Programs Built on Real Data
LLIF programs are longitudinal experiences that combine structured tracking, personal insights, and — where participants choose — real-world data that advances collective understanding.
Join a community study. Subscribe to a program from an expert you trust. Or build one of your own.
Community Research Programs
Open-enrollment longitudinal studies on topics that matter to millions of people. Participants track their own data, receive personal insights, and — with consent — contribute to research that benefits everyone.
Community Allergy Study
Track respiratory symptoms alongside 25+ environmental factors — AQI, pollen counts, humidity, barometric pressure, and local weather — over a full allergy season. Discover your personal triggers. Contribute to population-level understanding of how environmental conditions drive symptoms across regions and demographics.
You learn what drives your symptoms. Researchers learn what drives everyone's.
Join the Waitlist →VO2 Max & Cardiovascular Fitness Study
A longitudinal study tracking cardiorespiratory fitness over time across a diverse participant community. Log workouts, sync wearable data, and track the lifestyle factors that correlate with VO2 max improvement or decline. Participants receive longitudinal fitness insights. Researchers build population-level understanding of what actually drives cardiovascular health.
Personal performance tracking. Collective fitness knowledge.
Join the Waitlist →Migraine Triggers & Patterns Study
A participant-driven longitudinal study tracking migraine frequency, severity, and triggers across a large community. Log attacks, symptoms, medications, and outcomes. Track potential triggers: sleep, nutrition, hormones, weather, stress, and screen time. Discover your personal patterns and contribute to the largest real-world migraine dataset built from participant-owned data.
Understand your migraines. Help others understand theirs.

Real longitudinal data
Programs collect continuous, structured data over weeks and months — not one-time surveys. Patterns invisible at a single point in time become visible across a season, a year, a lifetime.
Insights back to every participant
Every participant receives personal insights from their own data. Programs deliver value, not just data collection. That's why participants stay enrolled — and why the data stays high quality.
Participant-owned, always
Data belongs to participants. They consent to share it with program organizers. They can export or delete it at any time. No extraction. No resale. Structural guarantees, not policies.
