Polar H7
Score: 74/100
Fitbit Inspire 3
Score: 77/100Rankings
The Fitbit Inspire 3 is a slim, lightweight fitness tracker that excels with a 120-hour battery and built-in GPS. Its trade-off is a tiny screen and lack of advanced smartwatch features. Best for users who want basic health monitoring and swimming capability without a bulky device.
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.
