This activity bracelet is light weight, easily adjustable and suited to wear 24/7. The Loop displays your activity on the screen and makes sure you are reaching your goals with feedback about your daily, weekly, and monthly activity. It’s waterproof, and even measures your activity when swimming; and although it doesn’t have an inbuilt heart rate monitor, it is easily connectable to the Polar H7 heart rate monitor. Similar to other Polar trackers, the Loop can connect to Polar Flow so you can track your activity and see it as an overview, and also connects to popular apps such as MyFitnessPal so you can sync your food intake and activity for a more accurate direction of how to improve. The battery life is roughly 5 days with continuous use, and is easily rechargeable with a USB cable- and the Loop will tell you when it's running low so you know when you need to charge- no flat batteries here!
