The reviewer found one of the fitness trackers "genuinely shocking" and "terrible," but did not explicitly name it in this excerpt, though his strongest criticisms were directed at the Hume Band's app experience, battery life, and charging design. He was generally impressed by the Amazfit Helio Strap for its price and flexible app model, and noted the Polar Loop's hardware was great despite its dated app.
This video reviews and tests four fitness trackers: the Amazfit Helio Strap, Polar Loop, Hume Band, and Whoop 5.0. The reviewer compares their physical characteristics, battery life, app experiences, and core health tracking features. The ultimate goal is to determine their accuracy, although the detailed accuracy tests are not included in this transcript excerpt.
The Amazfit Helio Strap is a highly recommended budget fitness tracker, offering impressive battery life and robust features for its cost. The device's tiny form factor (33.8 x 24.2 x 11 mm) ensures comfort, and its 10-day battery life significantly outperforms many premium devices. While the Zepp app initially required adjustment, frequent updates have improved its functionality, providing a useful PAI score and customizable metrics. If you prioritize long-lasting battery power and value for money, this device is an excellent choice, though you may want to consider a bicep band for enhanced accuracy.

The Zepp app, initially disliked, has grown on the reviewer due to frequent updates. It offers customizable core metrics, calorie tracking, live heart rate, step count, stress tracking, and a 'pie score' for gamified exertion tracking, along with comprehensive sleep and activity reports.

The device offers an optional subscription called Aura, but all core features remain available without it for a one-time fee. Users can also hide the Aura tab, which the reviewer finds commendable compared to competitors.

The reviewer states that the Polar Loop app feels dated and is not as modern as others. It displays data chronologically and its sleep graph is not intuitive.

Polar uses an 'ANS charge' recovery score from -10 to +10, calculated by heart rate, HRV, and breathing rate during the first 4 hours of sleep to indicate recovery needs.

The Hume Band's brain is 41.9 mm by 22.7 mm and 13.6 mm thick, making it thicker than others. The reviewer notes a side button whose function is unknown to him.

The Hume Band has the worst battery life in the video, lasting only 4 to 5 days. Its charging experience involves a bulky, awkward box and a flimsy cable, despite a quick 80-minute charge time.

The Hume Band app's main issue is a permanent upsell for a premium version on the homepage, which the reviewer finds frustrating. The health score variables are unclear, and the 'metabolic' terminology feels like an attempt to create allure rather than clear data.

The Hume Band app is missing many sleep tracking features. While it shows sleep duration and a graph of sleep stages, it doesn't display time spent in each stage, sleep consistency, or exact fall asleep/wake up times, which are crucial for understanding circadian rhythm.

The Amazfit Helio Strap is notably small, measuring 33.8 mm x 24.2 mm x 11 mm. It boasts a strong water resistance of 500 meters for 10 minutes and an excellent battery life of up to 10 days on a single charge, recharging fully in 2 hours via a magnetic charger. The reviewer suggests buying a bicep band for it.
The Zepp app, though initially not a favorite, has improved with frequent updates, offering customizable metrics, detailed tracking for activity and sleep, and a 'pie score' for exertion. Crucially, while there's an optional 'Aura' subscription, all core features are available with a one-time fee, and the subscription tab can be hidden, offering a consumer-friendly experience.
The Polar Loop is characterized by its thin design, measuring 42.4 mm x 26.6 mm x 9 mm, and comes with two band sizes for better fit. It offers water resistance up to 30 meters, suitable for daily activities like showering. Its battery lasts up to 8 days, which is decent but shorter than the Amazfit Helio Strap.
The reviewer found the Polar Loop's app to be dated and not as modern as other fitness tracker apps, with a less intuitive sleep graph. Despite this, it offers detailed sleep stage tracking, chronological data for workouts, and a unique 'ANS charge' recovery score that uses heart rate, HRV, and breathing rate to assess recovery needs.
The Hume Band measures 41.9 mm x 22.7 mm x 13.6 mm, making it thicker than the other trackers. While it's water-resistant to IP68 (1m for 2 hours), its battery life is the shortest, lasting only 4 to 5 days. The charging experience is also criticized for its bulky, awkward box and flimsy cable, despite charging fully in 80 minutes.
The Hume Band's app prominently displays a permanent upsell for its premium version on the homepage, which the reviewer finds frustrating given the device's price. The health, metabolic momentum, and metabolic capacity scores are presented without clear explanations of their underlying variables, making them difficult to understand. The reviewer believes the extensive 'metabolic' branding creates an allure rather than providing clear, actionable insights.
While the Hume Band can track sleep duration and show a graph of sleep stages, it fails to display critical details such as the time spent in each sleep stage (deep, REM, awake). It also lacks information on sleep consistency, fall asleep times, and wake-up times, which are vital for users trying to establish a healthy circadian rhythm.
