Frequently Asked Questions
Everything you need to know about screenless wearables, smart rings, and quiet health tracking devices.
General
What are screenless wearables?
Screenless wearables are health monitoring devices that track your fitness and wellness metrics without a display. They include smart rings, screenless bands like WHOOP, and under-mattress sleep monitors. These devices focus on passive data collection without notifications or distractions.
Do screenless wearables work without a phone?
Screenless wearables collect data independently but require a smartphone to sync, view insights, and configure settings. The wearable stores several days of data locally, so you don't need your phone nearby 24/7.
Are smart rings as accurate as smartwatches?
For sleep tracking and resting heart rate, smart rings can be more accurate than wrist-worn devices due to better blood flow in fingers. However, for workout tracking and real-time heart rate during exercise, wrist-worn devices may perform better.
Smart Rings
How long do smart ring batteries last?
Most smart rings last 4-8 days on a single charge. Oura Ring Gen 4 lasts up to 8 days, Samsung Galaxy Ring lasts 7 days, and Ultrahuman Ring Air lasts 4-6 days depending on usage.
Can I wear a smart ring while showering or swimming?
Yes, all major smart rings are waterproof. Oura Ring, Samsung Galaxy Ring, and others have 10 ATM (100m) water resistance, making them safe for swimming, showering, and water sports.
What size smart ring should I get?
Always order a free sizing kit before purchasing. Ring size can vary between brands. Most companies offer sizes 6-13 in US sizing. Wear the sizing ring on your intended finger for 24 hours to ensure comfort.
Do smart rings require subscriptions?
It depends. Oura Ring requires $5.99/month after the first month. Samsung Galaxy Ring, RingConn, and Ultrahuman Ring Air have no subscription fees. WHOOP requires a membership starting at $30/month.
Health & Accuracy
Are screenless wearables FDA approved?
Most consumer fitness wearables are not FDA-approved medical devices. They're wellness devices for general health monitoring. Some features like ECG or AFib detection may have FDA clearance, but always consult a doctor for medical decisions.
Can screenless wearables detect sleep apnea?
Some devices can detect signs of sleep apnea through SpO2 and breathing pattern monitoring. Withings Sleep Analyzer and Oura Ring can flag potential sleep apnea risks, but you need a medical sleep study for diagnosis.
How accurate is HRV tracking on wearables?
HRV accuracy varies by device. Oura Ring and WHOOP show strong correlation with medical-grade equipment. For best results, track trends over time rather than focusing on individual readings.
Buying & Setup
Where can I buy screenless wearables?
You can purchase from Amazon (which we recommend for easy returns and Prime shipping), directly from manufacturer websites, or retailers like Best Buy. We include Amazon affiliate links to help support our reviews.
Can I return a smart ring if it doesn't fit?
Yes, most manufacturers and Amazon offer 30-day return policies. Some brands like Oura offer a 30-day trial period. Always check the specific return policy before purchasing.
Do screenless wearables work with both iPhone and Android?
Most do, with exceptions. Samsung Galaxy Ring only works with Android. Oura Ring, WHOOP, Ultrahuman, and most others support both iOS and Android.
Privacy & Data
Are my health data private and secure?
Reputable brands like Oura, Samsung, and Withings use encryption and comply with privacy regulations like GDPR and HIPAA. Always review each company's privacy policy. Your health data is never sold without consent.
Can I export my data from a screenless wearable?
Most devices allow data export through their apps or API integrations with Apple Health, Google Fit, or other platforms. This ensures you're not locked into one ecosystem.
