Very useful. I use all the features and its excellent and accurate

This product has helped me stay motivated to exercise. Setting goals and having the watch celebrate when you reach it is so encouraging. Im still have a problem with my water not resetting at midnight.

The Fitbit Sense is the flagship device in the Fitbit range, the top device from one of the top names in wearables – and we've had one strapped to our wrist for the past couple of weeks to try and figure out whether or not it's worth the US$299.95 that you'll have to pay to get hold of one.

The Fitbit Sense is about more than just getting in shape—it’s about getting healthy. I get a lot of pitches for gadgets claiming to offer better sleep, health, and fitness, and many of them feel like high-tech snake oil. For every ailment, there seems to be a tech-based solution.

Attractive, Long battery life, Comprehensive fitness/health features

Small app store, No Spotify music storage

This tracker measures stress. Sort of.

Very good battery life (up to a week). Beautiful screen. Easy-to-navigate app and easily customizable. Works with Google Assistant as well as Alexa. Fitbit Premium still rules. It can measure blood oxygen (SpO2) levels and electrodermal activity for stress. Sensors are accurate.

New SpO2 and stress-management tools are less helpful than they sound. Optical O2 sensors bug out occasionally. Too many weird operational hiccups for a premium-priced tracker.

Not every Fitbit offers all of the features listed below. Some functions are more premium, reserved for higher-end models like the Sense, while others are fairly standard across nearly every device the brand offers.

The Fitbit Sense adds a whole slew of sensors to the Fitbit lineup to track everything from stress to blood oxygen levels, temperature, sleep and even has an FDA-cleared electrocardiogram (ECG or EKG). On top of all that, the $329 (£299, AU$499) Sense also doubles as a regular smartwatch and fitness tracker. And while the Sense still has fitness at its core, it wants to be your daily wellness coach now, too.

The Sense tracks your stress, temperature, blood oxygen and sleep. But interpreting all this data can be puzzling.

Always-on screen is bright and easy to see; Detailed sleep analysis; ECG is easy to use; Built-in GPS; Google Assistant is versatile;

Stress tracking doesn't tell you much yet; No onboard music storage; Not as responsive or fast as other smartwatches;

If you are looking for a wearable with specialized fitness features, then this is a good option

Comfortable to wear ; Nice OLED display; EDA, ECG, SpO2 and a skin temperature sensor make the Sense unrivalled for health features; Apple Watch-embarrassing battery life ;

Seriously buggy and slow; Data overload can be both vague and confusing; Forces you into selecting a certain watchface for SpO2 measurements ; You need Fitbit Premium to maximise it;
