Human Flourishing. Inside Out.
Our mission is to use science to help people take proactive steps to support healthier lifestyles and reduce risk factors for chronic conditions.
To this end, we created 42.
Unlike other health and wellbeing apps, 42 is your personal metabolic health coach.
- Goal-Driven: Your health and lifestyle goals can change over time, and 42 adapts with you.
- Whole-Body Health Approach: Your body works as a system. 42 provides actionable insights with your whole body health in mind.
- Science-Backed: Based on proven evidence from lifestyle medicine, functional health, and circadian science.
- Hyper-Personalized: Analytics and recommendations are based on your own data, not population averages.
You can use 42 even without a wearable. However, with a wearable, you will then be able to take full advantages of 42’s advanced capabilities.
Health Connect Integration
42 integrates with Health Connect by Android to securely access and sync your health data from multiple sources, including Fitbit, Garmin, and other wearable devices of your choice. With your permission, 42 uses this data exclusively to calculate your Daily Optimization Score - an assessment metric that evaluates how closely your daily physical activities, sleep health, and heart rate patterns align with evidence-based standards :
- Physical activities: 42 uses physical activity data (steps, distance, floors climbed, sedentary time, exercise duration, exercise time and exercise intensity) to calculate the Daily Optimization Score. This score provides users with personalized insights on movement and activity balance. Data is not used for any other purpose.
- Sleep health: 42 uses sleep data (total duration, efficiency, and daily sleep patterns) as inputs into the Daily Optimization Score. These metrics help provide personalized insights on recovery, circadian rhythm, and readiness. Data is used only to support this functionality.
- Heart rate activity: 42 uses heart rate data (resting levels, variability, and changes during activities) to calculate the Daily Optimization Score. This helps users understand recovery, activity response, and overall daily readiness. Data is not used beyond this declared purpose.
By integrating these factors, 42 gives you most personalized actionable insights and recommendations to achieve your chosen health goal.
You remain in full control of your data. Permissions can be managed or revoked at any time via your device settings.
