    Record your exercise and check your heart rate

    Whether you're cycling to work, walking to the shops or doing a full-blown workout, the Alta HR tracks it all. It automatically records your exercise, and even keeps track of your daily steps and calories burned. And you can even check your heart rate, with PurePulse.

    Track your sleep and wake up peacefully

    A healthy lifestyle isn't just about exercise and burning calories. Sleep matters too. So the Alta HR automatically tracks your sleep, to give you a more rounded picture of your health. It'll show you how much time you spent in light, deep and REM sleep, so you can understand your sleep quality. And when it's time for your day to start, your Fitbit will wake you up peacefully with a silent alarm.

    Stay on top of your day

    Ever missed an important call while you were on a run? Or turned up late to an event because your workout lasted longer than you expected? The Alta HR sends smartphone notifications straight to your wrist, so you can keep on top of things, even when you're working out. Having a slow day? Your fitness tracker can send you friendly Reminders to Move, to encourage you to reach an hourly goal of 250 steps. So whether it's a day in the office or boxset marathon on the sofa, you can still keep up with your fitness goals.

    Keep going for longer

    Feel like your steps are going to waste when you've taken your tracker off to charge it? The Alta HR has a battery life of up to seven days, so you'll never waste a workout. It means you can track your movements all day and night too, so you can get a better view of your health. And the Alta HR is Fitbit's slimmest design yet, so it's comfortable enough to wear all day. You can even switch up the design with interchangeable bands to match your look.
