Fitbit Charge 3 vs Gear Fit 2 Pro: Their Differences and Similarities


Want an option that has a bigger display? If so, I would suggest you get the Samsung Gear Fit 2 Pro and not the Fitbit Charge 3.

Gear Fit  2 Pro features a bigger screen display measuring 1.5 inches whereas Fitbit Charge 3 has a smaller screen display that measures 0.96 inches.

Even though the display on both watches is AMOLED the one on the Samsung Gear Fit 2 Pro looks more luxe thanks to its 216 x 432 pixel resolution.

Fortunately, both watches feature strong Gorilla Glass 3 display that is touchscreen and easy to use.


Both Fitbit Charge 3 and Gear Fit 2 Pro feature a heart rate monitor, with the HR monitor the watches will learn about your heart’s health and share data on their respective companion app.

Want an option that will keep track of blood oxygen levels? Consider Fitbit Charge. Fitbit Charge 3 comes with the SpO2 sensor which is responsible for tracking blood oxygen saturation. Unlike the Fitbit Charge 3, the Samsung Gear Fit 2 Pro does not have a SpO2 sensor and hence can’t monitor the levels of oxygen in the blood.

Cyclists and runners would love to keep track of routes while cycling and running respectively. Only a watch with a GPS sensor can help cyclists and runners keep track of their routes. Gear Fit 2 Pro has a built-in GPS sensor that helps keep track of routes. Fitbit Charge 3 does not no have its own GPS sensor but can share that of your phone to track routes.

We also have accelerometers on the Fitbit Charge 3 and Samsung Gear Fit 2 Pro. Fitbit Charge 3 and Gear Fit 2 Pro can track steps with the accelerometers.

Other sensors you will only find on Gear Fit 2 Pro and not on Fitbit Charge 3 include a gyroscope and barometer.

Sensors you won’t find on both Samsung Gear Fit 2 Pro and Fitbit Charge 3 include ECG, cadence, compass, perspiration sensor, and temperature sensor.


Fitbit Charge 3 can neither store nor stream Spotify music because it has no storage and can’t support Wi-Fi. Gear Fit 2 on the other hand can connect to a Wi-Fi network and let you stream music from music platforms such as Spotify and YouTube. In addition, Samsung Fit 2 also features an internal storage (4GB) that will let you store your favorite songs for offline playbacks.

Activity Tracking

Most of the activities tracked by Fitbit Charge 3 and Samsung Gear Fit 2 Pro are similar.

For instance, the Gear Fit 2 Pro and Fitbit Charge 3 will keep track of your sleep, heart rate, calories, steps, elevation, and more. Activities on both watches are detected automatically.

In addition, you can keep an eye on your swim workouts with Fitbit Charge 3 and Gear Fit 2.

Water Resistance

There is no difference in water resistance – both Charge 3 and Samsung Fit 2 feature a 5ATM water resistance rating.

The 5ATM resistance rating means the watches can be submerged up to 50 meters in water and still come out functional.

Unfortunately,  water resistance on both watches is not permanent but can be retained for long by avoiding soap, lotion, shampoo, detergent, and more.


Fitbit watches including Charge 3 don’t support Wi-Fi. Buy the Gear Fit 2 Pro if you want a watch that connects to Wi-Fi. With the Wi-Fi connection Gear Fit 2 Pro will directly download firmware updates as well as stream Spotify and YouTube music.

Fitbit Charge 3 and Samsung Gear Fit 2 Pro connect to the phone through Bluetooth. Even so, the Bluetooth version of the Gear Fit 2 Pro is newer than that of the Fitbit Charge 3. The more recent the Bluetooth version the faster the data transfer!

Samsung Gear Fit 2 Pro and Fitbit Charge 3 feature Bluetooth versions 4.2 and 4.0 respectively.

I like both Fitbit Charge 3 and Samsung Gear Fit 2 Pro because they can connect with Android and iOS devices.

Unfortunately, Gear Fit 2 and Fitbit Charge 3 don’t support ANT+, Galileo, NFC, and cellular connectivity.

Battery Life

Both watches come with good battery life but the Fitbit Charge 3 is more better. On a complete charge, the Fitbit Charge 3 can last for 7 days, on the other hand, the Gear Fit 2 Pro will only keep charge for 3 days.


The Samsung Gear Fit 2 Pro watch is more expensive so, consider Fitbit Charge 3 if you want a more affordable option.
