The Flex 2 is a small activity tracker which can be worn as a slim wristband (normally), or as a bangle or pendant.
In features offered, it lies somewhere between the Zip and the Alta.

It is quite elegant looking but only has LED lights, not a readable display.

SmartTrack automatically records workouts – runs, rides, elliptical, sports and aerobic workouts – and syncs wirelessly to your Fitbit app.

It tracks steps, distance, calories and active minutes. It does not track stairs but does monitor sleep.

It can track how well you sleep and for how long and you can set a silent alarm to wake you with a small vibration.

The Flex 2 is swim-proof – an upgrade on the original Flex which, though supposedly waterproof, was not recommended to be worn in the shower or pool.

To help you stay active throughout the day, Flex 2 sends Reminders to Move that encourage you to take 250 steps every hour.

The Flex 2 has call and text notifications – it vibrates and flashes lights which are colour-coded.

Battery life is good with up to 5 days use before charging. You charge it by plugging it into a USB port or approved USB mains charger.

Fitbit HR Alta Fitness Wrist Band

The question you’re bound to be asking is “What’s the difference between the Alta and the Alta HR?”

Well HR stands for Heart Rate and that is the difference – the HR has a heart, or rather Pulse rate monitor added. It constantly monitors your heart rate throughout the day so you can see what your resting heart rate is and how high it it goes during workouts. These figures can give you a good indication of the health of your heart. With the app you can use heart rate zones to increase or decrease your effort.

Monitoring the heart rate can also give you an indication of how many calories your using.

The HR also has a more secure wrist strap clasp.

Fitbit Blaze Smart Fitness Watch

Where the other Fitbits are activity trackers which may or may not be worn on the wrist and may or may not display the time, the Blaze is positioned as a stylish Smart Watch whose main functionality is that of fitness and activity tracker. In other words, it looks more like a watch and while many people who like their own wristwatch might wear a Fitbit wristband on their other wrist, some might be happy to replace their existing watch with the Blaze.


The look of actual watch face is versatile, having a hi-res colour touchscreen with a variety of faces to choose from.

Of the standard flexible elastomer material Fitbit straps, there are 3 strap colo(u)rs to choose from: Black, Blue, and Plum. However, there is also a range of optional leather or metal straps sold separately but, while adding a stylish look, these are not as waterproof as the standard strap.

The Blaze fits into a frame to which the strap is attached so it is pretty quick and easy to change. Unfortunately, you also have to remove the Blaze from its frame to charge it by inserting into a charging dock but I daresay that’s something you’ll just get used to.

Fitbit claim a 5-day charging cycle but it depends on various settings. A 3-4 day recharging cycle might be more realistic.


As an activity tracker, the Fitbit Blaze has a similar features to the Surge, including all-day PurePulse™ heart-rate monitoring, multi-sport tracking, sleep monitoring and the ability to control your music. Furthermore, the Blaze adds Calendar alerts to call and text alerts.

One minus point compared to the Surge is that, while it has GPS functionality, is does not have GPS built into the watch, but uses your phone, so you have to have your phone with you for it to work.

There are buttons on the side of the Blaze but the screen is touch-sensitive and you swipe across or down to see different screens and settings.

The Blaze links up with third party company FitStart for workout coaching – you can start a FitStar workout and get on screen workout instructions on your watch.

Of course, like all Fitbits, it links up with mobile apps and computers for detailed analysis of your progress.
