Fitbit Charge features that we love

Before we wrap up this guide and leave you to your thoughts, we want to discuss some of our favourite Fitbit features that really take the smartwatch experience to the next level.

Fitbit Premium: Fitbit premium is a subscription service that helps you stay healthy in multiple ways. This personalised resource within the Fitbit app helps you tailor workout, diet and sleep plans - among other things. It's a one-stop-shop when it comes to your health and wellness.

Smart Wake: Available on both Fitbit Charge 4 and Fitbit Charge 5, the Smart Wake feature uses machine learning to wake you up at the optimal time. When looking after your health is a priority, never underestimate sleep.

Swim tracking: No matter which Fitbit model, it's easy to take it for granted to be able to track your exercise, whether it's outdoor workouts or gym sessions, because Fitbit does it so well. But both the Fitbit Charge 4 and Fitbit Charge 5 are waterproof, and swimming is an incredible workout. While it may not track your heart rate while you're in the water, the swim tracking feature still records your swim distance and completed pool lengths.

The built-in GPS: This may be obvious, but we really like Fitbit's GPS chip. It's always incredibly accurate.
