Fitbit and Jawbone are two of the biggest players in the fitness tracking device industry ever since both companies released activity trackers in 2011. The Fitbit Charge HR and the Jawbone UP3 are the top contenders for your wrist-space in their category, and both offer great features. But which is the better activity tracker? Do they offer value or are they glorified pedometers? Follow us as we compare and check out the features of both devices that make each worth buying.


The Fitbit Charge HR tracks activity, heart rate, and sleep. The Charge HR features sensors that enable it to monitor your steps, distance traveled, elevation climbed, activity time, and calorie expenditure. The device also monitors your sleep and tracks sleep quality and sleep pattern. It also comes with a silent alarm that nudges you awake when you are in the light stage of your sleep cycle, which means you are close to waking up naturally.

The Jawbone UP3 also provides activity and sleep monitoring and tracks your steps, distance traveled, stairs climbed, and calories burned. Like the Charge HR, it also monitors light, REM, and deep stages of your sleep.

The Fitbit Charge HR monitors heart rate with the company’s proprietary PurePulse heart rate monitoring technology which provides all-day heart rate monitoring including resting and active heart rate tracking data. This makes the Charge 2’s calorie burn and sleep monitoring data highly accurate.

The Jawbone UP3 tracks heart rate using bio-impedance tracking which is a system of four sensors. The sensors track breathing rate, resting heart rate, skin temperature, and galvanic skin response to give a clear picture of your health and fitness.

The Fitbit Charge HR has 5-day battery life on a single charge while the Jawbone UP3 comes with seven days of battery life on a single charge.

Style and Functionality

The Fitbit Charge HR is offered in three sizes and four colors so you can always choose your most preferred or combination of colors. The Charge HR looks like a smartwatch and comes with a wristband and most importantly an LCD screen that shows your stats in real-time. The device syncs with your smartphone through Bluetooth and is compatible with Android and iOS platforms. The device also shows notifications for calls and text.

On the other hand, the Jawbone UP3 comes in bracelet form and is available in two colors. It doesn’t have a screen, but a tiny light notifies you when you have a call or text.

Both devices come with a companion app that shows you a detailed analysis of your stats and let you set goals, enter competitions and earn badges as well as share your progress with others.

Unfortunately, both devices don’t offer water-resistance which means you can’t take them into the shower or pool. They also lack GPS, which is a no-brainer for runners. So, if you aim to use your fitness tracker for running or swimming activities, both the Fitbit Charge HR and the Jawbone UP3 are not ideal for you.

Precision (Accuracy)

The heart rate monitoring of both trackers are highly accurate, owing to the advanced tech of their HR sensors but the Jawbone appears to be leading due to its bio-impedance sensors. Also, the UP3 edges the Charge HR in sleep tracking, again due to its highly sensitive bio-impedance sensors. All in all, both are great devices to have and deliver on their manufacturer’s promises. But like every machine, don’t expect them to be 100 percent accurate.
