TOMTOP JMS Smart Ring: Tracks movement up to 164 feet
This smart ring is for the active professional who wants health insights without a bulky wearable. While many focus on fitness tracking, it excels as a discreet wellness companion, giving you a clear picture of your daily readiness and recovery.

You get subscription-free access to your data, which syncs with Apple Health and Google Fit. Its lightweight titanium alloy design is comfortable for all-day wear, and the IP68 waterproof rating means it handles workouts and daily life with ease.
