If you’re serious about optimizing your sleep and recovery, you’ve probably come across the Whoop Band 4.0 and Oura Ring 4. They are well known fitness trackers, but what about tracking sleep. Both devices promise to deliver deep insights into your sleep patterns, recovery levels, and overall well-being. But which one is better for sleep tracking? And more importantly, which one is right for you?
I’ve spent months researching sleep trackers, and in this article, I’ll break down the differences, key features, and real-world performance of the Whoop Band and Oura Ring—helping you make an informed decision.
Whoop Band 4.0: A Deep Dive
What Kind of Fitness Tracker is This?
The Whoop Band is a wrist-worn tracker designed primarily for athletes and fitness enthusiasts. Its main focus is on recovery, strain, and sleep, using heart rate variability (HRV) to determine how hard you should push your body each day.
Sleep Tracking Features
- Tracks sleep stages (REM, Deep, Light)
- Monitors sleep disturbances (how often you wake up)
- Provides a Sleep Debt score (how much sleep you’ve lost over time)
- Measures HRV and respiratory rate
- Gives a recovery score based on sleep quality and other metrics
Subscription Model
One major downside is that Whoop requires a monthly subscription. You’ll need to pay $30/month or commit to an annual plan to use the device. While this is a dealbreaker for some, the in-depth analytics may be worth it if you’re serious about tracking performance.
Pros & Cons
✅ Advanced sleep & recovery tracking ✅ No screen, fully app-based ✅ Comfortable & lightweight ✅ Ideal for athletes ❌ Subscription required ❌ Less focus on overall wellness ❌ No step counting (if you want daily activity tracking)
Who Should Get This?
If you’re an athlete or someone looking to optimize recovery and training, Whoop is a fantastic option. The sleep tracking is detailed, and its ability to measure strain and readiness makes it great for those pushing their physical limits.

What is the Oura Ring?
The Oura Ring is a sleek, discreet wearable that fits on your finger and tracks sleep, readiness, and activity. Unlike the Whoop Band, it does not require a subscription to access basic tracking features.
Sleep Tracking Features
