End the health guesswork

Calibre is available for adults aged 18 to 65 living in England, with a particular focus on 25 to 55-year-olds who are broadly well and looking for a holistic, proactive and expert-led approach to their health.

Calibre works alongside traditional healthcare and is not suitable as a first point of contact for new or urgent health concerns. Calibre is not currently suitable if you: are under 18 or over 65; are not resident in England; are experiencing new, worsening or urgent symptoms not yet discussed with a doctor, including mental health symptoms; are currently pregnant; or have a health condition that is unstable or not well controlled.

If unsure, contact info@getcalibre.com before signing up.

If you don’t feel your Health Assessment has given you greater clarity about your health, let us know within seven days of your assessment call with your dedicated doctor and we’ll refund your most recent payment in full, no questions asked.

Email refunds@getcalibre.com within seven days of your assessment call.

First-time members who qualify for our Money Back Guarantee are covered by that guarantee instead.

You’ll create your Calibre account and set up WhatsApp as your direct channel to the Calibre team. The app then guides you through completing your health questionnaires, connecting your wearable, uploading past medical records, booking your lab test and choosing your five-day lifestyle-tracking window.

Because health is a trajectory, not a snapshot. As we learn more about you and measure what changes, your Health Assessment and plan become more precise over time.

Week 1: Build your baseline
Complete your health questionnaires, connect your wearable, upload past medical records and book your lab test.

Week 2: Diagnostics
Complete your personalised blood and urine test at a Randox clinic, alongside five days of lifestyle tracking covering energy, blood pressure, nutrition, activity and sleep.

Week 3 to 4: Understand your health
Once all your information is complete, your dedicated doctor and Calibre’s causal AI bring it together in your Health Assessment. You meet your dedicated doctor to understand what’s driving your energy and long-term health and agree your first personalised plan.

From there
We track what changes, learn from the results and continuously refine your plan.

Your membership starts with a personalised blood and urine lab test covering 50+ biomarkers, selected to build a meaningful baseline for your energy and long-term health.

Every six months, you and your dedicated doctor decide which diagnostic will add the most value. This may mean targeted blood-marker retesting or an advanced test such as DEXA, VO₂ max or CGM. Your full blood and urine lab test is repeated annually.

This cycle continues throughout your membership.

We personalise our 50+ biomarker baseline test by asking you a targeted set of questions about your past health, current context and goals. Your answers help us select the markers most relevant to understanding your energy and long-term health.

An annual health check gives you a snapshot. Calibre is built around your trajectory. We decide what to measure, interpret it in the context of your full story, act on what matters and track what changes over time, working towards more energy today and lower long-term health risks.

A wearable can tell you something’s off, but it can’t tell you why. Calibre combines wearable data with diagnostics, lifestyle and your health history to understand what it means for you and what to do about it.

Calibre was co-founded by physician and sports scientist Dr Reinhold Innerhofer. Every member has a dedicated doctor, supported by Calibre’s clinical methodology and causal AI. Clinical care and interpretation are delivered directly by Calibre as a CQC-regulated care provider.

No. Calibre is your primary relationship for proactive health, working alongside traditional healthcare. We help you understand what’s driving your health and how to improve it over time. When something requires specialist or urgent care, your dedicated doctor guides you to the right service.

Yes. Calibre meets UK GDPR and healthcare data-protection standards as a CQC-regulated care provider. Your health information is only accessible to you and the people involved in your care. We don’t share it with third parties without your consent, other than in exceptional circumstances where we have a legal obligation to do so.
