This kit includes ring sizers ranging from sizes 6 to 12, allowing you to accurately determine your ring size.

Can I change the color of the ring after making the payment?

Once you choose the color of your Luna Ring & complete your purchase, you cannot change it at a later time.

How does the Luna ring measure my body vitals?

The Luna ring uses PPG sensors by Philips to measure vital signs. These sensors emit light onto your skin, measuring changes in light absorption caused by blood flow.  Luna's advanced PPG sensors empower informed decisions about your health.

Specifically, the Luna ring measures three important body signals: heart rate (HR), oxygen saturation levels (SPO2), and heart rate variability (HRV) for insights into your overall health. Sensors on the inner ring surface contact your skin, accurately capturing data sent to the mobile app for tracking and analysis.

How does the ring estimate how many calories I've burned?

The Luna ring estimates calorie burn by combining data from a motion sensor and heart rate monitor. The motion sensor tracks your daily movement, including steps, distance, and exercise intensity. Heart rate monitor measures how hard your body works during activities, using established algorithms to calculate calories burned. While it provides a good estimate, it may not be 100% accurate for everyone. Individual factors like metabolism and body composition affect accuracy.

What sensors does the Luna ring have?

The Luna ring features three key sensors for tracking. The PPG sensor measures heart rate and blood flow for heart rate variability, offering insights into various health metrics. The temperature sensor monitors skin temperature to track activity changes, aiding in energy expenditure and overall health tracking. The accelerometer detects motion, measuring daily physical activity for calculating calorie burn and activity levels.

What is the battery life of the ring?

The Luna ring has up to 7 day battery life, allowing uninterrupted health vitals tracking. Charging is quick and easy with the included cable. Actual battery life may vary based on usage and settings, but even with regular use, it offers several days of operation before needing a recharge.

How long does it take to charge the ring?

Charging the Luna ring is quick and convenient, taking only 2 hours (120 minutes) for a full charge. Simply connect the charging cable to the ring and plug it into a USB port or wall adapter. Its advanced charging technology ensures a fast and efficient experience. Once charged, the Luna ring can last up to 7 days, depending on usage. This means uninterrupted use and no constant recharging for your vitals tracking.

Which devices is the ring compatible with?

The Luna ring is compatible with both Android and iOS phones. To connect, download the Luna Ring app from the Google Play Store or Apple App Store and follow setup instructions. Track your health data, set goals, and receive personalized insights on your phone with ease.

What colors does the ring come in?

As of now, the Luna ring offers a range of five versatile colors to choose from: Stardust Silver, Midnight Black, Lunar Black, Sunlit Gold and Rose Gold suitable for any occasion. For example, if you prefer a sleek and modern look, the Stardust Silver or Rose Gold with its metallic shine gives a contemporary edge that makes it suitable for both casual and formal settings.

Will there be any allergic reactions / Is wearing the ring long-term damaging to the skin?

The Luna ring, made from hypoallergenic medical-grade titanium, is unlikely to cause allergic reactions or skin irritations. However, consult a dermatologist if you have metal sensitivities. It's lightweight and comfortable, safe for long-term wear. Nonetheless, if you experience irritation or discomfort, take a break from wearing it. Regular cleaning and maintenance would ensure its longevity and optimal condition.

Which finger do I wear the ring on?

The Luna ring is ideally worn on your index finger for optimal tracking. It's the most convenient and comfortable choice for daily activities. However, if you prefer, you can wear it on your middle or ring fingers. Ensure it fits snugly but not too tight, allowing comfortable wear without restricting blood flow. Use our sizing guide if you're unsure about your size. Wearing the Luna ring accurately tracks your vitals for daily convenience. Follow the provided instructions for accurate tracking and maximum benefits.

Ensure that the ridge on the ring is facing upwards to align sensors to the bottom of your finger. 

Can the Luna ring be worn on tattooed fingers?

Wearing the Luna ring on tattooed fingers is possible, but not recommended. Tattoos can interfere with the sensors, affecting accuracy. Tattoo ink may create a barrier, reducing readings' precision. Tattoos can also alter skin texture, potentially affecting ring fit and comfort. Proper fit is crucial for accurate readings.

What is the accuracy of the metrics derived from the ring?

The Luna ring utilizes advanced sensors and technology to accurately track and analyze your metrics, providing real-time data. Rigorous testing, calibration, and algorithm updates against industry standards ensure reliability and precision. While individual variations exist, Luna is known for high accuracy in vital tracking. For concerns or information, our customer support team is available to assist you.

What is the name of the App for the ring?
The name of the app is "Luna Ring". It is available for iOS and Android and offers a seamless experience. Easily connect your Luna ring via Bluetooth to sync data, track various health metrics, and access features. It provides personalized insights and recommendations, empowering informed health and fitness decisions with its user-friendly interface and comprehensive features.

How does the ring sync data through Bluetooth?

The Luna ring uses Bluetooth technology to sync data with your smartphone. Install the Luna Ring app, activate Bluetooth on both devices, and pair them.
