Today's best Fitbit Sense deal
Fitbit Sense: £299.99 £105 at Amazon
Save £104.99 - The Sense is a top-end Fitbit that rarely drops below £220, so this is a real bargain. We're expecting the price to jump back up again soon, so don't hang around if you're interested.
However, the Sense also has a couple of special sensors that you won't find on most fitness trackers. The first of these measures stress by monitoring EDA (electrodermal activity) responses. Put simply, adrenal activity causes you to sweat, which makes your skin more conductive. The watch uses a very mild electrical current to monitor changes in conductivity over time.
The Sense also has an ECG sensor, which can monitor for signs of atrial fibrillation (an irregular heart rate), which should be investigated by a doctor.
It monitors sleep too, lets you make contactless purchases via Fitbit Pay, and displays smartphone notifications right on your wrist. It's nicely designed too, with a rounded design and soft silicone band that make it comfortable to wear day and night.
