Upload the labs your doctor already orders. We calculate your PhenoAge — a peer-reviewed estimate of biological age — and track it across every test you take. No new blood draw. No supplements to sell you. Just signal.
Upload a Quest or Labcorp PDF and we extract the nine biomarkers PhenoAge uses. Or type them in by hand. Either way, you get your biological age in under a minute.
Every test you add becomes a point on a chart. See whether you're aging faster or slower than the calendar, and watch what changes when you change something.
Each test breaks down which biomarkers are making you look older or younger than your chronological age — and links to the peer-reviewed evidence on what they reflect.
PhenoAge is a biological age estimator developed by Morgan Levine and colleagues in a 2018 peer-reviewed study, validated against mortality outcomes in the NHANES dataset.
It uses nine biomarkers that come standard on a complete blood count, comprehensive metabolic panel, and C-reactive protein test — the labs most adults already get at their annual physical.
We didn't make this up. We didn't license it from a startup that won't show its work. The algorithm is open, the paper is public, and you can verify the math yourself.
Upload a PDF from Quest or Labcorp and we parse it automatically. Or punch the numbers in yourself — there are only nine.
Get your PhenoAge, the delta against your chronological age, and a breakdown of which biomarkers contributed most.
Add your next test in three months, six months, a year. Watch the trend. Note what changed in your life. Repeat.
Calculate your PhenoAge once. Keep the result. Decide if it's useful before you pay.
For people who get tested more than once. Which is the only way this question gets interesting.
We're launching later this year. Sign up and you'll be first in, with 30% off your first year. No spam. No newsletter you didn't ask for. Two emails, max, before launch day.
PhenoAge is a biological age estimator published by Morgan Levine and colleagues in 2018 (peer-reviewed, in the journal Aging). It takes nine standard blood biomarkers and produces a number that estimates how old your biology looks, statistically speaking, compared to a reference population. It's been validated against mortality and disease outcomes. It is not a diagnosis. It is not a medical device. It's a research-grade signal that, tracked over time, can tell you whether your trajectory is moving in the direction you want.
No new blood draw is needed if you already get an annual physical. The nine biomarkers PhenoAge uses (CBC, CMP, and CRP) are some of the most commonly ordered tests in primary care. Pull your last lab report from your doctor's portal, Quest's MyQuest, or Labcorp's portal, and upload it. If your doctor doesn't order CRP, you can add it for around $20 at most direct-to-consumer lab services.
Function and InsideTracker sell you the blood test ($300–$500+) and use proprietary scoring. Tally and TruDiagnostic use epigenetic methylation clocks, which require their own specialized test kits. We don't sell labs. We don't ship kits. We take the bloodwork you already have, run a peer-reviewed open algorithm on it, and help you track the result. We're an order of magnitude cheaper because we're doing an order of magnitude less. That's the point.
No, and we won't pretend otherwise. PhenoAge is an educational tool and a research-validated estimate. We don't diagnose, treat, or prevent any disease. We don't tell you to take supplements. If your biomarkers look unusual, talk to your doctor — they ordered the test in the first place. Our terms of service say all of this in more legalese.
We store the nine biomarker values you give us and the dates of the tests. That's it. We don't keep the original PDF after parsing it. We don't share or sell your data to anyone, ever — not advertisers, not data brokers, not "research partners." You can export everything as a file, or delete your account and all associated data, anytime, from your settings. We are not a HIPAA-covered entity (we're a consumer wellness tool, not a healthcare provider), but we treat your data with at least that level of care.
A small team. Right now, very small. We're not VC-backed. We're not chasing a billion-dollar exit. We want to build a useful tool that pays for itself, treats users like adults, and stays around for a long time. If that resonates, you're in the right place.
