Latest Update Brings New Features to Amazfit Active Max
The Amazfit Active Max smartwatch is now getting a fresh update of its software, version 3.7.0.1. This device was last updated earlier this year, in March 2026, with version 3.4.0.3. That update brought a dedicated Podcast app plus new activities like Rucking and Hybrid Training, making the device more versatile. Now, the manufacturer focuses on enhanced health tracking.
Lactate Threshold Measurement Adds Value
Amazfit’s latest update introduces a new Lactate Threshold feature. This tech allows users to better understand how their stamina performs during workouts, and fine-tune training routines. You can manually run this test by navigating through the menu: Workouts > Choose Running > Settings > Training > Lactate Threshold Test. Or, just let the watch do it automatically, then see the data in the Zepp app. Other models like the T-Rex 3 Pro, Balance 2, and Active 3 Premium already support this feature, showing its growing importance.
Enhanced Sleep Monitoring Technology
An additional significant update is improved accuracy in sleep tracking. The latest software optimizes how the watch detects sleep stages, trying to be more precise in categorizing Light, Deep, and REM sleep. Besides this, Amazfit mentions that there are other minor system tweaks and bug fixes, though details are not provided. The goal is to give users better insights into their sleep quality with less errors.
Availability and How to Update
The rollout of software version 3.7.0.1 is happening gradually to users of the Amazfit Active Max, which is now priced around $169.99. The update should become available to your device in the coming days or weeks, depending on your region. When it does, you can start the installation through the Zepp app on your smartphone, ensuring your smartwatch stays current with the newest features and corrections.
