I love the Fitbit app and is very comprehensive and detailed and is easy to follow. The screen on the Charge 5 is excellent and the glass
is scratch resistant. It is light, smooth and unobtrusive, and therefore there is no issue wearing 24×7; capturing all nocturnal activity!!!!!!! If you are going to invest in your health this is a great tracker. I am sure there are other equally as excellent trackers out there but you won’t have wasted your money, especially if you pick it up at one the Amazon sale days or buy a second hand one from the buy options.
