(Pocket-lint) - OnePlus is about to launch its first fitness tracker, likely dubbed the OnePlus Band and - if information from a well-known leaker is accurate - it could launch as soon as next week. 

11 January is the date to pencil in your diaries according to Ishan Agarwal, who tweeted the release date along with some previously unknown specs. 

As with any modern day fitness tracker you get heart-rate monitoring throughout the day, sleep tracking at night and long battery life (14 days to be precise). 

In addition to that, Agarwal claims we'll also see SpO2 blood oxygen saturation tracking and 13 different activity modes for tracking specific workouts/activities. 

It's said to feature a 1.1-inch AMOLED touchscreen on the front and - looking at teasers from OnePlus itself - it's the usual rectangular vertical panel sitting within a slim band. 

Of course, a fitness band is no use if it can't survive in wet weather or can't cope with your sweatiest workouts and so it's no surprise that IP68 water and dust resistance is also expected. 

The only other thing worth noting right now is that it seems the band is being geared towards the Indian market. 

Agarwal mentions the Indian launch date in his tweet, while OnePlus' Indian Twitter handle has been the most active in promoting its imminent launch.
