Fitbit Flex VS Flex 2: Fitness Trackers Comparison

Fitbit Flex VS Fitbit Flex 2: Fitbit has no shortage of trackers on the market. Two years since the first instalment of the trackers were launched, the company unveiled Fitbit Charge 2 and Flex 2 two days ago. Primarily the Fitbit Flex tracks movement 24 hours a day, including sleep patterns. Fitbit Flex has almost all the same sync functions as the Fitbit One and Zip. With the announcement of the second instalment of Flex, a lot of our readers have asked us for a comparison between the successor and predecessor.

Fitbit Flex VS Flex 2: Design

The Fitbit Flex is made for the fashion conscious folks. It’s rubbery wristband, thinner than a watch. The tracker is a pretty simple looking band with a push-in clasp strap. The brain of the Flex is built in the where the face of the tracker would’ve been. Should the rubber start to wear off, you can get yourself a new one. There are five different coloured straps available in the market. Fitbit Flex is more-or-less water-resistant meaning you can probably go to shower wearing the Flex but not swimming. In place of a display, there are five little white lights that tell you how well you are doing in trying to reach your daily goal.

The Fitbit Flex 2, on the other hand, is slimmer than the first Flex because the tracking module is 30% smaller. It has a similar clasping style and looks and feels more comfortable on the wrist. Like the original Flex, Flex 2 supports simple features, and it’s waterproof for up to 50m. Although swim-proof, the Fitbit issue a cautionary: After swimming or getting the band wet, we recommend drying off the band because, as with any wearable device, it’s best for your skin if the band is clean and dry. The trackers use LED lights to notify about calls, text that you receive on your handset (for this, of course, your smartphone needs to be connected to the device). Users can personalise the light to your liking, so that you can differentiate between calls, texts, alarms, reminders to move, etc.

Fitbit Flex VS Flex 2: Tracking

Flex tracks your food consumed, weight gained and movement among other things. Fitbit offers a free website that can be used with the Fitbit tracker where users have the ability to log their food, activities, and weight, to track over time. The Fitbit Flex will also track your movements while you’re asleep. First, you’ll have to enable the mode, though.

The Flex 2 is capable of tracking steps, active minutes, calories burned, hourly activity and sleep. All these are tracked automatically thanks to the SmartTrack feature. One of the highlights of Flex 2 is that it can track swimming in pools and oceans. It monitors duration and laps. The device can be used in freshwater and saltwater. The inclusion of swim tracking a massive feature that could be a huge selling point for the tracker.

Fitbit Flex VS Flex 2: Battery

There isn’t much of a difference between the battery capacity of Fitbit Flex and Flex 2, which means Flex 2 doesn’t offer the same battery we’d got two years ago. That’s disappointing. Check out the battery specifications below:

Fitbit Flex

  • Battery life: up to 5 days
  • Battery type: Lithium-polymer
  • Charge time: One to two hours
  • Radio transceiver: Bluetooth 4.0

Fitbit Flex 2

  • Battery life: up to 5 days
  • Battery type: Lithium-polymer
  • Charge time: One to two hours
  • Radio transceiver: Bluetooth 4.0

Wrap Up:

The Flex 2 is definitely an upgrade from the predecessor. The only catch in the not-so-impressive battery. Waterproofing is easily the most exciting new feature (though not entirely new) of the Flex 2. The fact that it’s an upgrade, reasonably-priced, pretty convenient and the smallest fitness tracker of the Fitbit family should be convincing enough to get yourself a pre-order.
