I had a Fit-bit versa 2 for Christmas and i just love it so thought id sing its praises.
Apart from doing the usual counting steps , it tracks your sleep so you get to see how much time you spent in the various sleep stages Rem,Deep,Light, telling you what yours was like and explaining what each means and if you get enough quality sleep,
Also a really handy addition which i dont believe is on any other watch device is your breathing rate is monitored throughout the night and a graph tells you if you are likely to suffer from sleep apnea which is really useful for those not sure . 10 out of 10 Fitbit worth every cent
