The UP3 wearable maker claims Fitbit has been systematically plundering proprietary data by hiring Fitbit employees who allegedly stole confidential information.
Affordable Jawbone UP2 fitness tracker also gets announced to replace 2013's Up24 model; this unit lacks heart rate monitor, though.
The Mountain View, CA-based search giant is considering making a "strategic investment" in Jawbone to grow its presence in the wearables market.
At the moment, the site features only 10 different products and services, such as Fitbug's Kiqplan training service, Sleepio and a SmartThings Kit for Jawbone.
Designed for any group of 10 or more participants, UP for Group has already been tested with large companies, smaller organizations and professional groups.
The former supersedes the current Up24 fitness band, adding new features and capabilities to the mix, while the latter provides fitness tracking for the masses.
The Jawbone UP platform and app will be able to incorporate health and fitness data from any gadget, whether it's made by Jawbone or not.
The UP Insight Engine will now give you suggestions on how you can improve your overall health, incorporating what you've eaten, sleeping, as well as workouts.
The patent describes how the system would use a number of sensors to tell the user how best to place the device to measure body fat percentage.
The Automatic+Jawbone integration works on both iOS and Android, and the UP users can add Automatic from the Jawbone App gallery.
