This article originally appeared on ABACUS In another sign that wrist-worn wearables are going strong this year, China’s Huami says it’s selling more fitness trackers than in 2018. The Hefei-based manufacturer is the sole supplier of Xiaomi wearables and maker of its own Amazfit fitness trackers. Between July and September, it shipped nearly 70% more units than the same period last year. And in just the first nine months of this year, it already shipped as many units as it did for all of 2018. “Our revenue performance was primarily the result of the strong sales of both [Xiaomi’s] Mi Band 4 and our newly released Amazfit products,” said Huami CEO Wang Huang. Xiaomi is currently the world’s best-selling wrist wearable brand, according to IDC’s most recent figures . It outranks Apple, Huawei, Fitbit and Samsung. Analysts say China remains Xiaomi’s biggest market, although the company is aggressively expanding overseas. It recently announced it would start selling phones and wearables in Japan next year.
