Healthy longevity is your capital. Invest daily. Vested for life.
The invisible cost
In the U.S., the gap between how long people live and how long they stay healthy is about 12.4 years — the largest of 183 countries.
Daily habits — sleep, movement, smoking, drinking, stress — shape that gap. But day to day their effect is invisible, until it shows up decades later. Dayvest makes it visible today.

How it works
Your health, as a balance sheet
Log your day
Sleep, activity, nutrition, smoking, alcohol, stress, social connection — tap what applies. About a minute a day.
See the deposit — or the withdrawal
Every habit becomes days of healthy life gained or lost. Your total is your health capital.
Watch your capital grow
Follow the trend by week, month and year. “What if…” shows what a change would be worth before you make it.
Our principles
Numbers, not noise
Built on research
Every factor is grounded in peer-reviewed studies. Sources are in the app’s Knowledge Base.
No guilt, no lectures
A bad day is just a withdrawal. Tomorrow is another chance to invest.
Motivation, not diagnosis
Dayvest gives a statistical estimate to keep you going. It is not medical advice and doesn’t replace your doctor.
