Which is a Better Smartwatch?
- DESIGN:
- HEALTH TRACKING:
- MEDIA:
- BATTERY LIFE:
- NOTIFICATIONS:
Starting with the design, one common aspect is that each of these two smartwatches is very lightweight, compact, and sturdy. So, you can expect a comfortable wear all day long without feeling the need to remove the watch.
Watch 6 is available in two sizes; 44mm and 40mm, while the 44mm is bigger than Fitbit Sense, its same size as the 40mm. It is good to know that Apple has remained consistent with the slim design that sees the Watch 6 only 10.7mm thick compared to 12mm of Fitbit Sense.
Looking at the materials used in the making of these two, while Fitbit Sense is only available in aluminum material with a stainless steel bezel and silicone straps, Watch 6 comes in three different materials; aluminum, stainless steel, and titanium case material paired with silicone loop bands.
As per the display, Watch 6 has a slightly bigger display than Fitbit Sense, both smartwatches have a touch-sensitive screen. Fitbit Sense has a haptic button, while Watch 6 has one physical button and a digital rotating crown with a haptic feedback mechanism that certainly makes it very easy to access.
Overall, as per design, Watch 6 has a more sophisticated design than Fitbit Sense.
Both Watch 6 and Fitbit Sense are sold and marketed as fitness companions that can help you stay fit and reach more fitness goals. Each of these two tracks all the basics that include complete sleep tracking in stages, track your heart rate and will show your resting and heart rate range. Each of these two will also track your steps, calories, and floors climbed. There are also preset sport modes on both smartwatches which will allow you to choose your favorite sports activities.
However, Watch 6 is a more comprehensive fitness smartwatch than Fitbit Sense going by the number of activities it can track. Both smartwatches feature blood oxygen tracking, although, the blood oxygen tracking feature on Fitbit Sense is not a complete one as it only tracks your blood oxygen at night and displays your blood oxygen levels via Fitbit’s Signature watch face, meanwhile, Watch 6 allows you to check your blood oxygen levels on request via the blood oxygen app.
Watch 6 and Fitbit Sense feature ECG tracking which allows you to take ECG test directly from your wrist, this can help you detect irregular heart rhythms which is a common sign of atrial fibrillation. You’ll find a handwashing app on Watch 6 which reminds and guide you through washing your hands, while the “Cue watch face” is Fitbit’s way of reminding and guiding you to washing your hands.
The Cellular model of Watch 6 features incidental fall detection, international emergency calling that allow you to call emergency contacts almost anywhere in the world.
You can store your media files on any of these two smartwatches. While Fitbit allows you to download Deezer playlists, Pandora stations, and control Spotify playlists on your phone, Watch 6 has a far bigger storage capacity that allows you to store more of your favorite tracks on the watch. It’s worthy to note that, you can’t add your personal music to Fitbit Sense which is very unfortunate.
Furthermore, both Watch 6 and Fitbit Sense have loudspeakers and microphones. However, while you can make and receive calls directly from Watch 6, you can’t make and receive calls on Fitbit Sense, you can only reject or answer a call that must continue on your phone. Perhaps in future updates, Fitbit Sense will be able to make and receive calls.
While Siri allows you to use your voice to do simple tasks, Fitbit Sense features Alexa with Google Assistant to be added in the future.
If there is one aspect where Fitbit Sense floors Watch 6, it’s in the battery life aspect. While you can get up to 6 days long battery life with Fitbit Sense, Watch 6 can bearly last a full day which is very disappointing, pointing to the fact that you have to charge it every day to stay connected.
In terms of managing notifications, you can easily manage notifications on any of these two smartwatches. Both smartwatches will allow you to reply to notifications with your voice, emojis, and preset replies. However, Watch 6 offers more ways to stay connected as you can type your reply which isn’t possible with Fitbit Sense.
So, Which Should You Buy?
Apple Watch Series 6 is clearly a better smartwatch than Fitbit Sense, it’s a more comprehensive fitness smartwatch with a higher storage capacity and more features, and also has a more sophisticated design.
Meanwhile, Fitbit Sense which is compatible with both Android and iOS devices is cheaper, yet, an advanced fitness smartwatch with a long battery life that lets you go multiple days from a single charge.
