The Last Word

Fitbit has a wide range of fitness trackers for all types from the Fitness Buff to those looking to improve general fitness levels and this is where the Flex 2 comes in. Fitbit's latest basic fitness tracker is small, slender and extremely light-weight and it is also very versatile. The Fitness core can be transferred from a rubber wristband you may wear swimming or to the gym, into a bangle or pendant so you can keep tracking your fitness while out on the town, or heading to the office. The Flex 2 is very much a basic fitness tracker for step count, calorie count and general exercises however it does not have a Heart Rate Monitor, GPS or altimeter therefore if you are looking for more in depth information or coaching you need to look at another fitness tracker. That said if general fitness is your quest and you want a versatile tracker the Flex 2 could be what you're looking for.

The Review

A look at Fitbit’s new Flex 2, what can you expect from th latest design?

read the full review ...

Design

The Fitbit Flex 2 is a basic fitness tracker and as such you can’t expect and won’t get a flashy colour display or a lot of features a premium level fitness tracker has. Therefore the Flex 2 has the luxury of keeping things simple and benefiting from an ultra slim and lightweight tracking core. Fitbit has used this to it’s advantage and given the Flex 2 a customisable design, you can place the removable tracking core in bands, bangles and pendants. This approach means the Flex 2 can look sporty in a soft, flexible rubber wristband, or stylish in a metal bangle or pendant meaning you can keep tracking your steps whether you’re in the gym or out and about on the town. The rubber wristband has a button clasp similar to the previous Fitbit Flex, however the old model was quite stiff and difficult to close at times, the new Flex 2 button clasp is easier to close, though it still requires a firm press. Fitbit have made the small tracking core water resistant up to 50 m, therefore you can wear it in the shower or even swimming, however if you want to take the Flex 2 swimming you should ensure it is in the rubber wristband and dry it off after every use. The Flex 2’s customisable design is not unique but Fitbit’s approach is stylish, sporty, light and comfortable to wear, it’s versatility will appeal to many.

Memory

The Flex 2 saves 7 days of detailed motion data, minute by minute so you do not need to be connected to your device at all times. If you are away or just simply don’t want to carry your mobile device you can track your steps and sync up later. The Flex 2 will also save daily totals for past 30 days.

Display

While the Flex 2 does not have a display (of any kind) there are 5 LED indicator lights which will light up to tell you when steps are being counted or a particular exercise, like swimming, is being tracked. It will also indicate when you get smart notifications, however as you can imagine it is a little confusing, with no information displayed at all it can be difficult to tell exactly what those little lights are saying. In the app you will find information on what the lights mean, it’s worth a look to have an idea of what the Flex 2 is trying to tell you.

Ease of Use

 

Usability: The Fitbit Flex 2 is compatible with iOS, Android and Windows, just download the Fitbit App and pair the Flex 2 to your mobile device so you can sync up your data to view your progress. The Fitbit App is well established with plenty of features and easy to use, it may not be as detailed as the Garmin App however for those using the Flex 2 or looking for general fitness tracking it is more than adequate. The Flex 2 also supports smart notifications, however like many basic fitness trackers you cannot answer calls or texts. You can also set a silent alarm  with your Flex 2, instead of waking up to your mobile alarm ringing you can set the Flex 2 to vibrate when it’s time to get up, some may find it annoying but you actually get used to it after a few mornings. 

Fitness: The Flex 2 is a basic fitness tracker, there is no point picking up the Flex 2 if you want very detailed information or coaching, if this is what you want you need to look at a premium level device. However, if you are looking to track general fitness and get more mobile the Flex 2 covers all the basics like step count, calorie count and it even vibrates to remind you to move. If you have been sitting idle for too long or have a long way to go to meet your step goal the Flex 2 will vibrate to remind you to get off your couch. The Flex 2 uses Smart Track which means it will begin to track your steps automatically and will also track your activities like jogging, cycling etc. automatically, you can always tap the Flex 2 to being tracking also if you wish. Unfortunately the Flex 2 will not automatically track swimming as Fitbit says this will rain the battery too much. The Flex 2 will also reward you by celebrating when you reach your goals, it may seem small but the gratification you feel when the Flex 2 buzzes to let you know you have reached your step goal is actually a great motivational tool, simple but effective and you will find yourself waiting on that little reward. Fitbit has also equipped the Flex 2 to track your sleep, though this is quite basic as you can imagine. Unfortunately the Flex 2 does not have a Heart Rate Monitor or GPS for location or altimeter to give you added ‘points’ for climbing stairs, while this is disappointing its not surprising for a basic fitness tracker, just a point to note.

Connectivity

The Flex 2 connects to your mobile device via Bluetooth 4.0, whether you use iOS, Android or Windows and has a syncing range of up to 6.1 m, meaning you can keep your device in your bag while at the gym as long as it’s within this distance and it will continue to sync data.

Battery Life

Fitbit has packed the Flex 2 with a lithium-polymer battery which is boasts will last you up to 5 days before needing a charge. While some may find this underwhelming for a basic fitness tracker, given the small, slender, lightweight and versatile design it’s actually quite impressive, I would happily stick with a week long battery life for such a small versatile device. The charge time is however 1-2 hours with no quick charge, so you need to pay attention to the e-mail Fitbit will send you to let you know when the battery is running low so you do not get caught short when you want to go for a run.

Portability

Not only is the Flex 2 small and thin but it also weighs a mere 0.83 oz, even with the wristband or bangle the Flex 2 is extremely lightweight and therefore comfortable to wear all day and night, though at night the rubber wristband is more comfortable, you will actually forget you have it on you. Part of the Flex 2’s charm is it’s versatility, if you are heading on a night out or just want a little more style and sport you can change the Flex 2 core into a bangle or pendant, meaning you should always have it with you and continue head towards your daily goals.
