Key Features

AI-Powered Daily Health Coaching

Luma transforms health information, personal goals, lifestyle patterns, preferences, and previous activity into personalized daily recommendations that help users understand what action to take next. Recommendations can adapt as user behaviour and progress change, giving individuals practical guidance across movement, nutrition, sleep, and mental wellbeing rather than simply presenting health information or static dashboards.

Health Insights & Progress Tracking

The platform brings together health indicators such as activity, sleep, heart-health information, completed actions, and historical trends to give users a clearer view of how their habits and wellbeing are changing over time. Weekly progress summaries combine health information, completed activities, and recent progress into an understandable overview while identifying priorities and recommended actions for the upcoming week.

Personalized Nutrition & Meal Guidance

Luma combines nutrition goals, dietary preferences, activity patterns, calories, and macronutrient information to provide personalized meal plans, recipe recommendations, and contextual nutrition guidance. Users can also log meals naturally through the conversational experience, allowing the platform to understand eating behaviour and provide more relevant recommendations around weight management, healthier eating, and broader wellness goals.

Movement, Sleep & Mental Wellbeing

The platform provides personalized guidance across physical activity, exercise, sleep routines, breathing, relaxation, mindfulness, and stress management, based on each user’s broader lifestyle and wellness context. Guided experiences can include movement recommendations, breathing exercises, sleep-focused activities, journaling, relaxation techniques, and everyday actions that help users improve wellbeing across multiple connected areas rather than treating each one independently.

Conversational AI & Contextual Personalization

Luma includes an AI health-coaching experience where users can ask wellness questions, log health information, record meals, discover recipes, update preferences, and interact naturally with the platform. Each interaction provides additional context around the user’s goals, habits, interests, and behaviour, allowing recommendations and future conversations to become increasingly personalized instead of delivering the same generic guidance to every user.

Connected Health Data & Engagement

Luma connects with Apple Health and Fitbit, combining connected health information with user-entered data, preferences, habits, goals, and progress to create a broader view of personal wellbeing. Challenges, progress tracking, leaderboards, personalized notifications, onboarding, and adaptive recommendations help users remain engaged over time and encourage consistent healthy actions rather than limiting the experience to passive health tracking.

Challenges

1. Turning Health Information Into Meaningful Action

   Users increasingly have access to health metrics, wearable information, reports, and wellness applications, but raw information alone does not clearly explain what they should realistically do next.

2. Personalizing Multiple Areas of Everyday Wellness

   Nutrition, activity, sleep, mental wellbeing, stress, weight, cardiovascular health, and everyday routines influence one another, making static or one-size-fits-all recommendations insufficient.

3. Providing Useful AI Guidance Within Appropriate Health Boundaries

   The platform needed to deliver personalized and practical wellness guidance while maintaining a clear distinction between AI-powered health coaching and professional medical diagnosis or treatment.

4. Maintaining Long-Term User Engagement

   Knowing what to do does not automatically create healthier habits. Users needed ongoing recommendations, progress visibility, challenges, reminders, and feedback to stay consistent over time.

Results & Impact

Luma evolved from an AI-assisted wellness concept into a broader personalized health companion focused on turning health information into everyday action. The platform brings together connected health data, personalized nutrition, movement, sleep, mental wellbeing, stress management, conversational AI, daily recommendations, progress reporting, and behaviour-focused engagement within one connected experience.

Luma created a connected health and wellness experience that helps users move from understanding their health to taking practical everyday action. By combining personalized daily recommendations, conversational AI, nutrition guidance, movement, sleep, mental wellbeing, stress management, connected health data, progress reporting, and engagement experiences, the platform reduces the effort required to interpret fragmented health information and decide what to do next. Its adaptive approach allows recommendations to evolve around each user’s goals, habits, preferences, health context, and previous activity, helping support more consistent wellness behaviours while maintaining appropriate boundaries between AI-powered coaching and professional medical care.
