Almost everything you will do with the VivoActive 3 Music will be with the touchscreen. The way this works is this.
You have a main “screen” which is the watch face. This is highly customisable, but in its basic incarnation is the screen where you see the current time and date.
From this screen you can navigate through a series of different screens – called “widgets” – by swiping up and down. Widgets can be added/moved/removed and the standard ones are: music controls, calendar, phone notifications, rest index, weather, floors climbed, chart of heart rate in the previous 4 hours, last sport activity, weekly active minutes, daily summary, steps for the day… you get the idea.
Swiping left to right equals a “back” button, while a long press on any given screen (widget) opens the settings for that particular widget and for the watch itself.
Last, the physical button at 3 o’clock. This button starts or pauses/stops the tracking of an activity. So if you want to start a run you’ll have to press the button, select “Run” (scrolling and clicking with the touchscreen) and once it has locked on the sensors (heart rate and GPS) you can press the button again to start the run. Pressing the button again pauses the activity, but if you tap on the big red square on the screen, you will stop the activity. The watch will then ask you if you want to save the activity or not.
I always run with automatic laps of 1km and never use the manual lap function. If you do want to use it, you’ll have to double tap on the screen to mark the end of a lap and the beginning of another one.
