Score: 87/100
Fitvii Fitness Tracker
Score: 82/100Rankings

The Suunto Smart Heart Rate Belt is a chest-strap monitor offering ECG-grade accuracy and an industry-leading 500-hour battery life. Its main trade-offs are a short 3-meter transmission range and the lack of an on-strap display. Best suited for multisport athletes who already use Suunto devices.

Fitvii FITVII Health & Fitness Tracker is a budget-friendly smartwatch offering 24/7 heart rate, blood pressure, SpO₂ monitoring and 120+ sport modes, with up to 7-day battery life and Bluetooth calling. Its limitations include lack of SMS reply capability, a finicky magnetic charger, and water-resistance that doesn't cover hot baths or deep diving. Best suited for beginners and casual fitness enthusiasts seeking a feature-rich, affordable wearable.
