Don't just move more, move smarter with the Fitbit Charge 4 Black. The tracker measures the intensity of your workout based on your heart rate zone. You'll be able to see at a glance whether you've already followed the World Health Organization's advice to exercise 150 minutes in moderate intensity or 75 minutes in high intensity every week. The Fitbit community motivates you, as you can earn badges, share statistics with friends, and compete in challenges. During a run, the Charge 4 registers your distance, speed, and route thanks to the integrated GPS receiver. That means you'll no longer need to bring your smartphone. You can also receive notifications from your smartphone, measure your sleep, and make contactless payments via Fitbit Pay.
In order to use the Charge 4, you need an Android smartphone with Android version 7 or higher. Do you have an iPhone? You need an iPhone 5s or newer with iOS version 11 or higher. The Charge 4 doesn't work in combination with Huawei smartphones.
You can easily wear the watch at night. The sleep mode of the watch dims the display and stops responding to movements. You'll also no longer receive notifications. In the morning, you'll receive a report in the app. You can see how long you were in each sleep phase and what your sleep score is. You'll also receive tips for a better night's sleep.
If you're going to a bootcamp class, you can leave your phone and wallet at home. Afterwards, you'll be able to buy a bottle of water with your watch via Fitbit Pay. Check whether your bank supports the mobile payment service Fitbit Pay under the 'required bank account'.
Note: you won't receive a connector. Do you want to charge the watch via a power outlet? Use the power adapter of your phone charger or order a charger adapter.
This watch is suitable for a wrist circumference of 15 to 17cm.
