Polar H7
Score: 74/100
Fitbit Sense 2
Score: 83/100Rankings
The Fitbit Sense 2 is a premium health-focused smartwatch offering comprehensive sensors like ECG, skin temperature, and SpO₂ alongside built-in GPS and up to six days of battery life. Its heavier weight and lack of Wi-Fi connectivity limit its appeal for users seeking a lighter, more standalone device. Ideal for health-conscious athletes who value deep analytics.
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 highlight the Sense's advanced health toolkit-cEDA stress monitoring, skin temperature tracking, and SpO₂ measurement as innovative steps beyond typical fitness trackers, while noting the limited regional availability of the ECG feature.
