Frequently asked questions
What is the smart ring?
It's a ring that tracks your sleep, physical activity, heart rate variability, and more, day and night, turning it all into easy-to-read scores in the app. Continuous, discreet tracking — you'll almost forget you're wearing it.
How do I find the right size?
Measure the circumference of your finger and pick the matching size, or use our sizing guide on the product page.
Which finger should I wear it on?
We recommend the index, middle, or ring finger, preferably on your non-dominant hand. Performance stays consistent on any of them — pick whichever feels most comfortable.
What's included in the box?
The ring, the charging case (which also works as a protective case), the chargers, and the instruction manual.
How do I track my health data?
Everything syncs automatically to the app on your phone — heart rate, sleep, activity, stress, and more, with simple 0–100 scores. Available on the App Store and Google Play.
Which phones are compatible?
Compatible with iOS 9.0+ and Android 5.0+.

FAQ
Use this text to share information about your product or shipping policies.
Is there really no subscription?
None. You buy the ring once and your full health dashboard — sleep, HRV, recovery score, everything — is yours forever. No monthly fees, no paywalled features.
How do I know which size to order?
We recommend ordering a free sizing kit before purchasing. It ships at no cost and includes plastic sizers for every size from 7 to 13. Select "Free Sizing Kit" at checkout.
Can I wear it in the shower, ocean, or pool?
Yes. Vyne Ring is water resistant to 50 meters (5ATM). Shower, swim, surf — it handles all of it without issue.
How accurate is the sleep tracking?
The finger is one of the best locations for optical heart rate sensing — more accurate than the wrist. Vyne's sleep algorithm uses PPG + accelerometer data to detect sleep stages with clinical-grade precision.
How long does shipping take?
Orders placed before 12:00pm ship the same day and typically arrive within 3–7 business days depending on your location. Express options available at checkout.
Is it compatible with my phone?
Yes. The free Vyne app is available for both iOS (iPhone 8+) and Android (8.0+). Syncs via Bluetooth 5.0.
