Track How You Live. Not Just What You Do.
VivaLyn Sathi doesn't just count steps or calories. It measures seven dimensions of your wellbeing — from emotional stability to social connection — and computes a personalised longevity score that tells you how you're really doing. All from a 30-second daily voice check-in.
Seven Dimensions, One Score
Your longevity score is computed on-device using weighted contributions from seven areas of wellbeing. No health data leaves your phone — ever.
Eight Moods. Your Emotional Timeline.
Log your mood in a tap — or let Sathi detect it from conversation. Over time, your emotional timeline reveals patterns that help you understand yourself better.
Happy
Calm
Neutral
Stressed
Sad
Angry
Anxious
Excited
Wellness That Actually Fits Your Day
30-Second Daily Check-in
Swipeable cards capture your mood, sleep hours, water intake, and exercise minutes. Or just say it: "I'm feeling happy, slept 7 hours, had 5 glasses water, walked 30 minutes." Done in half a minute.
7-Dimension Longevity Score
A personalised score from 0 to 100, computed across emotional stability, routine consistency, social connection, cognitive activity, stress management, sleep regularity, and physical activity. Weighted by health impact.
Streaks & Milestones
Build consistency with daily check-in streaks. Hit 7 days, 30 days, 100 days. Twenty-two milestones to unlock. It's a simple game, but it works — people who track daily actually feel better over time.
AI Wellness Insights
Sathi spots patterns you'd miss: exercise days lead to better mood. Poor sleep correlates with afternoon stress spikes. Insights drawn from your own data, never generic advice.
Mood Auto-Capture
During casual conversations, Sathi detects your emotional state and logs it automatically. Rate-limited to once every 30 minutes, so it doesn't oversaturate. Your emotional timeline builds naturally.
Correlation Engine
An on-device engine analyses relationships between your wellness dimensions. Does walking improve your sleep? Does journaling reduce stress? Sathi finds the answers from your patterns.
