Re/code reports that Jawbone will this week announce support for other operating systems with their Up fitness software.
Jawbone will be opening up their APIs to allow other wearables to upload data to their backend service, including from Windows Phones with for example Sensorcore installed.
In addition, Jawbone will allow device makers to make their own products that communicate directly with the Up system via an open protocol, without being required to make a companion app.
Jawbone is hoping that moving to an open system will increase the use of the app, which includes step-tracking and logging of food and sleep, as well as sharing with friends, and spur consumers to buy its own hardware.
It is not clear if as part of the move Jawbone will port their app to Windows Phone, but we have sent the company an enquiry asking about the same.
