The Fitbit Flex 2 pedometer is the epitome of step tracking – it’s sleek and simple, but the accompanying app packs enough features to show a complete timeline of your fitness and steps. It’s also so small it won’t get in your way while you work out, type, do chores or take a nap. For these reasons and more, we give the Fitbit Flex 2 our Top Ten Reviews Bronze Award.

Tracking Accuracy

During testing, we found the Flex 2 was only about 25 steps off for every 2,500 we took, which puts it up in the 99 percent range for accuracy. This is one of the best pedometers for walking since it also tracks distance closely. For every mile we walked, it was only off by about 0.1 miles – this is only one-tenth of a mile, or less than 500 feet.



The Flex 2 is exceedingly easy to use – you just tap it. When you double tap with your finger, it lights up the five LED lights to indicate how close you are to reaching your step goal. For example, if you’ve walked 8,000 steps of your 10,000-step goal, four of the five lights will light up. You’re even rewarded for reaching your goal with a light show and vibrations. One of the device’s biggest downsides is it doesn’t have a screen, which would give you a quick-view of your actual step count. For this, you need to pull open the app.

This wristband step counter has a five-day battery life and is rechargeable. The tracker itself pops out of the plastic band and slides into the USB charger. During testing, we found that the pedometer doesn’t take very long to charge – just about the time it takes to shower and get ready in the morning.

The standard Flex 2 comes with a rubber plastic wristband, and you can choose from four different colors. You can also buy upgraded bands, such as bangles and pendants, made from other materials like metal.

One of the Flex 2’s best features is that it’s fully waterproof. Fitbit rates it up to 5 ATM, which is deep enough should you want to get in some laps at the pool, take it on an island getaway or wear it on a rainy run.

You can even wear the Flex 2 to bed, so it’s a good thing it’s so comfortable. It knows when you fall asleep, toss and turn, and get up in the middle of the night, and you can read reports in the app about how well you sleep every night. You can even wake up with the device’s silent alarm, which gently vibrates to let you know it’s time to get up.

Apps & Connectivity

The Fitbit app is far superior to any other in our review. It has everything you need to stay on top of your fitness goals. It’s simple to use on iOS and Android devices and is accessible from your desktop too. You can use it to control custom goals and choose which ones display as well as set which smartphone notifications you receive, alarms, reminders to move and more. For the most accurate tracking results, you should enter information about your height, weight, age, gender, stride length and more in the app.

Like the best step counters, the Fitbit Flex 2 is Bluetooth-enabled, so you can seamlessly sync your data. Depending on how long you want the battery to last, you can set the pedometer to transfer data every minute or only manually when you open the app. You have access to charts, data and historical stats for every step you’ve ever taken – but only if you upload data every 30 days; after that, it may be lost.

Help & Support

Fitbit provides a 12-month warranty for the Flex 2. The warranty starts when you activate your pedometer, and we found that Fitbit even honors the warranty if the model you buy is discontinued. This step counter is also covered by Fitbit’s excellent customer service. On the Fitbit website, you’ll find get-started guides, forums, contact information and a chat feature.


The Fitbit Flex 2 is one of the best pedometers because it’s accurate, easy to use, and backed by a powerful and useful app. Whether you’re a hardcore trainer or a casual walker, the Flex 2 conforms to your routine and provides you with information to help you stay healthy.
