Know your biological age. Then rewind it.

What Rewind Life does

Rewind Life combines a personalized health protocol, biomarker testing, wearable signals, and clinical support into one continuously adapting system. It estimates your biological age, builds a daily protocol to improve it, and refines that protocol as new data comes in — from your sleep, recovery, lab tests, and lifestyle.

Membership starts at $1 per day and includes your Rewind Score, biological age tracking, daily actions, and continuous optimization. Optional add-ons include lab testing, physician consults, prescriptions, peptide protocols, and GLP-1 therapies.

How it works

1. Start with a 2-minute assessment

We estimate your biological age instantly and begin building your protocol — no blood test required to begin.

2. Optionally order biomarker testing

When you're ready, order an at-home test kit through the app. We measure the key systems that drive aging — metabolism, hormones, inflammation, cardiovascular health, and more. We don't test everything; we test what actually matters.

3. View your results in the dashboard

Results — including ApoB, LDL, hs-CRP, HbA1c, and other core markers — appear in your dashboard with sparklines, trends, and a single hero biological age metric.

4. Your protocol adapts continuously

Between tests, your system uses daily signals from your wearables — sleep, stress, HRV, recovery — to refine your protocol in real time. Most members test 2–4 times per year.

Built by doctors. Engineered for longevity.

Rewind Life is built and overseen by a medical board of longevity physicians and researchers. Our clinicians focus on healthspan and optimization, working alongside your existing primary care provider rather than replacing them.

Frequently asked questions

What is a Rewind Score?

Your Rewind Score is a simple way to understand your overall health. It combines your biology, lifestyle, and daily signals into one clear number — showing how your body is actually performing and changing over time.

How do I get my biological age?

Start with a quick 2-minute assessment. We estimate your biological age instantly and begin building your protocol. You can improve accuracy over time by connecting wearables or adding testing when you're ready.

Do I need to do blood testing?

No. Your system starts immediately from your assessment. Testing is optional — but most members choose to add it to replace estimates with precise biological insights and improve their results over time.

What do you test?

When you choose to test, we focus on the key systems that drive how fast you age — including metabolism, hormones, inflammation, heart health, and more. We don't test everything. We test what actually matters.

How often should I test?

Most members test 2–4 times per year to track progress and refine their protocol. Between tests, your system continues to adapt using daily signals like sleep, stress, and recovery.

Do I need a wearable device?

No. You can start without one. Wearables simply make your system smarter over time by adding real-time signals from your body. You can connect anytime.

What do I get for $1 per day?

You get access to your full Rewind system. This includes your personalized protocol, daily actions, Rewind Score, biological age tracking, and continuous optimization based on your data. Testing, doctors, and advanced therapies are added when you need them.

Do you offer doctors, prescriptions, or treatments?

Yes — when needed. Your protocol can include clinical support from Rewind doctors, including prescriptions, peptides, and advanced therapies. Everything is integrated into your system — no separate appointments or fragmented care.

Can I cancel anytime?

Yes. You can cancel anytime, with no lock-in contracts. You'll keep access until the end of your billing period.

Does Rewind replace my doctor?

No. Rewind works alongside your existing healthcare. Our clinicians focus on longevity and optimization, but we always recommend maintaining your relationship with your primary care provider.

How fast do I get results?

Your system starts instantly after your assessment. If you choose to test, results are typically available within a few days and automatically update your protocol.
