Perfect fit

vivosmart 4, around £99.99, Garmin

This slim wristband greets you each day with a personalised step goal, then displays your progress, measuring floors climbed, calories burned, intensity minutes and more. It can track outdoor walks and runs, and offers sleep monitoring, stress tracking and heart rate. It has a battery life of up to seven days, and it can also be used in the shower and pool.

We love: The Relax Reminder feature, turned on in the Garmin app. If your stress level is elevated, it will encourage you to relax for a moment.
