It probably won't excite you, but it could be Fitbit's most important device in the near future. While Fitbit recently returned to profit thanks to its Versa smartwatch, company chief James Park told CNBC in an interview that his business increasingly relies on large scale deals. A simple tracker like the Inspire makes those kinds of deals more appealing, even if people might not relish the thought of wearing a budget tracker to please their employers or lower their insurance premiums.

The tech firm might not have much choice given the competition. Multiple insurers are already offering the Apple Watch as a perk to active customers, for starters. While Apple's hardware is in a different price class, it could still shut Fitbit out of important deals. The Inspire could be harder to resist for companies that want to promote healthy living, but don't want to pay a lot in the process.
