Amazfit Band 7
Score: 80/100Rankings
The Amazfit Band 7 is a budget-friendly fitness band featuring a 1.47-inch AMOLED screen, up to 18 days of battery life, and 120 sport modes with Alexa integration. It lacks built-in GPS and can suffer from app sync issues. It targets casual fitness enthusiasts who value long battery and a vibrant display.
The Polar H7 is a chest-strap heart-rate sensor delivering ECG-grade accuracy and a long-lasting CR2025 battery. It lacks ANT+ support and cannot transmit data while swimming, and its older design may feel bulkier. Best suited for athletes who need precise chest-based heart-rate data and long battery life.

Professional reviewers commend the H7 for its ECG-grade accuracy, long-lasting battery, and lightweight belt design, noting its seamless Bluetooth and GymLink integration for a wide range of devices. However, they point out its legacy status, lack of ANT+ and inability to transmit data underwater, making it less future-proof than newer Polar models.
Everyday users appreciate the H7's reliable Bluetooth pairing, comfortable elastic strap, and long battery life, especially for running, gym, and swimming workouts. Recurring complaints focus on occasional pairing hiccups with non-Polar phones, strap stretch over time, and the desire for a lighter, wrist-based alternative.
Professional reviewers view the Amazfit Band 7 as a strong budget option, lauding its long battery life, bright AMOLED display and generous feature set including Alexa and 120 sport modes. They note the trade-offs of missing GPS, limited advanced health sensors and occasional app sync issues, positioning it as a value-focused alternative to pricier smart bands.
Everyday users praise the Band 7 for its impressive battery endurance, vibrant screen and comfortable all-day wear, especially appreciating its water resistance for swimming. Common complaints revolve around app stability, occasional heart-rate inaccuracies, the band's length on smaller wrists, and the lack of independent GPS for outdoor activities.
