Engadget - Jawbone. Fitbit. Microsoft. And now... Basis. If you don't know much about the brand, you really should get up to speed: The company quietly put out one of the best fitness trackers, and now it's a part of Intel. Which means, it's officially one of the big names in health gadgets. Like the previous-generation B1 band, the new Basis Peak can automatically detect when you're exercising or asleep, making it one of the most automated fitness trackers around.
