Best wearables in the UK
Fitness bands and smartwatches for training and daily wear. Two research-led picks, compared on the things that matter after the first week.
Wearables sit on your wrist all day, so comfort, battery life and the quality of the data matter more than a long feature list. The two devices here represent the two main paths: a slim fitness band with built-in GPS and a focus on training and sleep, and a full smartwatch with a large screen, apps and deep iPhone integration. We compare battery claims, health sensors, GPS, water resistance and the subscription question. Neither is a medical device, and neither replaces a doctor; the useful comparison is about which one you will actually keep wearing.
