Right now, Best Buy is offering the Motiv Ring Fitness, Sleep, and Heart Rate Tracker for $169.99. That's $30 off the usual $200 price tag and matches the best price we've ever seen on it, besting Amazon's offer by $5. The deal is only available for today as part of Best Buy's daily deals.

Note that initially, you'll receive a sizing set. You'll use it to find your perfect fit and customize the look. Color options include silver, rose gold, and black. Once you know what size and color is best for you, you'll let the company know, and they'll ship it to you. You'll receive your ring a couple of days later.

This durable, lightweight ring is waterproof to 165 feet, has a battery life that spans three days, and charges in just a couple hours. The free Motiv app for iOS and Android displays your personalized activity, sleep, and resting heart rate in an intuitive newsfeed-style interface. Just tap each card to see more details. You can sync that data with Apple Health or Google Fit depending on your platform of choice, too. The Motiv can also provide two-step verification to help keep you secure, whether while online shopping or checking your email. For more details and an in-depth review, head to Android Central.
