Secofy Smart Fitness and Activity Ring: No subscription fees
This smart ring is for anyone who wants to track their health without wearing a bulky watch. It fits easily on your finger and works all day and night.
Unlike glossy trackers that show every fingerprint, this ring has a frosted finish with polished edges. It resists smudges and grease, so it always looks clean. The subtle shine on the edges adds a touch of style.
Sleep tracking is automatic. The ring detects deep, light, and interrupted sleep stages. You get daily, weekly, and monthly reports to help you improve your rest. During the day, it tracks your heart rate and HRV every 5 minutes without you tapping anything. For blood pressure, SpO2, and stress, just open the app for an on-demand reading. It also supports women's cycle tracking with notifications for periods and fertile windows.
Battery life lasts 3–5 days on a single 1.5-hour charge. The charging case gives you over 15 days total, perfect for trips. The ring is waterproof to 50 meters, so you can swim or shower with it. And there are no subscription fees – all features are free.
