The Fitbit Sense 2 Advanced Health Smartwatch has been noted for its focus on advanced health features, particularly stress management, with new sensors that monitor physical signs of stress​. Users have found the battery life quite satisfactory, with reports of it lasting almost three full days on a single charge​​. The updated user interface and improved stress-tracking features have also been highlighted as strengths of the device​​.

However, there are some mixed feelings about the Sense 2’s value due to stiff competition and some downgrades from the previous model. While it does offer full-featured health tracking and a handsome design with a battery that can last a week with light use​, it lacks certain functionalities such as Google Assistant, Google Maps, and Google Wallet at launch, which were available in the previous generation. Moreover, there is no music functionality, and the device has moved from a stainless steel case to an aluminum one, which some users view as a downgrade​.

The design is described as comfortable, lightweight, and not prone to catching on sleeves, with a “squircle” shape and an OLED display flanked by chunky bezels. The Sense 2 includes new sensors for taking ECG measurements and has upgraded its EDA sensor to provide continuous monitoring. The device’s straps use a proprietary connector that is simple to use and the watch comes with both small and large bands​.

In terms of software, the Fitbit Sense 2 does not run Wear OS but instead uses Fitbit’s proprietary software, which has been noted to be quite similar to Google’s offerings, with notifications and quick settings accessed with a swipe and customizable tiles. However, the absence of Google Play Store support means users cannot install a variety of apps available on other Android-powered wearables. Amazon’s Alexa comes pre-installed instead of Google Assistant, which may be a downside for users who prefer Google’s voice assistant​.

The overall consensus suggests that while the Fitbit Sense 2 excels in health tracking and design, its day-to-day performance may be hampered for some users by the lack of certain smart features and downgrades from the previous model.


  1. Full-featured health tracking capabilities.
  2. Attractive design and comfortable wearability.
  3. The battery can last up to a week with light usage.
  4. Continuous EDA monitoring and ECG measurement capabilities.
  5. The proprietary software offers a user-friendly interface with customizable tiles.


  1. Absence of Google Assistant; lacks Google Maps and Google Wallet at launch.
  2. Constructed with aluminum rather than the more durable stainless steel used in the previous model.
  3. No onboard music storage or control functionality.
  4. The software does not run Wear OS, limiting app installation options.
  5. Some features like ECG measurements were not initially enabled on review units​.


The Fitbit Sense 2 stands as a significant player in the health-focused smartwatch arena. Its introduction of continuous EDA monitoring for stress and the integration of ECG capabilities represents Fitbit’s commitment to health over general smartwatch features. The week-long battery life is a commendable feat, reflecting an understanding of user convenience in real-life scenarios, where frequent charging can be a nuisance.

However, the Sense 2 faces challenges in a highly competitive market where integration with broader ecosystems, such as Google’s, is increasingly expected. The lack of Google services, particularly Google Assistant, may be perceived as a step back, especially for users entrenched in Google’s ecosystem. Moreover, the switch from stainless steel to aluminum could raise questions about long-term durability and design choices.

In essence, the Fitbit Sense 2 is a device that seems to prioritize health and wellness tracking over the versatility often expected from smartwatches. It’s a product that likely appeals more to health-conscious users who value specific tracking features over a suite of smart functionalities. The choices Fitbit has made with the Sense 2 reflect a strategic focus on health metrics, perhaps at the expense of broader smartwatch capabilities.
