How do the sleep tracking capabilities compare between the Versa 4 and Sense 2

Similarities:
- Both devices provide detailed sleep tracking, including sleep stages (awake, REM, light, and deep sleep), Sleep Score, and Sleep Profile. The Sleep Profile uses multiple metrics to analyze sleep patterns and even assigns a "sleep animal" based on your habits[2][6].
- Both models support automatic sleep tracking, which means you don't need to manually start or stop tracking each night[5].
- Both devices offer features like smart wake alarms and do-not-disturb modes to enhance sleep quality[1][3].

Differences:
- Advanced Sensors in Sense 2: The Sense 2 includes a skin temperature sensor, which can provide additional insights into sleep quality by monitoring body temperature changes. This feature is not available on the Versa 4[4][8].
- Stress Management: While both devices offer stress management tools, the Sense 2 has more advanced stress tracking capabilities, including a cEDA sensor that measures changes in skin conductivity to detect stress levels. This feature is not present in the Versa 4[4][8].
- Detail and Consistency: Users have reported that the Versa 4 sometimes provides less detailed sleep data if the device is not fitted properly or if the user sleeps in a position that interferes with heart rate monitoring[5]. The Sense 2, with its additional sensors, might offer more consistent and detailed sleep data.

Overall, both devices are excellent for sleep tracking, but the Sense 2 offers more advanced features, particularly with its skin temperature and stress management capabilities. If you prioritize detailed sleep insights and advanced health monitoring, the Sense 2 might be the better choice. However, if you're looking for a more affordable option with solid sleep tracking, the Versa 4 is still a strong contender.
