The Amazfit Cheetah 2 Ultra is receiving a free software update to firmware version 6.1.206.1. The update is approximately 19.72 megabytes in size and introduces exciting new features, especially for runners: Grade-Adjusted Pace, a map download manager, improved offline route planning, and tighter integration with Apple Health. According to a changelog shared on Reddit, the update has already arrived in Germany.
Key Points at a Glance
- Firmware 6.1.206.1, approximately 19.72 MB, free and rolling out gradually
- New: Grade-Adjusted Pace for comparable pace values on inclines
- Map downloads can now be paused and prioritized
- Apple Health now also receives heart rate variability (HRV) data
- Plus, more accurate elevation data and navigation improvements
What does this update bring to the Amazfit Cheetah 2 Ultra?
The biggest practical improvement concerns the maps. Previously, downloads simply ran their course; now, you can manage them. Specifically, this means you can pause a download in progress and prioritize another one. It sounds trivial, but it’s really useful in everyday life. If you only need the small map section for today’s hike at first and then want to load a larger region later, you no longer have to wait until the large download is completely finished.
Offline route planning has also been revamped. You can now simply save routes without the navigation starting immediately. This means you can load several routes onto your watch in advance and decide which one to take today once you reach the trailhead. According to the changelog, the update also includes more accurate elevation data, minor navigation improvements, and optimized text for route guidance.
Grade-Adjusted Pace: What’s Behind It?
Grade Adjusted Pace (GAP) approximates your speed on an incline to an equivalent pace on flat ground. The idea behind this is that you slow down when going uphill, even though the effort is the same or greater. A simple minutes-per-kilometer display therefore penalizes you on climbs without reflecting the actual exertion.
This is exactly where GAP comes in. The metric translates your effort on the hill into a pace that you can compare with your flat-terrain runs. For trail running, this isn’t just a nice extra—it’s one of the key metrics for effectively managing your pace across varying terrain. The fact that Amazfit is now adding this feature closes a noticeable gap compared to Garmin and Coros.
Better Apple Health Integration
On the iPhone side, compatibility with Apple Health has been expanded. A new feature is that the watch now also sends heart rate variability data to Apple Health. Users who centralize their health data within Apple’s ecosystem will get a more complete picture and no longer have to switch back and forth between the Zepp app and Health.
This aligns with the direction Amazfit has recently been taking. Just recently, the Cheetah 2 Ultra gained the ability to reply to messages directly on the iPhone. The manufacturer is gradually moving toward a level of integration similar to what’s found on the Apple Watch, while remaining significantly more affordable.
How do I get the update?
The update is being rolled out via the Zepp app. Open the app, select your watch, and check under System Settings to see if an update is available. It’s not yet clear whether firmware version 6.1.206.1 has reached all users; Amazfit typically rolls out updates in stages over several days. The version has already been spotted in Germany, so a little patience may still be required.
