The Garmin Vivofit activity tracker is now available to buy, but only at John Lewis, for £100.

The Garmin Vivofit will track your progress, presenting you with goals and reminders so you can keep active and monitor your steps, goal countdown, calories burnt and distance covered. It will also monitor your sleep.

There's an always-on curved display, which will also tell you the time, and Garmin says that the battery will last you over a year and can be replaced by the user.

The Vivofit is water-resistant, so you'll have no worries about wearing it in the rain, but taking things a step further, it's also ANT+ compatible, so you'll be able to use it with heart rate monitors.

In the US there is a pricing option with a heart rate monitor included but John Lewis doesn't offer this just yet. The Garmin Vivofit is available now for £100.
