Analysing latest signals
I've reviewed your blood panel and wearable data from this week. Three things stand out:
Key Insights
CRP inflammation marker dropped 18%
HRV trending up — recovery improving
Vitamin D stable — maintain current dose
Your cardiovascular age factor is the biggest remaining opportunity. Adding consistent zone 2 work could shift your biological age by 0.6 years this quarter.

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.

than your chronological age
Your recovery patterns and sleep quality are strong contributors to your lower biological age.
Step One
Discover your biological age
Your chronological age is fixed. Your biological age is a moving target — shaped by how your body actually functions at a cellular and systemic level.
Rewind estimates your biological age by analysing the signals that matter: biomarkers, wearable data, health history, and lifestyle patterns. The result is your Rewind Score — a single, honest number that reveals how fast your body may be ageing.

Step Two
Identify what may be accelerating ageing
Ageing is not random. It is driven by measurable biological systems — inflammation, metabolic health, recovery, cardiovascular fitness, and stress response. Rewind surfaces the specific drivers behind your score so you know exactly where to focus.

Biological Drivers
Inflammation

Cardiovascular
Stress Response
Priority Focus
Cardiovascular signals suggest targeted zone 2 training could improve your ageing profile.
Inflammation
Chronic low-grade inflammation accelerates cellular ageing and tissue breakdown.
Metabolic Health
Glucose regulation, insulin sensitivity, and lipid balance drive metabolic age.
Sleep & Recovery
Deep sleep and recovery patterns directly influence cellular repair and hormone production.
Cardiovascular
Heart rate variability, resting HR, and vascular health shape cardiovascular ageing.
Stress Response
Cortisol patterns and nervous system regulation affect nearly every ageing pathway.
Step Three
Follow a personalised longevity protocol
Rewind does not give you a generic wellness checklist. It builds a targeted protocol designed around the biological signals that are driving your score — and updates it as new data comes in.
Targeted interventions
Every recommendation maps to a specific biological driver. You know why you are doing each thing.
Evolving protocol
As your wearable data, blood work, and behaviours change, your protocol adapts to stay relevant.
Measurable impact
Each task shows its estimated point impact on your Rewind Score, so you can prioritise what matters most.

Rewind Coach
Analysing your latest data
I've reviewed your latest signals. Your inflammation markers have improved since adding omega-3 supplementation. Here's your updated focus:
This Week's Priority
Add 10 min morning sunlight exposure
Increase magnesium to 400mg before sleep
Maintain zone 2 cardio 4x this week
Estimated impact: +4 pts over 30 days
Your cardiovascular score is the biggest opportunity right now. Consistent zone 2 work could shift your biological age by 0.6 years over the next quarter.

Step Five
An AI coach that reads your biology
Your Rewind Coach is not a chatbot repeating generic advice. It reads your wearable trends, biomarker results, and protocol adherence to give you recommendations that are specific to your data — and it updates as your biology changes.
Data-driven insights
Recommendations grounded in your actual signals, not assumptions.
Priority actions
Ranked by estimated impact on your biological age trajectory.
Trend interpretation
Understands what improving — or declining — biomarkers mean for you.
Protocol refinement
Suggests adjustments to your protocol as new data reveals new opportunities.
Step Six
Rewind your ageing trajectory
Biological age is not measured once and forgotten. Rewind tracks how your biology changes over time — and the protocol is designed to move the number in the right direction.

Everything lives inside the app
Your dashboard, protocol, coach, vitals, and tests — all in one place. Here is what the Rewind experience looks like from the inside.
Platform Depth
Built for serious longevity intelligence
Rewind is not a wellness app with a score attached. It is a longevity intelligence platform that integrates diagnostics, wearable signals, biomarkers, AI analysis, and clinical oversight into a single system designed to measure and improve how your body is ageing.
Biomarkers tracked
Lipid panels, inflammatory markers, hormones, metabolic indicators, and more — all linked to ageing.
Wearable integrations
Apple Watch, Oura Ring, Garmin, Whoop — sleep, HRV, activity, and recovery synced automatically.
Longitudinal tracking
Build a health timeline across months and years. Spot trends before they become problems.
Blood Panels
Upload existing pathology or order Rewind-recommended panels through partner labs. Each result feeds directly into your biological age model.
Wearable Data
Continuous data ingestion means your health picture is always current. Sleep, HRV, activity, and recovery flow in automatically.
Health Profile
Detailed intake covering medical history, family history, lifestyle, and goals. This gives the AI a rich baseline understanding of you.
Clinical Review
Longevity-focused clinicians validate your AI-generated protocol and provide clinical oversight at every stage.
Privacy-First
Your health data is encrypted in transit and at rest, stored in a compliant environment, and never sold. You retain full control over your information.

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.
