Fitbit’s latest fitness and activity tracker, Fitbit Charge 4, released an update with two major upgrades. The changes to the software version 1.96.29 includes ‘Smart Wake’ and ‘Dynamic GPS’. The device already comes with 24/7 heart-rate tracking, sleep tracking and spotify control.
With the new smart wake feature, your Fitbit will set alarm and wake you up at the most appropriate time when you feel well rested. The aim of the feature is to wake the user up when they are in ‘light sleep’ within 30 mins prior to the scheduled alarm, to avoid disturbing the user when in deep sleep. However, if a more optimal time isn’t identified by Fitbit before the alarm, it will simply go off at its usual time. Smart Wake feature is also available on the Fitbit Ionic and Fitbit Versa series. Another useful new feature is the Dynamic GPS. This mode when enabled, will switch to using your phone’s GPS when nearby and in range to track your route, pace and other stats. Since the fitness tracker cannot use its internal GPS for more than five hours, the shared GPS usage will save battery and give you time for more workouts. However, when a phone is not nearby, the device will go back to relying on its built-in GPS. Read More
