The wearables market has really taken off over the past couple of years bringing with it a plethora of devices from smartwatches and heart rate measuring headphones to sports watches and activity trackers.

There is such a breadth of choice out there, it's difficult to know where to start, let alone make the right decision on the one best for you. This feature rounds up the best activity trackers available to buy today and we will be updating it as we test out the latest devices.

For now, we have only included the products we have tested fully and it focuses around the wearables that are always-on and always tracking your activity, rather than those that specialise in specific activities.

For those that are after something that will count your steps and calories, monitor your sleep and perhaps even have the added bonus of reading your heart rate, you have come to the right place. Here are the best fitness wearables to consider if you want to get up, start moving and stay ahead of the game.

Pocket-lintMicrosoft Band

If taken on its features alone, the Microsoft Band 2 would be the smart band to beat, because it offers more than most of the competition out there.

The problem, however, is that the Band 2's design still isn't good enough like its predecessor. An activity tracker or smartwatch is a device you want to wear all day, but the Band 2 is just grating. Having to wear it at night after enduring a day is just a step too far.

Like the original device, the Band 2 has heaps of potential and that's why it sits in the position it is in here. Tweak the design to factor in comfort, trim the physical scale, and Microsoft could have a winning device that would be much further up. For now, however, it's an echo of the original: the Band 2 isn't quite there yet, hindered once again by form, not by function.

PRICE: £200,

Pocket-lintMisfit Ray

The Misfit Ray is a good-looking and affordable activity tracker. Its subtle design means it can be worn alongside a traditional watch without looking like you're doubling-down to placate your time-telling OCD. No need to constantly recharge it is a big plus point too.

Its activity tracking is basic though and not hugely accurate from our experience, while the app platform is not nearly as comprehensive as some competitors. That tube design isn't the most comfortable to wear either.

Misfit does have price on its side however and the incoming customised accessories might add more appeal too. Where the Microsoft Band 2 is delivery over design, the Misfit Ray is the opposite.

PRICE: £49.99,

Pocket-lintWithings Go

The Withings Go is one of the cheapest activity trackers out there, sitting in line with the likes of the Misfit Flash in terms of price. Although the Go's E Ink display couldn't be called pretty, it is functional for showing step progress and, therefore, a good choice.

The biggest problem the Go faces is that there isn't a huge price difference between the budget and higher-end of the activity tracking market. So an extra £50 could get you a better looking tracker with a colour OLED display, even better app experience and smart notifications, such as the Fitbit Alta that sits a little higher up this list.

For those who want what's essentially a glorified pedometer with a few extra features, the Go is a great choice. For those after a proper activity tracker, there are better options if keep clicking, providing you can afford to spend a little extra.

PRICE: £49.99,

Pocket-lintWithings Activite Pop

The Withings Activité Pop is a cheaper, more colourful version of the Withings Activité watch, which was unveiled at IFA 2014. The Activité Pop knocks £200 off the price tag of the original Swiss Made device and introduces the same functions but with a lower quality materials.

It's a good looking device, just like the Activité, and it's comfortable and lightweight too. Rather than offering a polished stainless steel casing, sapphire glass and a french calf leather strap however, the Activité Pop opts for a silicone strap, no sapphire glass and a colourful PVD-coated shell.

The Activité Pop will count your steps, calories burned, distance and monitor your sleep like many other activity trackers but its design makes its competitors look bulky, clunky, and, well, ugly by comparison. The only better-looking devices are the original Withings Activité and Activité Steel.

PRICE: £79.99,

Pocket-lintWithings Activite Steel

The Withings Activité Steel is the third Activité tracker from the french company and the fourth fitness tracker overall. It's another beautiful and well-made device and it comes with a saving of £180 compared to the original Activité, even if that means a few compromises.

Like the other Activité devices, the Steel is all about managing expectations. If you want a step tracker that you can wear everyday as a replacement for a watch then it's the ideal companion. If you're looking for a smartwatch or sportswatch that will reward you at the gym, give you accurate calories or even decent running data then this is not the answer, nor does it claim to be.

The Withings Activité Steel is a great device for getting you up, moving and looking good while you do it. As long as you are aware of its features and limitations, it's a perfect half-way balance between the original Activité and the Pop.

PRICE: £140,

Pocket-lintFitbit Blaze

The Fitbit Blaze brings all the features of the older Fitbit Charge HR, but adds text notifications, music control, a coloured touchscreen and connected GPS, along with a couple of other additions.

Don't mistake it for a smartwatch - it isn't. The Blaze is more of a smart fitness watch that adds a couple of smart features, such as the ability to accept or reject incoming calls, but it has no third party app support. Ultimately, it is fitness tracker that looks more like a watch than Fitbit's other devices.

The Blaze's display is beautiful and the Fitbit platform is fantastic, but it's not the tracker for everyone. It has some great features, including the Multi-Sport tracking, automatic activity recognition and the FitStar workouts. The price is much higher than the newer Charge 2 though - and you don't get a whole lot extra functionality for your money.

PRICE: £129.99,

Pocket-lintWithings Activite

The Withings Activité was announced in September 2014 and it is the Swiss Made, and consequently more expensive, version of the Withings Activité Pop that we mentioned above. It features a beautiful design with a fantastic build quality and it is the first activity tracker to truly look good on.

The Activité appears to be an average analogue watch on first glance, but it doesn't just tell you the time, it also tracks your activity, counts your burned calories and monitors your sleep patterns. There is an 8-month battery life and it is iOS and Android compatible, with a decent app running the show that is great when it comes to linking up with other platforms such as MyFitnessPal.

The Withings Activité has its flaws like others on this list, the most irritating of which is not counting steps properly if you aren't moving your arm. Overall though, the Activité is a beautifully designed device that delivers on its promise of being a wearable you actually want to wear so for those after a stylish activity tracker, this is the one to beat.

PRICE: £269,

Pocket-lintJawbone UP3

The Jawbone UP3 is one of the latest activity trackers in the UP portfolio and it brings a lovely design, good battery life, a brilliant app platform and a range of extra features to the party. It is the perfect tracker for the Average Joe, the person who wants a device they can wear all day and all night. The UP3 delivers superior sleep tracking over its competitors, as well as accurate step tracking, although it's worth mentioning it is not quite as accurate as the Fitbit Charge 2.

In a nutshell, the UP3 is all about making you realise how much you aren't moving and encouraging you to move more, and it does this fantastically through its Smart Coach and Duel features. What it isn't quite as good at is exercise tracking. There is no way to tell the UP3 you are about to do an activity before you've actually done it, you just have to assume it will automatically detect so you can tell it what you did after and it doesn't always pick it up.

For that reason, the Jawbone UP3 probably won't be quite right for the gym geek, especially if you want more detailed workout analysis such as active heart rate tracking. For everyone else though, the UP3 is a fantastic choice. As long as you understand what Jawbone is trying to achieve, the UP3 won't let you down.

PRICE: £189.99,

Pocket-lintFitbit Flex 2 - 1

The Fitbit Flex 2 is a simple yet effective tracker with a more exciting design than its predecessor. Not a great deal has changed in terms of looks, but Fitbit has done enough to ensure the new-generation model doesn't look like a boring rubber band. The far better two-pin clasp ensures a solid, comfortable fit too.

The addition of basic smartphone notifications and waterproofing is also welcome, and we love that Fitbit has continued to embrace the fashion angle with more interchangeable accessories to smarten up the Flex 2's potential too.

The Fitbit Flex 2 has a good thing going on: it's simple, stylish and unobtrusive. It won't be for those who want more data such as heart-rate or GPS tracking, but it's a great device for those after basic tracking.

PRICE: from £60,

Pocket-lintFitbit Alta

The Fitbit Alta is by far the most stylish of the Fitbit bunch, especially when paired with the additional straps, even if it isn't as feature rich as some of its siblings.

The Alta misses out a few key functions, such as heart rate monitoring, elevation data, GPS and waterproofing but for basic activity tracking, it's a fabulous device.

Accuracy of step tracking is good, smart notifications are useful, the OLED display is lovely and the Fitbit app is one of the best out there. For some the Alta will be a little too basic, but for others, it will be a winner, especially in terms of its looks.

PRICE: £79,

Pocket-lintGarmin Vivosmart HR+

The Garmin Vivosmart HR+ is something of a surprise package, stuffing a lot of functionality into a device that's only a little larger than some other fitness tracker bands on this list.

It's a little more expensive than most at £169.99, and it isn't as good looking as Fitbit's latest devices, but it's the feature set that appeals, with both heart rate monitoring and GPS on board.

The Garmin Vivosmart HR+ is an ideal device for someone who wants to track daily activity as well as record runs or walks in more detail, but doesn't want to go the whole hog and start wearing a running watch all the time.

PRICE: £200,

Pocket-lintFitbit Charge 2

The Fitbit Charge 2 replaces the company's Charge HR, which although is no longer available to buy through Fitbit, was a fantastic tracker. The new device takes the best features from the Charge HR, such as continuous heart rate monitoring, and adds a few more including VO2 Max, Guided Breathing and Connected GPS.

It also takes on Fitbit's new design ethos, found on the recently launched Alta, with interchangeable straps, a solid build quality and a larger, informative OLED display. There are things that could be improved, such as smartphone notifications supporting third-party apps, waterproofing would be very much welcomed, and some data could be more easily accessible, but overall, the Charge 2 is great. 

If you're looking for a well-designed, accurate fitness tracker with a fantastic app platform, then the Charge 2 fully takes charge.

PRICE: £149.99,
