Criticisms & Common Complaints

Despite its many advantages, the Amazfit GTR Series has drawn some criticism from the Reddit community. A frequent issue is the GPS accuracy, which some users find inconsistent when compared to brands like Garmin or Apple. For example, a user pointed out that the GPS track was slightly distorted compared to their friend’s Garmin, especially in environments like cities with tall buildings or dense forests. While this may not pose an issue for casual users, it can be an inconvenience for athletes who require precise location tracking. Moreover, some users have reported improvements in GPS accuracy following firmware updates, but it seems it still cannot rival dedicated sports watches.

Another notable criticism is the limited support for third-party applications. Running on Zepp OS, the Amazfit GTR Series does not natively support widely-used apps like Strava or Spotify, prompting users to look for alternative solutions or third-party integration tools. This lack of direct support might deter users seeking a smartwatch with a more extensive app ecosystem.

Additionally, concerns about inconsistent heart rate and SpO2 measurements have surfaced. While satisfactory for general use, these measurements might not suffice for those in need of highly precise health metrics for medical reasons. A user shared that the readings from their GTR 3 were often a few BPMs off when compared to a more accurate chest strap monitor. This reflects the optical heart rate sensor's limitations, falling short of specialized fitness trackers that utilize advanced sensor technology.

  (Source)  

Users generally agree that the Amazfit GTR series looks and feels high-end, often comparable to more expensive smartwatches.  

---

📡 Software and App Experience: Needs Improvement  

While hardware is widely appreciated, Zepp OS and the Amazfit companion app draw mixed feedback. Some users find it functional but limited, while others express frustration over bugs and slow updates.
