Editor's Pick: Wear it to sleep to track your sleep cycles, and it automatically records your walking and running data during the day. The charging case is portable—just place the ring inside for a full week of battery life, so you don't need an extra charging cable when traveling. The casing is titanium alloy with a 5ATM water resistance rating, so you can wear it while swimming. Use the Renpho Health app to view your data with no additional subscription fee.
