Don't guess your sleep. Get data that helps you wake up refreshed. The RENPHO LYNX Smart Ring is for anyone who wants to understand their nighttime recovery and daily activity without wearing a bulky watch or paying a monthly fee. Track your sleep stages, heart rate, blood oxygen, and stress levels automatically, and see a Health Index score each morning.

Use the free Renpho Health App—no subscription needed. Sync with Apple Health or Google Health Connect. The ring runs 7–12 days on a charge, and the included charging case adds another week, so it's ready when you travel. It's 5ATM waterproof, so you can swim or wash hands without removing it. The titanium exterior is tough enough for 24/7 wear.

Before ordering, use the official RENPHO sizing kit to get the right fit. Sizing differs from standard rings. Wear the ring with the sensor facing your palm for accurate readings. Remove it before applying lotion to prevent slipping.
