How It Works
Your path to a longer, healthier life
Rewind turns complex health data into clear, actionable plans — reviewed by real clinicians and refined over time. Here is exactly how the process works, from your first sign-up to ongoing longevity care.
Your Journey
Seven steps to optimised longevity
From sign-up to ongoing care, every stage of the Rewind process is designed to be simple, thorough, and clinician-backed.
Create Your Account
Sign up and choose a membership plan that aligns with your health goals. Whether you are focused on general wellness, athletic performance, or comprehensive longevity care, there is a plan built for you. Onboarding takes less than five minutes.
Complete Your Health Questionnaire
Answer a detailed intake questionnaire covering your medical history, lifestyle habits, sleep patterns, stress levels, diet, and health goals. This gives our AI a rich baseline understanding of who you are and what matters to you.
Connect Your Data Sources
Link your wearable devices — Apple Watch, Oura Ring, Garmin, Whoop, or others — and upload any existing blood work or diagnostic results. The more data we have, the more accurate and personalised your insights become.
AI Analysis & Biological Age
Our AI engine analyses your full health picture — biomarkers, wearable metrics, questionnaire responses, and medical history — to calculate your Biological Age and identify key areas where targeted interventions may help improve your long-term health outcomes.
Personalised Longevity Plan
Based on your analysis, Rewind generates a tailored health plan covering nutrition, supplementation, exercise programming, sleep optimisation, and stress management. Every recommendation is grounded in your unique data and designed to support measurable improvement.
Doctor Review & Refinement
A longevity-focused clinician reviews your AI-generated plan, validates the recommendations, and adjusts anything based on their clinical expertise. This human oversight layer ensures your plan is safe, appropriate, and aligned with best medical practice.
Ongoing Tracking & Optimisation
Health is not a one-off event. Rewind continuously monitors your wearable data, prompts regular blood work, and updates your plan as new information comes in. Over time, you build a detailed longitudinal health record that reveals trends, progress, and new opportunities.

FAQ
Common questions about the process
Everything you need to know about getting started with Rewind.
How long does onboarding take?
Most members complete onboarding in under ten minutes. The health questionnaire is the longest part and typically takes five to seven minutes. Connecting wearables is usually instant.
Do I need blood work to get started?
No. You can start with your health questionnaire and wearable data alone. However, blood work significantly improves the accuracy of your Biological Age calculation and personalised recommendations.
How often is my plan updated?
Your plan is continuously refined as new data comes in. Major plan updates typically occur after new blood work results, quarterly reviews, or significant changes in your wearable data trends.
Who reviews my health plan?
Every plan is reviewed by a longevity-focused clinician in our network. They validate the AI-generated recommendations, make clinical adjustments where necessary, and ensure your plan is safe and appropriate.
