Right now, Amazon is offering the Motiv Ring Fitness, Sleep, and Heart Rate Tracker for $159.99. That's 20% off the usual $200 price tag. Today's deal is a match of the historic best price.

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 grey, 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 two days later.

This durable, lightweight ring is waterproof to 165 feet, has a battery life and onboard memory 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. The Motiv can also provide two-factor authentication to help keep you secure, whether while online shopping or checking your email.
