If you are one of the roughly 38 million Americans who have at some point bought a fitness tracker, you’ve likely noticed some of their flaws. They’re easy to forget, they can often die suddenly, and at times you just don’t want to wear them to a more formal event. Spire is a fitness tracker that manages to avoid all of those downsides.
This simple tag is designed to be attached to the inside seam of any of your clothes; underwear, pajamas, you name it. Once attached, it will silently provide insights on your sleeping, exercise, heart rate, and even breathing. And thanks to an 18 month battery and waterproof build- they’ll never die or get broken. This means that you can get all of the insights you’d get from your run-of-the-mill fitness tracker without even having to think about it. Right now Spire is available in single packs, 3-packs, 8-packs, and 15-packs.
