The Differences?
- Sturdy and Durable Designs
- Versa 3 and Sense Have Loudspeaker
- Fitbit Sense is Most Health Tracker With ECG, Stress and Temprature Tracking
- Battery Life
Each of these three has a sturdy design made of aluminium case and silicone straps that results in a very lightweight smartwatch. However, Fitbit sense has a stainless steel bezel compared to aluminium on both Ionic and Versa 3. Each of these three also supports touchscreen as a means of navigation, but while the Ionic has 3 physical buttons, Fitbit has opted for a touchkey with the new Versa 3 and Sense which some users claim is not very responsive. Personally, I prefer a button to touchkey.
Both Versa 3 and Sense have slight larger 1.58 inches display than Ionic’s 1.42 inches. Moreover, AMOLED display of Versa 3 and Sense is more colourful and vivid than the LCD display of Ionic.
Loudspeaker comes with both Versa 3 and Sense which Ionic lacks. As a result, you can make and receive calls directly from these two, unlike Ionic which lacks this feature. All three smartwatches have music storage, but I can’t really tell if the means of transferring music to Versa 3 and Sense is still via a computer which I don’t find interesting.
One common feature with each of these three is the presence of inbuilt GPS that allows you to track your routes and location without carrying your phone along. That’s a lot of convenience for outdoor workout enthusiasts. Beyond that, each of these three will track your steps, calories, heart rate, count floors climbed with preloaded sport modes.
Now, the difference though, is that Fitbit Sense is the most equipped health tracker than any other Fitbit smartwatch. It comes with ECG that allows you to take an ECG test directly from your wrist. It also comes with an EDA sensor that tracks stress and a temperature sensor. Versa 3 and Ionic lack these features, although you can measure stress from these two on-demand.
Moreover, Versa 3 and Sense come with SpO2 blood oxygen tracking that measures how well your blood absorbs oxygen.
Each of these three has a long battery life that can take you through a couple of days from a single charge. However, the Versa 3 and Sense have slightly longer battery life than Ionic.

Which is The Best?
I’ll say Fitbit Sense is the best choice, it has the most health tracking features than the other two. However, it’s more expensive than Versa 3 and Ionic.
On the other hand, Versa 3 which has a loudspeaker, slightly longer battery life and larger and more colourful display than Ionic, yet priced about the same is a better smartwatch.
