mirrors how another user’s presence is typically shown in real messaging and social apps.

🎭 Scenario

This challenge focuses on building a Moment Journey app that lets users capture and revisit personal moments in a chronological timeline.
