It's been over a year since Jawbone's last flagship fitness tracker, and now the wearables company has halted production on its UP range, selling the remaining stock to a third-party reseller.
According to Tech Insider sources, it's "unclear" if Jawbone will start making the UP trackers again.
The UP2, UP3, and UP4 have allegedly lagged in sales (despite having frankly glorious app support), and has struggled to make a dent in wearables market against major competitors Fitbit and Apple in the five years since it entered the market.
Although $165 million in funding was raised in February, Jawbone has been forced to sell off the UP trackers at a discount to keep the rest of the business afloat, sources say. The funds raised this year are to be put into clinical-grade fitness trackers instead.
The UP tracker reportedly isn't the first Jawbone product to get the axe -- just last week Fortune revealed that Jawbone is also selling off its Bluetooth speakers, and discontinuing production on the range.
We have contacted Jawbone for comment, and will update the story as we learn more.
