Fitbit Charge HR vs. Garmin Vivofit 3
Garmin Vivofit 3 fitness band is better for your training workouts because it pairs wirelessly with most ANT plus enable heart rate monitors and therefore you get spot on calories burned data during your workouts. It also displays your heart rate zone.
Another advantage is that you can go swimming or take a shower with your Vivofit as it is water resistant up to 5ATM. Garmin Vivofit is much more customizable than Fitbit Charge HR. You have the option to set different screens for your device. You can also customize the home screen from the application.
You do not need to charge your Vivofit activity tracker as it is powered by a non chargeable battery. However you will need to replace it after around 12 months. Charge HR on the other hand needs to be charged every 5 to 7 days.
Fitbit Charge HR has a built-in optical heart rate sensor which gives you 24/7 heart rate data. The HR data from an optical sensor is less accurate than an external chest strap HR sensor. However the optical sensor data is better than just having accelerometer data for basic activities.
Both Charge HR and Vivofit 3 can automatically synchronize your workout statistics with the phone app using Bluetooth. Both of these wearable devices have auto sleep and wake detection.
Fitbit Charge HR can detect stairs climbed while Vivofit devices cannot track elevation as they lack an altimeter.
Charge HR has a small call notification smartwatch feature which Vivofit lacks. Vivofit also lacks the silent alarm technology as it does not have a vibration function.
Lastly, Fitbit application is very user friendly and is among the best in terms of usability and it has a great layout. The Garmin mobile app is much cluttered and difficult to navigate.
