Full review
Longer notes from the same comments we summarized above.
What people reported
Owners are highly impressed with the battery life of the Aura Smart Strap (also known as Helio Strap), with one user reporting 34 days on a single charge. The strap also delivers accurate step counting, often matching Apple Watch and Garmin devices. For health monitoring, users found live heart rate, HRV (Heart Rate Variability), and sleep apnea risk tracking to be accurate. The associated Zepp app is reported to be glitch-free. Many appreciate its waterproof nature, making it suitable for pool sessions.
Problems people mention
A notable issue for gym users is the lack of a bicep strap, which one owner considered the "biggest overlook" and had to purchase aftermarket. Users found that workout detection sensitivity needs to be set to "low" to prevent inaccurate and ridiculously high calorie burn readings. The automatic workout detection is also limited to basic strength training workouts. One user noted that SpO2 tracking sometimes generated very low values randomly, raising concerns. Another user had an initial inaccurate sleep tracking experience, logging 11 hours for 7.5 hours of actual sleep, although this was a single instance. The "stress" indicator was also considered "flawed" by one owner.
Where owners disagree
While one user initially found sleep tracking inaccurate in a single test, another enthusiastically rated it 10/10 for accuracy, even detecting lucid dreaming. This suggests that initial calibration or specific usage patterns might influence early experiences.
Who it's for
The Aura Smart Strap (Helio Strap) is well-suited for active individuals looking for a dedicated fitness and health tracker without the bulk of a smartwatch. It particularly appeals to those who prioritize long battery life, accurate core tracking (steps, heart rate, sleep), and water resistance for swimming. Users who engage in gym workouts should be prepared to invest in an additional bicep strap.
