Smartwatches get all the attention, but smart rings are a great alternative if you’re looking for a more subtle way to track your health and fitness metrics. While there are plenty to choose from, the Samsung Galaxy Ring is going to be a top choice for Android and Samsung device owners, especially since you won’t need to pay any additional monthly fees to use it. And right now, you can score the ring for $100 below its retail price as Samsung, Best Buy, and Amazon all have it on sale.
