Frequently Asked Questions
Are smart rings accurate for fitness tracking?
Smart rings offer good accuracy for most health metrics. Sleep tracking tends to be their strongest feature, often matching or exceeding the accuracy of wrist-worn devices. Heart rate monitoring is generally reliable during rest and light activity but may struggle during high-intensity workouts. Step counting accuracy varies between models but is typically sufficient for tracking general activity trends.
Do I need a subscription for smart rings?
Some smart rings require subscriptions while others do not. Oura Ring requires a monthly fee ($5.99/month) to access most features. Samsung Galaxy Ring, RingConn, Ultrahuman Ring Air, and Amazfit Helio Ring offer their core features without subscriptions. Always check subscription requirements before purchasing to avoid unexpected costs.
How long do smart ring batteries last?
Battery life ranges from 3-12 days depending on the model and features used. The RingConn Gen 2 offers the longest battery life at 10-12 days. Most other rings average 5-7 days between charges. Battery performance decreases when using continuous monitoring features or tracking workouts frequently.
Can smart rings track blood pressure?
Some smart rings claim to measure blood pressure, but these readings should be considered estimates rather than medical-grade measurements. Rings like the Milavan and FitElf 3 Pro include blood pressure monitoring, but users should verify important readings with validated medical devices. These features are best used for tracking relative changes rather than absolute values.
Are smart rings waterproof?
Most smart rings in 2026 offer water resistance sufficient for showering, handwashing, and swimming. Look for IP68 ratings or specific water depth ratings (like 10ATM for the Samsung Galaxy Ring). Avoid exposing smart rings to hot water, steam, or saltwater, as these can damage sensors and electronics despite water resistance claims.
Which smart ring is best for sleep tracking?
The Oura Ring 4 consistently ranks highest for sleep tracking accuracy and detailed sleep stage analysis. The Ultrahuman Ring Air and RingConn Gen 2 also provide excellent sleep insights. The RingConn Gen 2 stands out for its unique sleep apnea monitoring capabilities not found in most competitors.
Can smart rings track specific workouts?
Most smart rings offer basic workout tracking with some automatic activity detection. They typically track duration, heart rate, and estimated calorie burn. Some rings like the Samsung Galaxy Ring and Oura Ring 4 can automatically detect common activities like walking, running, and cycling. For serious athletes, smart rings work best as supplements to dedicated fitness devices rather than replacements.
How do I find my correct smart ring size?
Most manufacturers recommend ordering a sizing kit before purchasing a smart ring. These kits contain plastic ring sizers that match the exact dimensions of the actual smart rings. Wear the sizing ring for 24 hours to ensure comfort throughout daily activities, temperature changes, and sleep. A proper fit should be snug but comfortable, as loose rings produce less accurate readings.
