Meet Indigo
A companion,
not a robot.
Indigo runs on state-of-the-art AI models, but it doesn’t talk like a chatbot. It talks like a friend who’s genuinely in your corner. It keeps you honest without the guilt trips.
Remembers what matters to you
Your goals, your routine, the knee that's still healing. Indigo keeps the context so you never have to repeat yourself.
Checks in at the right moments
A nudge in the morning, a reflection in the evening, timed to your schedule. Never a wall of notifications.
Adapts when life changes
Busy week, holiday, injury. Indigo adjusts your habits with you, and can add, pause or drop them right from the chat.
Private by design
Your conversations with Indigo are encrypted, and your data is never sold.
How it works
Small habits.
Real momentum.
- 01
Tell Indigo about you
A two-minute check-in on your sleep, movement, food and stress gives you a starting lifestyle age and a habit plan that fits your life.
- 02
Check off your day
Tap through your habits in seconds, or let Apple Health and Health Connect fill in steps, sleep and workouts for you.
- 03
Watch the trend
Your habit score, streaks and rate of aging update as you go, so you can see which habits are really paying off.
Rate of aging
See your habits add up to years.
Every habit you log feeds two numbers: your rate of aging, where 1.00× is average and lower is better, and your lifestyle age, how old your habits make you look on paper. Good weeks pull them down. You’ll see it happen.
- Rate of aging
- 0.96×
- Lifestyle age
- 42.6−1.4

FAQ
Questions, answered.
What is Indigo?
Indigo is an AI longevity and habit tracker for iPhone and Android. It helps you build small daily habits across sleep, hydration, movement, nutrition and mind, with an AI companion that knows your routine and checks in every day.
What is rate of aging?
Your rate of aging is a score based on the habits you log. 1.00× is average and lower is better, so a good week of sleep, movement and nutrition pulls it down. It's an estimate based on lifestyle factors, not a clinical measurement.
What is lifestyle age?
Lifestyle age is how old your habits make you look on paper. You get a starting lifestyle age from a two-minute check-in, and it moves as your habits change.
How does the AI companion work?
Indigo runs on state-of-the-art AI models and talks like a friend, not a chatbot. It remembers your goals and routine, checks in at the right moments, and can add, pause or drop habits right from the chat when life changes.
Is Indigo free?

Does Indigo work with Apple Health and Health Connect?
Yes. On Premium, Indigo reads the steps, sleep and exercise duration you approve from Apple Health or Health Connect and checks those habits off for you. Access is read-only.
Is my data private?
Your conversations with Indigo are encrypted, and your data is never sold. You can request a copy or deletion of your data at any time.
Is Indigo a medical app?
No. Indigo is a wellness app, not a medical device, and doesn't provide medical advice.
