But its emerged that one particular wearable fitness tracker is allegedly not working properly on people with dark colored skin.
Some black users have complained on forums that the band worn around their wrist cannot decipher their heart rate.
"I've no heart"… That's what my xiaomi mi band2 "said". (note: malfunction heart rate monitor) #jussaying #heartratemonitor #xiaomiband2

As reported by Blavity.com some black users have been experiencing problems with the device since October 2016, with many still waiting for the improvements to kick in.
According to a forum on the company's website, the issue still hasn't been fixed for many people as late as December 2016 and into January 2017.
"I am also facing the same problem," one user on the forum reports.
"The band is not working on me cause of dark skin. Hope Xiaomi will fix this very soon." However some forum members say the issue has been caused by a software bug.
Xiaomi says it is working on the heart rate detection issue.
