Just Because a Device Measures Something Doesn't Mean That Measurement Matters

The global wearables market is worth over £50 billion. Everyone's wearing something - a smartwatch, a ring, a patch. The question is: does it improve your health?

Some health tech has strong clinical evidence. Home blood pressure monitors improve cardiovascular outcomes. Pulse oximeters save lives in people with respiratory conditions.

But for every validated medical device, there are a dozen gadgets promising to 'optimise your health' based on metrics that don't predict anything meaningful.

We've applied the same evidence-based approach we use for supplements and medications. Every device on this page has been reviewed against clinical research.
