Fitvii Slim Fitness Tracker
Score: 74/100Rankings

The FITVII Slim is a budget-friendly fitness tracker that adds blood pressure monitoring, SpO₂ and music control to a waterproof metal design. Its limitations include a low-resolution LCD screen and lack of GPS, which may deter more serious athletes. Suited for casual users who want comprehensive health metrics without a high price tag.

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.
