Amazon's health & wellness band is 25% off today

Amazon's most recent wearable device, the Halo is on sale. If you can't afford an Apple Watch or a Fitbit fitness tracker, the Amazon Halo is a great alternative, not just price-wise, but also when it comes to functionality.

Amazon Halo promises to accurately measure and track body fat, allowing users to find ways to improve their body composition. More importantly, Amazon Halo analyzes your sleep patterns, such as how often you wake up during the night. It can also track the intensity and duration of your movement, as well as sedentary time.

And something that few other wearable devices do, Amazon Halo offers to analyze qualities of your voice like energy and positivity to help strengthen communication. Most of these features are offered for free, but if you want more detailed tracking, you'll have to pay $3.99 per month. That will get you body composition, tone of voice analysis, sleep & activity tracking, and much more.
