Fitvii Fitness Tracker
Score: 70/100Rankings

The ZURURU Y39 offers a lightweight 25 g design, 5-ATM waterproofing and continuous heart-rate and blood-pressure monitoring, making it a solid budget tracker. Its small 0.96-inch screen and lack of built-in GPS are notable compromises. Best suited for casual users who prioritize affordability, basic health metrics and water resistance over advanced navigation or large displays.

Fitvii FITVII is a feature-rich fitness tracker with a 1.69-inch screen, 7-day battery life, built-in Bluetooth calling, and extensive health monitoring including blood pressure and ECG. Accuracy of its medical-grade measurements is limited and the IP67 rating isn't suitable for swimming. Ideal for health-conscious beginners who value on-wrist calling.

Professional reviewers commend the Fitvii FITVII for its long battery life, clear Bluetooth call quality, and extensive sport mode library, noting the inclusion of advanced health sensors like ECG and non-invasive glucose as innovative for the price segment.
