Healthspan coach for men 50+
Your doctor gets a report,
not a black box.
BackNine reads the Apple Watch or Oura ring you already own — plus your labs, meds, and blood pressure — shows its math, and tells you what today is buying you in quality years.
Free at launch. Works with the Apple Watch you already own, or Oura. No ads, no data sales.
Built by David B., 58, for his own foursome — and run on his own numbers every morning.
The doctor layer
Show up prepared to every visit.
Blood pressure history. Labs with reference ranges. Current meds. Recent symptoms. A one-page PDF you can email your doctor or bring to your next appointment — the summary they actually want to see.
📄
Doctor Report
One-page PDF summarizing your BP, sleep, weight, and lab trends. Print it, email it, share a private link.
🩺
Visit Prep Mode
Two weeks before your appointment, we help you draft the questions worth asking based on what your data shows.
🚨
Clinical Flags
Sustained blood pressure over 140/90? We surface it here and in the report. No opinions — the numbers, sourced.
Longevity is a team sport
Bring your foursome.
Invite your spouse, workout partners, or the guys you tee off with Saturday. A weekly league, a Sunday scoreboard, and a coffee tab for whoever finishes last. People quit alone. Nobody quits the week the coffee’s on them.

Scored on sleep, movement and consistency — not on which gadget you own. Lowest score buys the coffee.
The fair question
Why not just use the Oura app? Or Apple Health?
Use them — we do. They tell you how you slept and how recovered you are today, and they’re getting better at it every year. BackNine does three things they can’t:
Your foursome, played net
A weekly league your friends can join from any watch or ring — scored like golf, against your own par, so the fit guy and the guy getting started play the same game. Lowest net buys the coffee.
Every score, with the math
Tap any number and see what moved it. Your ring's app tells you a score; we show you the work, and we'll say out loud when we're not sure.
Years, not days
Readiness is about this morning. Your Health Span score, Biological Age and QYL Index are about the next twenty years — and they move when your habits do. The doctor report is the receipt.
If all you want is a prettier recovery dashboard, there are good free ones. That’s not this.
Show your math
Every score, sourced.
Biological Age, Health Span, the QYL Index — none of them is a black box. Tap any score to see which markers rolled up, how each one moved the number, and how recent the data is. The full methodology is public: how we score you. If we’re not confident, we say so.
