Detailed Feature Comparisons
Design and Construction
Both watches feature an identical 1.58-inch AMOLED display with the same resolution, providing vibrant visuals and responsive touch interaction. The Sense 2 stands out slightly with a stainless steel ring, which supports its additional health sensors. Versa 4 uses a simpler aluminum-only design, making it lighter but slightly less premium in look.
Health Monitoring
Fitbit Sense 2 includes advanced health tracking tools like an EDA sensor for stress management, ECG app for heart rhythm monitoring, and skin temperature tracking. These features are absent in the Versa 4, which focuses on core health metrics such as heart rate, SpO2, and general sleep and activity tracking.
Fitness and Exercise Tracking
Both devices support 40+ workout modes, built-in GPS, and real-time pace and distance tracking. The performance in this category is nearly identical. However, Sense 2 offers additional motivation for wellness-focused users with its stress and mindfulness features.
Stress and Sleep Management
Sense 2 is built with a focus on stress detection using a continuous EDA sensor, providing real-time alerts and stress management tools. Versa 4 offers sleep tracking and basic stress insights, but it lacks real-time stress notifications and detailed mood logging tools available on the Sense 2.
Smart Features
Both devices run Fitbit OS and include Google Wallet, Google Maps, and smartphone notifications. Neither supports third-party apps or has a built-in speaker, and both rely on Alexa for voice commands. Google Assistant support has been removed from both models.
Battery and Charging

Performance and Usability
Day-to-day performance is fluid and consistent on both devices. Navigating menus, checking notifications, and using the built-in apps feel responsive. Sense 2 may use a bit more power due to its health tracking sensors, but battery life holds steady in normal use.
