Smartwatches and smart straps are generally worn around the wrists and both indicate the time and contain health and fitness functions (pedometer, tachymeter, sleep monitor, heart rate monitor, etc.). They can also be connected to smartphones via Bluetooth. A smartwatch is a portable device designed to be worn on the wrist. Like smartphones, they use touchscreens, offer apps, and often record heart rate and other vital signs.
A watch with a sapphire crystal screen or, at least, the Corning Gorilla Glass DX+ will have another additional advantage, since it will protect the screen from scratches or any type of damage, even when the watch is hit by a hard object. These devices usually offer a more robust version of a fitness tracker, insofar as they oscillate between a smartwatch that depends on the phone and a standalone fitness tracker, such as a Fitbit.
