Samsung Galaxy Watch Active 2 vs Garmin Vivoactive 4: The Difference


Let’s start with the similarities, both Active 2 and Fitbit Sense are very compact and lightweight. So you can wear any of these two smartwatches comfortably all day long without feeling the need to remove them. I could wear the Active 2 all day long and the silicone straps doesn’t irritate my skin. Although, it’s advisable to always remove the band once in a while.

These two are also very durable, the cases are made of aluminum, while the straps come in silicone. Although, Active 2 is slimmer than Fitbit Sense.

Secondly, the display of each of these two is powered by AMOLED which offers a very colorful and interactive viewing experience. However, while active 2 has a digital rotating bezel that allows you to navigate the device effortlessly alongside 2 physical buttons by the side and touchscreen support, Fitbit Sense relies on the touch-sensitive screen and a haptic button by the side to access the device. I haven’t had the best experience with the haptic button as it can be very frustrating and annoying.

Since each of these two is rated 5ATM, it’s waterproof up to 50 meters, so you can wear both Active 2 and Fitbit Sense for swimming.


Both Active 2 and Sense allow you to store music on the watch, its same 4GB storage capacity. However, while you can add your personal music to Active 2, you can’t do that on Fitbit Sense.
