Fitbit Surge , it the most powerful Fitbit with GPS tracking till now, with real-time workout details and a heart rate details.But it’s stepped up specs and touchscreen LCD make it bigger in size and price. .
It keeps a sleep track but not the quality of sleep.i mean if we are paying a huge ammount of money for this band so it should have some more exciting features .There are lots of app on google playstore which keeps the track of fitness allm
ost everything just for free.Its cost isso expensive i.e22000.i would not recommend to anyone
