One great deal we’ve found today is on the immensely useful Fitbit Charge 6 fitness tracker. This handy device can be a huge boon for your health, and while it’d normally set you back $160, this Prime Day deal knocks it down by 38% to just $100.

Xiaomi's Smart Band 10 combines sleek design and standout battery life, continuing its reign as the best value in budget wearables.

From telling you how fast you are “ageing”, to giving you a sleep score and even keeping tabs on your blood pressure — fitness trackers and smart watches are more focused on health than ever.

You get just about every possible health metric from the Whoop MG, but it's auto-detection lets it down. How does it fare overall?
