The Blue-Faced Collection

Now that smartwatches are available in a range of styles and
sizes from a number of top companies, shopping for a new one might be difficult
due to the sheer number of alternatives. Remembering that you need to pick a smartwatch
that works with your smartphone is one method to focus your search. While some smartwatches
only function with iPhones, others only function with Android devices.

But it's just the tip of the iceberg. The majority of
smartwatches should allow you to get smartphone alerts and measure your heart
rate, activities, sleep, and GPS. You can actually leave your phone at home
because many of them offer contactless payments and others have cellular or LTE
connectivity.
