Amazfit is enhancing its popular Helio Strap with a fresh software update, version 3.0.6.4, aimed at boosting its heart rate features. Released globally in June 2025, this fitness tracker has quickly garnered attention, and this marks the second software update post-launch.
The update, weighing in at 2.24 MB, focuses on improving two essential aspects of heart rate monitoring. First, it optimizes the stability of the heart-rate broadcast feature, allowing smoother connectivity with compatible devices like Garmin smartwatches. Many users have already noted enhancements in heart rate data synchronization.
Additionally, the update offers improved data storage, enabling the device to log heart rate information for up to 21 days continuously. Besides these key improvements, the update also brings minor bug fixes and general enhancements to the device’s performance.
Amazfit typically rolls out updates in stages, so it’s unclear how widely this version is currently available to users. The Helio Strap, available at around $99.99, continues to be a strong contender in the fitness tracker market with these ongoing enhancements.
As Amazfit keeps refining their tech, users can look forward to a better tracking experience and more reliable performance with each update.
