Fitbit has quietly released a new activity tracker, but don't expect to buy one yourself -- if anything, it'll be issued to you. The company's new Inspire is a fitness band intended for companies that plan to issue wearables en masse, whether it's your health insurance provider or a just a corporation that wants employees to stay active. It's the definition of no-frills. A basic version doesn't do much more than track activity and deliver phone alerts, while the Inspire HR adds heart rate monitoring and phone-based GPS. There's no price listed, but that's likely to vary from deal to deal. It's the company's cheapest device yet, however.
