Most platforms stop at data. Rewind executes. It turns your biology into a precise daily Protocol, continuously updated as your biology evolves. The world's first closed-loop system for reversing biological age.
Your body is either
ageing or reversing.
Most people don't know which.

Healthcare waits until
you're already broken.
We test you before that happens.

Your inflammation markers (CRP, IL-6) are elevated. This is likely driven by poor sleep recovery and high cortisol. Prioritise magnesium and cold exposure this week.

Rewind doesn't track your health.
It runs it.
One closed loop. Always adapting.
Connect. Protocol. Improve.
Connect your biology.
Blood panels, wearables, DNA, health history. Rewind ingests every signal and builds a complete biological picture.
Get your Protocol.
AI analyses your biology, finds what matters most, and builds a personalised Protocol: what to take, what to do, and what to avoid.
Your biology improves.
Your Protocol updates as your body changes. Every quarter, your data recalibrates the system. The loop never stops.
Six systems. One unified score.
We test your biological markers across six core systems to build the perfect Protocol for your body. Without data, it's guesswork.

Your wearable collects data.
Rewind makes it useful.
We connect to 70+ devices and platforms. Every signal feeds your biological age and Protocol.
Built from
your biology.
Not a quiz. Not a questionnaire. Rewind builds your Protocol from real biomarkers, real wearable data, and real genetics. Two people with identical goals get completely different protocols.
Because your biology isn't generic.
100+ biomarkers
Blood, DNA, epigenetics — your full biological picture

Common questions
How it works
Your Rewind Score is a single number that captures your overall biological health. It's calculated from your blood biomarkers, wearable data, and lifestyle factors — updated continuously as new data flows in.
Start with a free 2-minute assessment. For a precise result, connect your wearable or upload blood panel results. The more data Rewind has, the more accurate your biological age estimate becomes.
Our comprehensive panel covers 100+ biomarkers across six body systems: cardiovascular, metabolic, hormonal, cognitive, immune, and recovery. This includes ApoB, HbA1c, hs-CRP, testosterone, vitamin D, and many more.
We recommend quarterly blood panels to track trends over time. Your wearable data streams in daily, so your Rewind Score updates continuously between blood draws.
No — wearables enhance your data but aren't required. You can start with blood panels alone. We support Apple Watch, Oura Ring, Whoop, and Garmin when you're ready to connect.
Membership & pricing
Everything: your Rewind Score, biological age tracking, AI Coach, doctor-reviewed protocols, wearable integration, quarterly progress reports, 100+ biomarker tracking, and personalised supplement recommendations.
Yes. There are no lock-in contracts. Cancel your membership at any time and retain access until the end of your billing period.
No. Rewind complements your existing healthcare. Our longevity-focused clinicians review your results and provide guidance, but we always recommend maintaining your relationship with your primary care provider.
Wearable data syncs in real time. Blood panel results are typically available within 3–5 business days after your draw, with doctor-reviewed interpretations following shortly after.
Your body is ageing right now.
The question is
how fast.
