Huami has unveiled two new GPS fitness tracker models: GTR 3, and GTR 3 Pro, equipped with round screens, are protected from water, but the 5ATM marking indicates that, although you can swim with them in the pool, it is undesirable to dive with them.
Amazfit GTR 3 Pro is made of aircraft-grade aluminum and weighs only 32 grams. The fitness GPS tracker is available in two versions: Brown Leather (light gray case and brown strap) and Infinite Black (dark gray case and black fluoroelastomer strap). The GTR 3 also has two color options: Thunder Black and Moonlight Gray (light gray).
GTR 3 Pro smart watch for Android received a 1.45-inch AMOLED screen with a pixel density of 331 per inch and a peak brightness of 1000 cd / m2, as well as an increase (compared to the previous generation model) frame rate by 67%. The screen occupies 70.6% of the front panel area of the Amazfit GTR 3 Pro. The Amazfit GTR 3 has a slightly smaller screen – its diameter is 1.39 inches. The pixel density corresponds to the older model, but the ratio of the screen area to the front panel is slightly less – the display accounts for 66%.
Amazfit GTR 3 Pro has more than 150 themes (GTR 3 has more than 100) and Always On mode. 15 themes – animated, and some can even be edited – choose which widgets will be displayed on the screen. More than 150 training modes are also supported.
Together with the watch, Amazfit presented a new software platform on which it is built. It is called Zepp OS and has a very simple interface. Zepp OS doesn’t have as many features as Google Wear OS, but the platform does support third-party apps. Moreover, the company has prepared a set of tools for the development of themes and even applications based on a web engine, so that almost anyone, armed with proprietary instructions, can create something of their own for the watch, and then share this creation with other users. The Amazfit watches work with the voice assistant Amazon Alexa (and this does not require a network connection), is compatible with Apple Health and Google Fit, as well as several popular applications – Strava, Relive, RunKeeper, etc.
A special feature of the new Amazfit watches is a new six-channel optical sensor BioTracker PPG of the third generation, working together with the second generation RealBeats algorithm. Amazfit GTR 3 Pro and GTR 3 monitor heart rate and blood oxygenation 24/7. The developers focus on the fact that it takes only 15 seconds to determine SpO2 – almost half the time required for a second-generation watch. There’s also a sleep monitoring system that can even track your breathing rate.
Both GPS fitness tracker models are equipped with GPS receivers, with the Pro version supporting five systems: GPS, Galileo, GLONASS, Beidou, and QZSS. Due to this, the positioning accuracy has increased by 40%.
The Amazfit GTR 3 Pro has a microphone and a built-in loudspeaker, which allows you to answer calls directly without a smartphone. The internal memory of the device provides 2.3 GB for storing music. It is not the case in GTR 3.
The maximum battery of the Amazfit GTR 3 Pro is 12 days. Or 35 hours using GPS. Power saving mode Battery Saver Mode allows you to extend the juice up to a month. The battery of Amazfit GTR 3 is much more – up to 21 days (10 days with intensive use).
