The Garmin Vivofit is a basic activity tracker that tracks your steps and sleep.
The band has a display that shows you the number of steps you've taken and how many you still need to add to reach your daily goal. Unfortunately the steps tracking is often time inaccurate by adding too many steps.
The device has a battery life of a year, is water resistant and with the push of one button on the device you can sync the Garmin data to your smartphone.
Through Garmin Connect you can sync some data with Apple Health, as well as connect MyFitnessPal.
