At SLEEPON, we have always believed that better sleep starts with accurate insights.
Now, our belief is backed by science: the Nature Scientific Reports journal — one of the world’s most respected peer-reviewed publications — has featured a clinical study comparing leading smart sleep rings, including our very own Go2Sleep.

This independent, peer-reviewed research confirms what our users already know: Go2Sleep is a reliable, clinically relevant, and cost-effective tool to monitor your sleep health.

Trusted by Science: Key Findings from the Study

The study, titled “Performance of wearable finger ring trackers for diagnostic sleep measurement in the clinical context”, evaluated three popular sleep tracking rings (Oura, Go2Sleep, and Circul) against the clinical gold standard — polysomnography (PSG).

Here’s what the researchers found about Go2Sleep:

• ✅ Accurate Sleep/Wake Detection – Go2Sleep reached ~85% accuracy in distinguishing sleep from wake, nearly matching the best-performing device in the study.
• ✅ Reliable REM Tracking – Go2Sleep showed the smallest average error in REM sleep duration (+2.7 minutes compared to PSG), giving users more confidence in monitoring this critical stage for memory and recovery.
• ✅ Consistent Performance Across Patients – Despite including participants with real clinical sleep disorders (sleep apnea, insomnia, etc.), Go2Sleep maintained strong detection performance, proving its suitability for real-world users.
• ✅ Comfortable to Wear – Participants reported that Go2Sleep was comfortable enough for all-night monitoring, a crucial factor for long-term sleep tracking.

📊 Key Data Snapshot (Go2Sleep vs. Gold Standard PSG):
• Sleep/Wake Accuracy: ~85%
• REM Sleep Mean Difference: +2.7 min (most accurate among tested devices)
• Total Sleep Time: Slightly overestimated (+50 min on average), meaning users receive optimistic feedback about their sleep quality — great for motivating better habits.

Why This Matters to You

When choosing a sleep tracker, you want a device that is:

• Scientifically Validated – Published research shows Go2Sleep performs on par with the most expensive sleep rings.
• Affordable & Accessible – Go2Sleep delivers medical-grade insights at a fraction of the price of competitors like Oura.
• Focused on Sleep Health – Continuous blood oxygen monitoring, heart rate tracking, and ODI (oxygen desaturation index) detection make it a powerful companion for identifying sleep apnea risks and other breathing issues.

High Performance, High Value

While other premium rings can cost over $300, Go2Sleep offers comparable accuracy and advanced features — for less than half the price.
This means you get science-backed reliability and best-in-class value, without compromising your budget.

Perfect for Trend Tracking and Daily Use

Even the Nature study concludes that rings like Go2Sleep are excellent for tracking long-term sleep trends, monitoring progress, and supporting better sleep habits — exactly what most users need for lifestyle improvement.

Final Word

We’re proud that Go2Sleep has been independently validated by one of the world’s most respected scientific journals. This recognition reinforces our mission: making advanced sleep health monitoring affordable and accessible for everyone.
