Getting a good night’s sleep is essential for both physical and mental well-being, but understanding how well you actually sleep can be challenging without the right tools. That’s where sleep trackers come in. These devices help you monitor your sleep patterns, identify sleep disturbances, and track your overall sleep quality. Whether you’re struggling with insomnia, looking to optimize your rest, or simply want to learn more about your sleep habits, a good sleep tracker can be the key to better nights.
Here’s our roundup of the Top 5 Sleep Trackers That Really Work in 2025:
1. Oura Ring (Generation 3)
Best for Comprehensive Sleep and Health Tracking
- Tracking Metrics: Sleep stages (light, deep, REM), heart rate, body temperature, activity levels, respiratory rate
- Battery Life: 7+ days
- Connectivity: Bluetooth (syncs with mobile app)
- Price: ~$299
Why It’s Great:
The Oura Ring is one of the most advanced sleep trackers on the market, offering in-depth analysis of your sleep stages (light, deep, and REM), as well as other vital health metrics like heart rate variability, body temperature, and activity levels. Unlike bulky wearables, the Oura Ring is a lightweight, comfortable ring that you wear 24/7, making it an excellent choice for sleep tracking without interfering with your lifestyle.
What Could Improve:
While it offers exceptional data, the Oura Ring doesn’t feature a screen for real-time feedback. You’ll need to use the mobile app to access your sleep metrics, which may not be as convenient for some.
2. Withings Sleep Tracking Mat
Best for Non-Wearable Sleep Monitoring
- Tracking Metrics: Sleep cycles (light, deep, REM), snoring, heart rate, sleep score
- Battery Life: No battery (plug-in mat)
- Connectivity: Wi-Fi (syncs with Health Mate app)
- Price: ~$129
Why It’s Great:
For those who prefer not to wear a device to bed, the Withings Sleep Tracking Mat is an excellent option. It’s placed under your mattress and monitors your sleep cycles, snoring, and heart rate. It also provides a sleep score based on the quality of your rest. It’s especially useful for those who want an unobtrusive, non-invasive way of tracking their sleep patterns.
What Could Improve:
While it’s great for those who prefer not to wear a tracker, it’s not suitable for people who move around a lot during the night. The mat might not be as accurate if your sleep position shifts frequently.
3. Fitbit Charge 6
Best for Wearable Sleep Tracker with Comprehensive Health Features
- Tracking Metrics: Sleep stages (light, deep, REM), heart rate, SpO2, stress levels
- Battery Life: 7+ days
- Connectivity: Bluetooth (syncs with Fitbit app)
- Price: ~$179
Why It’s Great:
The Fitbit Charge 6 offers advanced sleep tracking that includes monitoring of sleep stages (light, deep, REM) and heart rate variability. It also measures SpO2 levels (blood oxygen) to detect any potential breathing disturbances, such as sleep apnea. The device comes with a range of other health features, including activity tracking, stress management, and a stress-relieving guided breathing feature.
Fitbit’s app offers easy-to-understand data and insights, including Sleep Score that gives you a quick overview of your sleep quality.
What Could Improve:
Some users have reported that the Fitbit Charge 6 can be a little bulky for sleep comfort, particularly for people who prefer lighter or less intrusive wearables.
4. Whoop Strap 4.0
Best for Athletes and Active Individuals
- Tracking Metrics: Sleep stages, recovery, heart rate variability, respiratory rate, activity tracking
- Battery Life: 5 days
- Connectivity: Bluetooth (syncs with Whoop app)
- Price: ~$30/month subscription
Why It’s Great:
The Whoop Strap 4.0 is designed for fitness enthusiasts and athletes but is highly effective for anyone interested in optimizing their sleep. It tracks your sleep stages in-depth and provides a Sleep Coach feature that adjusts based on your recovery and activity levels. The heart rate variability (HRV) and respiratory rate tracking also help you understand how well you’re recovering overnight.
The Whoop Strap 4.0 is a non-display wearable that doesn’t need charging every day, making it extremely convenient for long-term use.
What Could Improve:
The Whoop Strap 4.0 requires a monthly subscription, which may not be appealing to those who want a one-time purchase tracker. Additionally, it doesn’t have a screen, which means all data is available through the app.
5. Garmin Vivosmart 5
Best for Value Sleep Tracker with Solid Fitness Features
- Tracking Metrics: Sleep stages (light, deep, REM), stress, body battery
- Battery Life: Up to 7 days
- Connectivity: Bluetooth (syncs with Garmin Connect app)
- Price: ~$130
Why It’s Great:
The Garmin Vivosmart 5 provides a sleek, lightweight design while delivering solid sleep tracking features, including analysis of sleep stages (light, deep, REM) and stress levels. The Body Battery feature tracks your energy reserves throughout the day and helps you understand how well your sleep affects your overall well-being.
The Garmin Connect app is very user-friendly and provides an easy-to-read sleep score and detailed metrics, perfect for those looking for value without sacrificing quality.
What Could Improve:
The Garmin Vivosmart 5 is a basic fitness tracker without the advanced features of more expensive wearables, such as blood oxygen tracking or a built-in GPS for runners. It’s a great option for general sleep tracking, but may not be as detailed as other devices if you’re looking for more comprehensive health metrics.
