Fitbit Flex 2 Review

The new Fitibit Flex 2 is fullt waterproof so you can now take it in the shower and pool. Is it really worth getting the Flex 2? We tested the device and posted our review below.

  • Sleek design
  • Comfortable to wear
  • Waterproof
  • Automatically detects and tracks exercises
  • Does not track floors
  • Basic fitness tracking
  • Software has bugs and compatibility issues
  • Limited sleep data

The Device

The device itself comes in two sizes, one for larger wrists and the other for smaller wrists. It is lightweight and comfortable to wear. Most of the time when I was wearing it, I did not realize I had it on. You can tap the device twice to display the progress towards your call. I set the device to the default goal of 10,000 steps. It lights up one to five of the lights, depending on how far you are along towards your goal.

The setup is very quick and easy to complete in a few minutes. The device communicated with Bluetooth so you just need to make sure your Bluetooth is turned on. In our package it seemed like the larger one was missing a piece. We had to use the smaller one for this reason. We also reported this to Fitbit and were told to contact the retailer which was Sports Chek. We were unable to get this fixed as Sports Chek to do not provide returns on faulty items that are not in original packaging. Although it was 2 weeks old, Sports Chek believe it acceptable to sell faulty products and not honor a return based on packaging.

Fitbit Setup


Fitbit claim that the device can receive notifications for calls and texts. The Android devices we tested this with did not work however.

When your mobile device receives a call or text message, your Fitbit Flex 2 vibrates and shows a light pattern to remind you to check your phone.

Sleep Data

The Fitbit Flex 2 provides limited sleep data. Unlike other Fitbit models it does not provide insights into REM sleep. It does however track when you fall asleep, when you wake up and how many times you were restless in the night.

Swimming Data

The first time I used the Fitbit Flex in the pool I was very excited to see the results as this was the main reason for me to choose this device. It can go in the water! When I dried off and checked the app, I saw that no swimming data was logged. When I further investigated this, it was because the ‘auto detect swim activity’ was turned off. I turned it on, set my pool to 25 M and it would then automatically detect swimming without issue.


I was told by someone that it detects strokes. I found it pretty much told me how many meters I swam.

Sync Issue

After a week or two I noticed that the Fitbit stopped tracking my sleep. Shortly after that I noticed that the device was not tracking steps. This was happening on both Windows 10 and Android app.

The app stopped tracking steps as pictured below.

Other Issues

After testing the device for 2 weeks I found there were too many issues to continue to use the Fitbit Flex 2. It seems like Fitbit are falsely misleading customers into what devices they support. Windows 10 and Android are clearly mentioned as supported. It turns out they are not and sync issues are just one of many issues that seem to be reported with this device.

Windows 10 Issues

Users on Windows 10 also have been reporting issues with syncing. When we contacted support they said they do not support Windows 10.

When we contacted support, we were directed to troubleshooting steps that involve removing the device, restarting the device. We were eventually told that the Windows and Android devices we were using are not compatible with Fitbit.

Warranty and Returns

We purchased our product through Sports Chek and they were not willing to honor a return for device although it was not working and was purchased with missing pieces. We reached out to Sports Chek for comment on this and they simply redirected to their returns policy page that stats: all software and electronic media products must be returned unopened to be eligible for a return.

Should I but a Fitbit Flex 2

Android and Windows 10 are 2 of the most common platforms for desktop and mobile users. If you are unable to support these products, then you may as well close your doors. Being shut down from support at Fitbit was a big eyeopener, especially since they make such a big deal about Android and Windows 10 apps. Instead of the Fitbit Flex 2, I have been hearing much better things about the MOOV NOW fitness tracker.

    I guess you shouldn’t have purchased from a place like Sports Check

      Yes I now know not to purchase anything there. It was funny they made a big deal about the return policy when I purchased it. When I realized it was missing a piece and faulty I asked if I could return and they simply highlighted the small print on their website. Sigh.

    Check out the MOOV NOW it is also a swimming tracker but works much better than Fitbit.
