    Looks like a tracker

    Whether you’re a fitness fanatic or just starting out, the Fitbit Charge 3 can help you get a deeper understanding of your body and reach your fitness goals. It tracks your heart rate all day, so you can see the effect of those small changes you make every day – like cycling to work, or taking the stairs instead of the lift. And when it’s time for a proper workout, it can recognise over 15 types of exercise. Want to see how it all adds up? Check how many calories you’ve burned throughout the day.

    Acts like a smartwatch

    The Fitbit Charge 3 doesn’t just help with your fitness goals. It can help you stay on top of your day too. Check the weather to see if you need to take an umbrella to work. Make sure you don’t miss those important meetings, with calendar reminders. And get call notifications when your phone’s nearby. The Fitbit Charge 3 helps you to stay organised and know what’s going on, without having your phone in your hand all day.

    Track your health 24/7

    Use the Fitbit Charge 3 to get to know more about your body, your fitness and your sleep. Find yourself watching TV or playing games on your phone when you should be getting some shut-eye? The Charge 3 will remind you when it's time for bed, so you can make sure you're getting plenty of rest. And it'll even show you how much deep, light and REM sleep you're getting, so you can understand more about your sleep quality. If you're a woman wanting to know more about your monthly cycle, just pair the Charge 3 with the Fitbit app. Track your periods, record any symptoms and check-out the predicted-ovulation calendar. Whoever you are, the Charge 3 will help you understand what your body's up to 24/7.

    Wear it all week

    Don't like wasting your steps while your fitness tracker's charging? The Fitbit Charge 3 has a battery life of up to a week, so you won't be constantly waiting around for it to power up. And that means it's perfect for taking on a short break or hiking trip. Love to get your exercise hit in the pool? No problem - the Fitbit Charge 3 is water resistant up to 50 metres. It comes with small and large wristbands, so you can find your perfect fit and stay comfortable. And whether you're outside enjoying the sunshine or out for a run after dark, the large back-lit, touch-screen display automatically adjusts to lighting conditions so you can easily see how you're tracking at any time of the day.
