The daily activity goal is a good way to find out how active you really are in your everyday life. Here you can choose your typical activity level from three options and see how active you need to be to reach your daily activity goal.
The time you need to complete your daily activity goal depends on the level you have chosen and the intensity of your activities. Age and gender also affect the intensity you need to reach your daily activity goal.

Nokia Healthmate can adjust things like time, position of the hands, what notifications appear on it. Shows/records your activity history, which includes heart rate, sleep cycle, steps, distance. On Android it communicates with Google Fit and underguards MyFitnessPal. It doesn't consume a lot of battery life either, maybe like three percent over a normal charge.
Cons
Con Sleep tracking lacks detail and accuracy
If you are awake for an extended period of time in the middle of the night and then fall back asleep, the fitness tracker may not see the additional hours as part of your sleep.
Con Unattractive and bulky design
The tracker is quite wide and hard to miss, it's not something that can blend in with what you're wearing outside of sport/exercise type settings.
Con Short battery life when using the GPS
With the GPS turned on, battery life goes from around 24 days to 9 hours.
This is likely fine for people who will always have opportunities to charge it after their run. However for anyone hoping to use the GPS for longer activities, such as hiking, that may not be long enough to be useful.
Con Glass is not scratch resistance to keys.
Easy solution is to put either your watch on your other arm, or your keys in the opposite pocket.
