Movea partnered with Texas Instruments and Xm-Squared to create the G-series, what the company is calling the most accurate wristband tracker yet. The device detects posture, and tracks day-to-day activity, sports workouts, and sleep. Movea says that in tests, the wristband makes remarkably few errors in sleep tracking and step counting and is more than 95 percent accurate in knowing what mode of transportation a person is currently engaged in. It can even predict how the user will move next. In a statement, the company said the wristband is available, but it doesn't appear to be available for purchase on Movea's website.
