Progress lights With the Link’s four LED lights, you can easily track your progress throughout the day. Each light indicates 25% of your goal completion, so you can quickly see how you’re stacking up. The iFit family Everything you do with iFit is connected. This means that all of your stats—whether you’re running with one of our wearables or working out on a piece of iFit ready fitness equipment—sync up to the same cloud. You can find all of your information, safe and secure, in one, convenient place. Auto-activity detection Fitness tracking just got smarter. Now you can change activities without manually switching modes. The Link will automatically detect specific movement patterns like walking, running, and sleeping. *Compatibility Make sure you have the right gear. iFit Link is only compatible with the iPhone® 4S and above, iPod touch® 5th Gen and above, and Android™ 4.3 and above.
