The World’s First Free Health & Fitness Super App
How it works
1
Connect your wearables
Plug in your Apple Watch, Whoop, Oura, or Garmin. Eternal reads what your body has been saying all along.
2
Upload any labs you have
Got bloodwork sitting in your inbox? Upload it. Whether it's from last month or three years ago, Eternal puts it in context and makes it mean something.
3
Tell us about your life
Your goals, your history, your constraints. The more we know about you, the more personalized your care becomes. It all takes less than 5–10 minutes. And it opens up a whole new world.
DESIGN YOUR PERFECT WEEK
Stop guessing. Start living the week your body actually needs
Eternal takes your wearable data, labs, and goals and builds a living plan around them — with training, adaptive tracking, and feedback that keeps up with you.
PERSONALIZED PODCASTS
Your health, in your ears
Not a boring dashboard of numbers. Eternal turns your labs and progress into a personal podcast — with context, education, and interventions that make the data actually mean something.
ETERNAL INTELLIGENCE
A clinical-grade AI that never stops working for you
Ask anything. Get real answers. Eternal Intelligence answers your health, fitness, and aging questions — educates, brainstorms solutions, and watches your wearables so you don't have to.
REAL DOCTORS & COACHES
The team that already knows your story
Every doctor, dietitian, trainer, and coach on Eternal has full context before you even say hello. No repeating yourself. Just care that actually goes somewhere.
ORDER LABS & SCREENINGS
The tests that actually matter. Fully integrated
Blood, hormones, heart, thyroid, cancer screening — ordered, tracked, and interpreted inside Eternal. No more PDFs sitting in your inbox.
IN-PERSON IN NY & SF
Come see us. We'll be ready
Advanced diagnostics, personal training, and physical therapy — in person, in New York and San Francisco. More locations coming soon.
ONE APP. EVERY PART OF YOUR HEALTH
This is what a health super app actually looks like.
Not a tracker. Not a telehealth app. Not a gym membership. All of it — in one place, working together.
Eternal is trusted by thousands
We measure so much more than
leading concierge medicine practices
What I learned about myself with Eternal has been more useful than any testing I had as a professional athlete.

Your body, fully understood.

Strength & Power
How strong are you, really? We measure it — and build a plan around the answer.
