I bought this in February when my Fitbit 4 broke. Measure heart rate, distance ,gps, steps , stress management, sleep monitor and many more features. A great unit - selling it because I received a new model. Fitbit 5 works great and it’s a good deal for you! Comes with a beige band in two sizes to fit all and a usb power cord for charging your unit. You will need to download the app to set it up. Easy to use.
