Fitbit Sense vs. Apple Watch Series 6 Two worthy wearables

When it comes to choosing between the Fitbit Sense and the Apple Watch Series 6, it will come down to what type of smartwatch experience you're seeking. These two devices offer many similar features, but they're also different in some very important ways. It might seem obvious, but if you're an iPhone user, the Apple Watch Series 6 will offer the most seamless experience.

Those who are seeking the newest technology and most advanced features for tracking your health and fitness will probably fall head over heels with the new Fitbit Sense. The stand-out features are the new EDA and ECG sensors along with a new skin temperature sensor. It's also the more affordable option and offers significantly better battery life than the Apple Watch Series 6. However, Apple isn't trailing too far behind this time. It also offers blood oxygen monitoring, an ECG sensor, and native sleep tracking.

The first thing you'll notice about the Fitbit Sense is that it remains true to the company's well-known squircle design. A closer look will show some attractive upgrades. The case is made of aerospace-grade aluminum and stainless steel with a biosensor core to provide users with a polished, high-tech look.

Another major design change, which can also be found on the new Versa 3, is the introduction of the new infinity bands, which are geared toward comfort and flexibility. The convenient quick-release attachment makes it much easier to swap out interchangeable bands when you want to try out a new look. Unfortunately, this new system is not compatible with any of the company's previous bands.

While there are a lot of new features on this health-focused watch, you'll also enjoy a fair share of familiar features. The Fitbit Sense is similar to the Versa 3 in many ways. You'll have 20+ goal-based exercise modes, 24/7 heart-rate tracking, sleep monitoring, female health tracking, Fitbit Pay, and Amazon-Alexa as well as Google Assistant.

You also have a built-in mic and speaker, which allows you to take Bluetooth calls on your watch and hear voice assistant responses. Some of these perks weren't enabled at launch, but a new update activated Google Assitant, audible replies with Alexa, voice calls, and much more.

The design isn't the only improvement. The Fitbit Sense offers the first electrodermal activity (EDA) sensor on a smartwatch. This feature will measure electrodermal activity responses, which can be accessed by placing a palm over the face of the device. Watch as your device detects small electrical changes in your skin's sweat level. You'll get a better understanding of how your body responds to stress. Take advantage of on-wrist and in-app stress management tools to track your progress and start living a healthier, happier life.

The Fitbit Sense has the company's latest PurePulse 2.0 technology with a new multi-path heart rate sensor.

The Fitbit Sense has the company's latest PurePulse 2.0 technology with a new multi-path heart rate sensor and updated algorithm, which will deliver advanced heart rate data. This technology supports another heart health feature: personalized high and low heart rate alerts. Another new perk is Active Zone Minutes, which is a newer Fitbit feature that alerts you when you've reached your personalized target heart rate zones during exercise.

There's also a skin temperature sensor that will detect changes that may be a sign of illness, a fever, or a new menstrual phase. Additionally, there's a new electrocardiogram (ECG) sensor that will analyze your heart rhythm for signs of atrial fibrillation (AFib). This feature can be accessed by holding your fingers on the corners of the watch and staying still for 30 seconds. You'll receive a reading that can be downloaded and shared with your physician.

The Apple Watch has come out with a similar design year after year. It always has some new additions or improvements. This model is available in two case sizes: 40 and 44mm. The new Apple Watch Series 6offers some striking new color choices, including blue, red, gold, and graphite. You'll have your pick of aluminum, stainless steel, or titanium finishes. Both models are compatible with interchangeable bands. The Apple Watch Series 6 comes with a new S6 processor, which makes the device run smoother and for longer. In fact, the company says that it runs 20% faster than the Series 5.

There are some new features that put the Apple Watch Series 6 in a perfect position to compete with the Fitbit Sense. Previously, it lacked monitoring for blood oxygen saturation (SpO2) levels and a native sleep tracking app. Fortunately, Apple has added them both into the new edition. You also get an always-on altimeter that will continuously track your elevation changes in real time, both indoors and outdoors.

The Apple Watch Series 6 introduces an all-new service called Apple Fitness+.

Many users will appreciate the improved focus on fitness, too. The Apple Watch Series 6 introduces an all-new service called Apple Fitness+, which features new workouts that can be accessed from various Apple devices. You'll be able to view your real-time metrics during the workout session.

The bad news is that battery life continues to be quite disappointing. You'll still have the usual 18 hours of battery life, which pales in comparison to the six days offered by the Fitbit Sense. With that said, there are some areas where it succeeds. For example, the Apple Watch Series 6 offers endless options for third-party app support that will enhance your smartwatch experience.

On that note, this wearable is also ideal for users who are solely focused on smartwatch features. You have optional LTE connectivity, which allows you to use all aspects of your device without your phone being present. Whether you're accessing apps, making a call, or streaming music, you can do it all. The built-in GPS and compass make it easy to navigate unfamiliar areas. You have access to emergency calls as well. It offers mobile payments with Apple Pay. When you have a question, Siri is available to help.

While these two smartwatches deliver some of the same benefits, it's the differences that will guide you to your ultimate decision. If you've been picky about choosing a wearable because you want to get your money's worth in terms of health and fitness features, the Fitbit Sense may be the perfect solution. The new ECG, EDA, and skin temperature sensors take your health tracking to the next level. You also get Active Zone minutes, improved heart-rate monitoring, longer battery life, and more voice assistant options.

The Apple Watch Series 6 has definitely stepped up its game with health/fitness features, including the blood oxygen sensor and the built-in sleep tracking app. It's also offering Apple Fitness+. For a limited time, new users will get three months free when they purchase an Apple Watch Series 3 or later. As you might've gathered, this is the better choice for Phone users. The good news is you have some new perks to look forward to as well. Be prepared to pay more for it (especially if you choose the larger model or you add LTE connectivity) and you'll need to charge it daily.
