--Track more accurate steps when cycling--

It¡¯s kind of strange that we wear fitbit on our wrists to tell us how many steps we¡¯ve walked. In fact, most of the activities we track from up high tend to originate from below the waist. In some activities that most wrist-based trackers can¡¯t measure, such as cycling, you will have problems with it recording your steps because your hands aren't always swinging....In this case, you need something to move your fitbit from wrist to ankle, and let it track and measure your leg movement, that is the best solution!

Our extender band expand the fitbit wristband overall length that allow you wear fitbit around your ankle to get more accurate steps. The band fit snugly to fitbit wristband, very secure, you will never have any issue or worry of it falling off. We highly recommend you to use our extender band when cycling, running on a treadmill, or pushing a grocery cart, etc.

--Allow Fitbit Alta HR reading your heart rate--

Yes, you can count on it. You may know, most ankle band does not work for fitbit alta hr to track heart rate, because the tracker goes into a pocket on the band and doesn't make physical contact with the skin. In contrast, our extender just connects with fitbit wristband, there is no shielding between fitbit tracker and the skin, consequently, our extender allows the fitbit to read heart rate correctly. (Notice: our package did not include fitbit tracker or wristband)
