The Fitbit Flex 2 is an affordable activity tracker at the entry-level end of Fitbit’s product lineup. It is an upgrade from the original Fitbit Flex and was released along with the new Charge 2.

This fitness band does the basics of activity and step tracking but it also has a few new additions that make it more appealing. Here is a quick Fitbit Flex 2 review to help you learn more about this fitness tool and decide whether it is worth buying.

Features of the Fitbit Flex 2 Activity Tracker

When buying the Fitbit Flex 2, you can choose from a range of colors thanks to the removable elastomer bands that come with this unit. It is also possible attach other accessories on the tracker other than different colored bands.

For instance, a pendant accessory will let you wear the Fitbit Flex 2 around your neck whereas attaching the tracker to a polished bangle turns it into a fashion accessory.

Depending on how you wear your Fitbit Flex 2, it can monitor steps, calories, distance traveled, swimming stats and sleep quality. The tracker also sends buzzing alerts throughout the day that motivate you to keep moving. More features to expect from the Fitbit Flex 2 include:

  • Waterproof design: A new addition to the Fitbit Flex 2, the waterproof body on this unit makes it ideal for tracking swimming stats. Swim tracking is disabled by default, but once configured, you will be able to count laps and log activity data for up to four different swimming strokes.
  • Relays smart phone notifications: Although the Fitbit Flex does not relay calendar notifications, it will show both incoming calls and text messages from your Android or iOS smart phone. The tracker vibrates and lights up LEDs on the front panel to notify you when there is an incoming call or text message. Beyond basic SMS forwarding, the Fitbit Flex 2 also relays messages from WhatsApp and Facebook messenger.
  • SmartTrack technology: As with all Fitbit activity trackers, the Flex 2 automatically tracks activities such as running and walking without having to tap through various settings on the display.

Is the Fitbit Flex 2 Activity Tracker Worth Buying?

Compared to the original Flex model, the Fitbit Flex 2 is a decent upgrade with the addition of waterproofing.

This means that you don’t have to take it off when having a shower. The tracker’s ability to forward caller ID and notifications for incoming texts is also a good addition. There are certainly other more advanced fitness trackers out there, but if you are on a budget, the Fitbit Flex 2 offers reasonable value considering its price range.


  • Long battery life (lasts up to 5 days on a single charge)
  • Sleek and comfortable design
  • Waterproof under water

  • Monitors time spent restless or awake to let gauge sleep quality
  • Affordable price point

  • Lacks music control and custom clock faces

If you want to get a basic Fitbit activity tracker for less money, the Fitbit Flex 2 is the model to choose. It’s affordable, waterproof and will track basic fitness stats that let you know how active you are throughout the day.
