The Samsung Galaxy Watch 7 and the Fitbit Versa 4 both offer advanced sleep tracking features, but there are some differences in the metrics they provide. Here's a detailed comparison of their sleep tracking capabilities:
Samsung Galaxy Watch 7
- Blood Oxygen Levels During Sleep: The Galaxy Watch 7 can track blood oxygen levels throughout the night, which can be crucial for identifying potential sleep issues such as sleep apnea. It has received FDA approval for detecting sleep apnea, making it a valuable tool for monitoring respiratory health during sleep[1][3][9].- Snore Detection: Samsung's watch includes snore detection, which can help users identify if snoring is affecting their sleep quality. This feature requires the watch to be securely attached to the wrist and the phone placed near the head[4].
- Skin Temperature During Sleep: Although not explicitly mentioned in all sources, Samsung's advanced sleep features often include monitoring skin temperature, which can provide additional insights into sleep quality and health[1].
- Sleep Coaching: While not as prominently featured as in previous models, the Galaxy Watch 7 still offers sleep coaching through the Samsung Health app. This involves recording sleep patterns over several nights and receiving personalized advice to improve sleep habits[1].
Fitbit Versa 4
- Personalized Sleep Profile: Fitbit provides a detailed sleep profile that includes daily sleep stages analysis and a smart wake alarm. It uses an accelerometer and photoplethysmography (PPG) to infer sleep stages like deep, REM, and light sleep[2][5].- SpO2 Monitoring: While Fitbit Versa 4 has an SpO2 sensor, it does not use this feature specifically for sleep tracking. Instead, it measures blood oxygen levels during the day or manually upon user request[5].
Key Differences
The Samsung Galaxy Watch 7 tracks blood oxygen levels and snore detection during sleep, which are not standard features on the Fitbit Versa 4. Additionally, the Galaxy Watch 7's sleep coaching and skin temperature monitoring offer more comprehensive insights into sleep health. However, Fitbit is known for its granular sleep stage analysis and personalized sleep scores, which some users might find more detailed and helpful for improving sleep quality[6].Citations:
