Garmin vivio smart

I use the Vivosmart and really like it. It works, it is discreet on the wrist and has some neat features like notifications and music control, as well as being able to work with speed sensors and heart rate monitors.

A smartphone is essential to get at the data and sync with MFP.

However, trackers like fitbit, misfit etc etc also do a worthy job. The real reason I went for the Garmin over the rest is because I use a Garmin Edge cycling computer and can combine data from both devices and MFP into one dashboard.

It should be noted that any wrist based trackers are not completely accurate, and as long as you bear this in mind and look for direction rather than complete accuracy (i.e. not eat back all active calories from tracker, assuming calorie loss is the goal) then all is good.

If your exercise regime is heavily cardio based then something with an integrated heart rate monitor is nice, something like the Fitbit surge or charge HR (the garmin requires a separate purchase of a heart rate strap). If you are a swimmer, then Garmin and Misfit have devices that will track strokes and pool laps.If you are a cyclist then a dedicated cycling computer is the way to go. If you are a runner, then the Garmin forerunner series is good. For multi sport, the garmin vivoactive or misfit shine offer tracking across different activities. If you just need a step counter then there are a multitude of inexpensive devices.
