Lots of useful features
The Fitbit Blaze continuously monitors your measured steps, distance, calories burned, active minutes and heart rate. The watch has a wealth of sensors that work with the GPS in your phone and the summer-themed software automatically determines the type of activity you're engaged in and it's automatically recorded. Naturally, the display also tells you the current time, alerts, SMSes, calendar, caller ID, and details of whatever music you're listening to.
