Why is Centenary Day free?

Longevity should be for everyone

We believe that everyone should have access to the tools and knowledge needed to live a longer, healthier life. That's why we offer Centenary Day for free.

Our mission is to democratize health optimization and longevity science, making it accessible to all, regardless of financial means.

By providing our platform at no cost, we aim to empower individuals to take control of their health and well-being, fostering a global community focused on living better and longer.

A bigger mission than profit

We didn’t start Centenary Day just to build another subscription app. We started it because longevity science is moving faster than most people can keep up with—and the gap between what’s known and what’s practiced is costing lives. By offering a free plan, we lower the barriers for anyone to:

Learn the fundamentals of evidence-based longevity practices.
Build sustainable habits without feeling overwhelmed.
Experience how much easier health can be when you have the right tools.

Free doesn’t mean less important

Many companies treat their free users as an afterthought. We don’t. Our free plan includes core features to help you design your healthiest life:

Personalized routines with science-based recommendations.
A meal plan tailored to your goals.
The ability to track your progress and stay accountable.

It’s everything you need to get started on your journey as a Next Generation Centenarian.

How we keep the lights on

You might be wondering: how can we offer so much value for free?

Our business is designed to grow sustainably by offering optional paid plans for users who want:

Unlimited routines and meal plans.
Advanced customization and tracking.
Family features and shared planning.
Priority support.

When you choose a paid plan, you’re not just investing in your own health—you’re helping us keep the core of Centenary Day free for everyone.

We think of it like this: our community funds our mission together.

Why it matters

The future of health belongs to those who take action today. But too often, the biggest barrier isn’t knowledge — it’s access.

That’s why we’re committed to keeping a robust free version of Centenary Day forever. So you can start building better habits now, without worrying about cost.

Because health optimization should be a basic right, not a luxury.

Join us

Whether you stay on our free plan forever or decide to unlock even more features later, you’re part of a movement redefining what’s possible for human longevity.

Your journey to living beyond 100 starts here — and it starts free.
