The basis band by Basis Science is a very technologically advanced fitness tracker with a watch style. The watch itself looks like a basic digital watch but turn it over and there are six sensors that monitor biometric stats through the skin. The band is splash resistant, making it safe to wear out in the rain or the shower. It offers motivational fitness advice along with providing stats on everything from heart rate, steps taken and even measures how well and how long the user sleeps each night. The lithium powered battery can hold a charge for up to four days.
