Amazfit GTR 4

Inaccurate GPS tracking in built-up areas and daily charging are typical weaknesses of many smartwatches in the lower price segment. The Amazfit GTR 4 addresses this issue with innovative GPS antenna technology and a resource-efficient operating system. Users receive a durable fitness tracker in the guise of a classic wristwatch.

Classification and Target Audience

In the wearable market, the model is positioned in the mid-price range. Expert articles and reviews confirm its focus on budget-conscious everyday users and hobby athletes who prioritize accurate route tracking and long battery life without wanting to spend on premium manufacturers.

Individuals who must pay with the watch at checkout, are deeply integrated into the app worlds of Google or Apple, or require flawless heart rate data during high-intensity intervals as professional athletes are explicitly not part of the target audience.

Technical Features and Advantages

The technical foundation consists of a 1.43-inch AMOLED display encased in a lightweight aluminum alloy frame. A significant technical advantage, praised across reviews in various industries, is the dual-band GPS with a circularly polarized antenna. This technology ensures exceptionally precise route tracking, which according to aggregated tests reaches the level of much more expensive premium sports watches even in dense forests or high-rise canyons.

The optical BioTracker 4.0 sensor on the back continuously measures heart rate, blood oxygen (SpO2), and stress levels. An integrated speaker and microphone enable phone calls via a Bluetooth connection to a smartphone. Additionally, the watch offers internal storage for local music files. Battery life is consistently confirmed in independent measurements at moderate everyday use, ranging from 10 to 14 days.

Weaknesses and Compromises

The biggest functional drawback in everyday use is the complete absence of an NFC chip in the global standard version. Contactless payments at the supermarket checkout are thus hardware-wise excluded with the Amazfit GTR 4.

Moreover, the proprietary Zepp OS operating system reveals weaknesses in app selection. While there is an integrated store for mini-apps, established third-party applications like Spotify, WhatsApp (as a native app), or Google Maps are completely missing. Another compromise measured in tests concerns the heart rate sensor: In sports with abrupt and rapid heart rate changes, such as weight training or high-intensity interval training (HIIT), the optical measurement often reacts delayed and inaccurately compared to a chest strap.

Conclusion & Purchase Recommendation

The price-performance ratio is objectively excellent at a market price often well below 200 euros. Those looking to buy the Amazfit GTR 4 will receive an aesthetically pleasing smartwatch with outstanding GPS accuracy and strong battery life. Anyone seeking a durable fitness watch recommendation for a limited budget and can forgo payment functions will find an extremely reliable training tool here. However, those who absolutely need NFC must turn to the newer sister model Amazfit Balance or competitive models from Samsung and Garmin.
