Luminary
Inspiration
Luminary is an app designed to support individuals, especially international students, by promoting mental wellness and ensuring safety. The app provides a private, low-pressure space where users can track their emotions daily, with no social interaction required.
A key feature is the Journal, where users capture their feelings and select a "Mood Sprite" in different colors. Google Gemini powers personalized, empathetic responses to each entry, transforming journaling from a solitary activity into a supportive dialogue.
Users can review past entries through a calendar view to track emotional patterns. Safety features include emergency contacts who are notified if check-ins are missed, with the ability to pause check-ins at any time.

- Daily journaling with colorful Mood Sprites
- AI-powered warmth via Gemini's personalized reflections

- Safety check-ins with emergency contact notifications
