Amazfit GTR 3

Usually, people interested in an all-purpose smartwatch choose a model from the Amazfit GTR line. It is Zepp Health’s more reasonably priced alternative to popular smartwatches like the Apple Watch and the Samsung Galaxy Watch. A timepiece that, in all likelihood, does not garner nearly as much recognition as it ought to.

In October, the company revealed that the GTR 3 would be getting a third-generation, along with a Pro variant and the Amazfit GTS 3. The final product on our list is a square model equipped with almost the same sensors as the GTR 3. The Pro version includes several additional features, such as audio storage and a built-in temperature sensor.

We have been waiting for the following product or service offering from Zepp Health with bated breath. The business announced a few months ago that all of its forthcoming watches would use updated versions of their real-time operating system (RTOS) and brand new sensor technology. These are the very first pieces of hardware to receive these updates.

I’ve been putting the Amazfit GTR 3 through its paces for the past several weeks. During that time, I’ve discovered that it offers numerous advancements over the prior generation in various ways. Please continue reading for a comprehensive breakdown of my thoughts, including the benefits and drawbacks of using the watch and the accompanying app in everyday life.

Review of the Amazfit GTR 3: Design and Hardware - This is One Sharp-looking Wristwatch

  • Touchscreen with an AMOLED display that is bright and colorful
  • One can rotate the crown to navigate the various menus.
  • New Biotracker 3.0 engine
  • Battery life of 21 days while in regular mode

Appearance and Feeling

In terms of the release of new hardware in 2021, Zepp Health has not provided us with a lot of information. Due to the peculiar nature of the year, the business is not truly an exception to the rule. There is more than one contributor to the problem. These include the epidemic caused by the coronavirus, which does not appear to have an end in sight, as well as the chip constraints and the energy crises that are affecting critical Asian countries.

But in reality, this was a remarkable shift in strategy from the years before, when we had a lot of Zepp Health watches – some may even say we had too many of them. The company has been finishing its new operating system and introducing upgrades to its sensor technology while they have had some downtime recently.

New models of the watch have been released every year for the past three years in a row. The Amazfit GTR 3 is an upgrade to the device from the previous year. I had a lot of fun with the first two options, but I discovered that they both had certain drawbacks, such as the fact that the GPS was often unreliable and difficult to connect to. In addition to this, the readings of the heart rate were not always reliable.

In terms of the Amazfit GTR 3, it has preserved most of the qualities that its predecessor had. A smartwatch that gets straight to the point while yet looking good.

Several minor distinctions are essential to point out. To create a genuinely smooth appearance, for instance, the corners have been rounded off quite a little this time around. Additionally, Zepp Health has shrunk the diameter of the body made of aluminum alloy by 0.6 millimeters in order to make it more compact. The thickness has remained pretty much the same at 10.8 millimeters, which is rather excellent.

The watch’s weight is another one of its standout features. It weighs only 32 grams (without the strap), which is significantly less than most of its competitors. The GTR 3 appears to be of the highest quality and feels remarkably light when worn on the wrist.

You’ll see that the two push-button design is still present, but the buttons themselves have given a little more focus. Both may be programmed, allowing you to tailor their capabilities to your specific needs. If you press the top button, you will be sent to the complete list of apps; if you press the bottom button, the screen will take you to the exercise display.

The top button is the subject of a generational leap representing a welcome upgrade over its predecessor. It has taken on the appearance and behavior of a traditional navigation crown, or to be more precise, a scroll wheel. If you want to take a page out of Apple’s book, you can spin the button, and this will cause the options to scroll up and down. The feature works quite well and seems to be a welcome improvement over earlier product editions.

There is a small microphone in the middle of the buttons; you will need to use this to engage with Alexa. However, there is not a person speaking.

Brightness, vibrant colors, and responsiveness to touch are three qualities that stand out on the 1.39-inch AMOLED display with a resolution of 454 by 454 pixels and 326 pixels per inch. In all honesty, this is one of the watch’s most impressive features. An always-on choice is offered for users who desire a screen that does not turn off at any point. If you turn this feature on, however, it will significantly reduce the remaining battery life. I determined that I would not remove it.

You have a wide variety of watch faces to select from, just as you did previously. There are currently over one hundred, some of which are animated. Currently, there are over one hundred. Although not all of them are particularly motivational, you may anticipate many third-party watch faces becoming available because the Zepp OS enables anybody to develop apps and watch faces. It is sufficient to have the ability to store nine different watch faces on the device simultaneously. Even though the animated watch faces appealed to my sense of aesthetics, in the end, I decided to go with the non-animated watch faces because they are less distracting.

Various developments have been made to the display, despite the fact that it maintains the same level of quality as previously. These are a direct outcome of the operating system’s improved ability to conserve electricity. According to Zepp Health, the visuals in GTR 3 are twice as smooth as they were in previous iterations. The transitions and screen effects really are pretty smooth, but I have no method of measuring whether or not this is indeed the case.

The GTR 3 Pro variant offers a more prominent display for customers who have expressed interest in purchasing one. The case size hasn’t changed much, but they’ve managed to reduce the size of the bezel so that they can squeeze a 1.45-inch display into the body. In addition to that, it features an elegant strap made of leather.

I put the Thunder Black edition of GTR 3 through its paces. There is also an edition called Moonlight Grey available for individuals looking for something more vibrant. The quick-release fluoroelastomer strap is 22 millimeters and adds an air of sophistication to the timepiece. It features a subtle ridge pattern that makes it simple to clean and keep in its overall condition. Because it is less restrictive than a conventional strap, this also helps reduce perspiration. The band is doing well, and it sounds good.

The final modification to the design addresses an issue with the vibration feedback. This is sixty percent more powerful than it was previously, and in addition to that, you may personalize the vibration according to your preferences for the various types of notifications.

The Engine Compartment

The water resistance at 5 ATM is still satisfactory. It makes going swimming or bathing without any concerns possible.

In line with the practices of other businesses, Zepp Health has advanced the sensor systems so that the device can now read its heart rate while the user is submerged in water. This is one of the advantages that come with having the most recent generation of the PPG BioTracker 3.0 engine built right into the watch. Additionally, it operates more quickly and precisely than it ever did before. A gyroscope, accelerometer, barometric altimeter, and geomagnetic sensor round out the remaining components of the circuitry.

Consequently, despite the fact that the array of sensors has not changed since the GTR 2 model, customers of the new generation will have improved nutrition and fitness tracking capabilities. Some of these issues were caused by updating the hardware, while others were brought on by installing a new operating system. But we’ll talk more about that in a bit.

There is still built-in support for satellite communication. However, whereas the prior version only supported GPS and GLONASS, the most recent iteration also incorporates GALILEO, Beidou, and QZSS into this list of capabilities. In my experience, I’ve discovered that the answer to this question does, in fact, make a difference. The speed at which connections are made and the precision with which they are tracked have significantly improved, in my experience.

The Amazfit watches continue to impress with their long battery lives, bringing us to this section’s final point. It is interesting to note that the battery capacity of the GTR 3 has been reduced by 21 mAh from its predecessor. However, the internal components and software have been updated to be more power-efficient, which has resulted in a seven-day increase in the amount of time that may pass between charges. When you turn on some of the power-saving settings, this period of time increases to more than a month. The battery life of a GPS device that records continuously for a total of 38 hours is good.

According to Zepp Health, the GTR 3 can operate on a single charge for approximately one week, even when it is put through heavy use. After putting this into practice, I discovered that it aligns with reality. I turned on all of the bells and whistles associated with tracking my fitness and health, with the exception of the always-on display, because I wanted to get the whole experience. This contains monitoring functions such as continuous SpO2 and auto heart rate monitoring every minute and comprehensive sleep tracking. Because of this, the watch’s battery life decreased by approximately 15 percent per day, equivalent to approximately one week between charges.

I have already touched on a handful of the distinctions that may be found between the GTR 3 Pro and non-Pro editions. You will need to purchase the more expensive Pro model in order to get it. Another significant shortcoming of GTR 3 is its lack of an integrated music storage system. In this regard, the watch is a step backward compared to GTR 2, which already incorporates this functionality into its design. The music transfer process is completed via the smartphone app and the WiFi connection on the watch, just as it was previously. As a result, the GTR 3 only supports connectivity via Bluetooth 5.1.

Review of the Amazfit GTR 3: Functionality - Significant Advancements Made in Comparison to the Previous Generation

Monitoring of One’s Physical Condition and Fitness

  • The device includes support for all essential activity tracking features.
  • Continuous and automatic monitoring of blood oxygen levels.
  • Watch provides daily statistics, while the mobile app provides long-term patterns.
  • Everything can be tailored to your specific needs.

When it comes to monitoring fitness, the Amazfit line of products has some very excellent capabilities. There is no use in going into the essentials in excessive detail, given that they are all present and function well.

On the GTR 3, navigating the various settings is relatively straightforward. They make use of an upgraded version of the operating system, which, despite its many improvements, is not that dissimilar in appearance to its predecessor.

You can navigate through the Quick Access Apps by swiping from right to left across the screen. Drag your finger down from the top of the screen to see the nine icons that make up the Control Center. To display the alerts, swipe up from the bottom of the screen. This, along with the vast majority of the other functions on the watch, can be adjusted to your specifications at any time. There are, in fact, so many different configuration choices that it is virtually impossible to choose just one.

The Quick Access Applications are a fantastic means of gaining information in a short amount of time. I thought it was incredibly cool that you could pick and choose which ones to show. For instance, some people wouldn’t want their workout status to be posted in that area. On the other hand, a person who runs frequently could favor that because it is a straightforward method for determining their Training Load, Recovery Time, and VO2Max. Several other applications can be added, such as Weather, PAI, Music, Alarm, Calendar, World Clock, and many others.

Shortcut Cards are another form of an oddity. You’ll see these appear when you slide from left to right on the home screen. This is just a list of cards that can be scrolled through and a quick method for searching through various information. Again, this is entirely adaptable to your needs.

The Zepp app had recently undergone a cosmetic refresh, which included the addition of information cards and a wellbeing tab, which renders it more appealing to people who want to utilize it. Most of the fitness and health information displayed on the wristwatch is for the previous twenty-four hours. You will need to download the iOS or Android app on your smartphone in order to view more extended trends.

You won’t need to open the app on your smartphone all that much when it comes to day-to-day use. The majority of the stats are displayed on the watch. Even more, I’ve seen that the GTR 3 is the only device that displays information on the number of stairs traversed. This feature has not yet been included in the mobile app for Zepp Health for some unknown reason.

Measurements of SpO2 that are done automatically are an advancement over the previous generation. Before, the only way to get there was on-demand, severely limiting their utility. Now, oxygen levels in the blood are monitored around the clock, which is a significant improvement. However, in order for this to operate, you will need to make sure that the Automatic Blood Oxygen Monitor is turned on. Either one can use the watch or the app on the user’s smartphone to complete the task.

It seems as though the readings are correct. For the most part, they fluctuated between 95 and 100 percent, with just a few days falling outside of that range. Because the chart in the app displays all of the measurements, the best thing to do is look at the daily number, which is often between 50 and 100 readings every day on average.

The statistics on sleep are likewise quite specific. On the GTR3, the Somnus Care sleep engine operates precisely as it did on the previous version. In addition to monitoring your nighttime numbers, it also keeps track of daytime naps that are longer than 20 minutes and the quality of your sleep breathing.

One tap measurement is one of the new features that can be found on GTR 3 watches. Your heart rate, SpO2, stress level, and breathing rate can all be measured simultaneously by the gadget thanks to the BioTracker 3.0 engine, and it does it in just forty-five seconds. Since this is for readings that can be requested at any time, I did not find much use for it. My preference is for none of this but instead all of it to be automatically tracked.

My GTR 3 was pre-installed with a very outdated version of the firmware when I first got it—because of this, keeping everything updated was quite challenging. The download would begin and then immediately halt several times. In the end, it took me a few days before I was finally able to upgrade the firmware on the watch correctly. But after that was completed, everything functioned without a hitch from that point on.

Because I had access to a significantly earlier iteration of the software, I was able to gain a better understanding of the function that is not currently available, specifically the ability to measure blood pressure. The answer is that I was able to use the watch to get accurate readings of my blood pressure. These were only available on-demand and were not performed automatically. In addition to that, they necessitated an initial calibration using a blood pressure cuff.

However, the blood pressure capability vanished once I changed the firmware on the device, which should not come as a surprise, considering that Zepp Health is presently awaiting regulatory certification for its PumpBeats blood pressure engine. Following the completion of CE and FCC certification, the device will activate the capability through the use of a firmware update. However, we have been advised that the process of acquiring regulatory permission is highly stringent and complicated. As a result, there are currently no known plans regarding when (or if) this could transpire.

When everything was taken into consideration, I was satisfied with the usefulness of the GTR 3’s health and fitness monitoring features. After getting through the initial hiccup that was caused by the firmware update, everything operated faultlessly and without a hiccup from that point on. Also, the concept that SpO2 is now automatically calculated around the clock was really convenient for me.

Keeping A Score in Sports

  • GPS is swift to connect and accurate.
  • The tracking of heart rate is approximately on target.
  • Compatibility with a wide variety of sporting modes.

At the press presentation Zepp Health held in October, the company announced that it had improved the satellite location chip. The GTR 3 has the capability to establish connections with five different satellite navigation systems, including GPS, GLONASS, Galileo, Beidou, and QZSS. Only the first two GTRs can communicate with the GTR 2. All of this seemed to point to a positive outcome.

The GPS chip was the source of most of my frustration with the first and second generations. When I went into a run, I never knew for sure how it would turn out. There were moments when it declined to link, and its accuracy degraded under certain circumstances. Now, I’m delighted to inform you that these problems do not appear to exist on GTR 3, which is excellent news.

The GTR 3 was not only able to find a satellite link significantly faster than the Garmin Forerunner 935 that was on my second forearm but also to provide more precise readings. This is something that I did not anticipate at all. The fact that I was able to test the watch in the densely populated urban regions of Central London makes this accomplishment all the more amazing.

When it came to tracking my runs, the heart rate monitor did a good job, but it was not nearly as remarkable as the satellite location. For instance, on a recent three-kilometer run, I experienced a maximum heart rate of 162 beats per minute and an average heart rate of 147 beats per minute. The Polar OH1 that I wore on my upper arm gave me a reading of 145 beats per minute on average and 155 beats per minute at its highest.

Therefore, there are still some inconsistencies, but it is reasonable to expect them from a heart rate monitor that is worn on the wrist. In my opinion, this is the primary challenge that needs to be overcome before the GTR can be considered a full-fledged sports watch. I hope that Zepp Health will integrate a way for GTR 4 users to link to external heart rate monitors in the near future.

I particularly liked the performance data of a Firstbeat-type that were available on both the band and the mobile application. You can find these metrics on both devices. VO2 max, Recovery Time, and Training Load are the components that make up these. You will also receive the Aerobic Training Effect and the Anaerobic Training Effect for each individual workout, in addition to a myriad of additional statistics.

The GTR 3 is more of a fitness watch than it is a sport watch, but it has a lot to offer in terms of monitoring your workouts and keeping track of your progress. Particularly in light of the fact that accurate satellite positioning is now possible.

The total amount of sports modes has increased to more than 150. (70 more than before). Therefore, there is something for each person there. There are eight of these that have auto-recognition capabilities. It’s noteworthy to note that if you set auto-recognition, the app will automatically switch on GPS tracking for outside activities when it detects that you are there.

Functions of Intelligence

  • The brand-new operating system is sleek and lightning-quick.
  • There are now only a handful of apps accessible for download and installation.
  • The watch is equipped with a microphone to support Amazon Alexa.

A discussion of the intelligent features of the Amazfit GTR 3 would not be complete without its inclusion in this review. As was previously stated, the GTR 3 is compatible with the subsequent version of the Zepp operating system. The previous software is ten times larger than this new version.

The latest operating system has been developed with round-the-clock monitoring of health as a primary consideration. This is the key differentiator between it and Wear OS and watchOS, both of which have an extensive structure factor and are therefore more demanding of resources.

The new operating system includes something called a Mini App Framework, and Zepp Health refers to it in that capacity. In essence, these are lightweight applications that have been specifically developed to function without any issues on the new platform. The wonderful thing is that anyone who has experience designing websites can create their own apps. This can be accomplished with the help of the company’s web-based development kit, which is built on the javascript programming language.

It is true that there isn’t much content that can be downloaded and installed right now. This is due to the fact that the framework for third-party developers is not yet in its final stage of operation.

On the other hand, you have the option of installing any one of several native applications. Every one of them can have its installation and removal customized to the user’s preferences. One example of this is the inclusion of a little app that prompts users to drink the recommended daily amount of water (1,200 ml). Zepp Health has produced other apps that include a calculator, alerts, suggestions for when you should be brushing your teeth, and other features. The long-term objective is to establish an environment that supports the development of thousands of apps.

This is unequivocally a step in the right direction. Will it also be available on other Amazfit-branded watches, such as the GTR 2? It is difficult to ascertain for certain because Zepp Health has not verified nor refuted the rumors that it will. In my opinion, that’s a very remote possibility.

The GTR 3 is equipped with an internal microphone compatible with both Amazon Alexa and standard voice commands. Since there is no speaker, the only way for you to get comments is through written text and visuals. You will need to link your Alexa profile through the Zepp mobile application before you can use it for the first time. This was not a problem at all. The Alexa software on the watch performs well, but I’ve found that it has only a limited amount of utility because it requires the companion smartphone app to be running in order to work. Notification functionality on the GTR 3 is likewise not nearly as robust as it could be.

The Conclusion of the Amazfit GTR 3 Review

Those looking for an activity monitoring watch will find that Zepp Health has developed a high-quality product. It is easy to see how GTR 3 is an advance over the previous generation, as the game offers a wide variety of appealing features.

The most fundamental aspects of health and fitness can be found there, such as a floor count and continuous monitoring of SpO2 levels. Monitoring of heart rate functions properly, and there is a good selection of performance indicators available on board. Connecting to GPS is now much faster and more accurate than it was previously. Integration of external heart rate trackers is the most critical component lacking from this watch for it to be considered a full-fledged sports watch.

The newest iteration of Zepp’s operating system has a visually similar layout to its predecessor, but it features improved functionality and a more streamlined, organized design. When you combine this with stunning hardware, the firm has a winning combination on its hands.

Naturally, the watch does not provide access to as many applications developed by third parties, nor does it provide the same level of notification customization as the Apple Watch or the Samsung Galaxy Watch. However, it has a reasonable price tag and a lengthy battery life, in addition to giving all of the necessary features for tracking one’s fitness and health. During the two weeks that I tested the Amazfit GTR 3, I found that my satisfaction with it increased with each additional use.

The catch is that there is no MP3 storage available to you. In this regard, the GTR 3 Pro might be considered the “straight successor” to the GTR 2. And there is no question that this is correct. There are some people who have no use for inbuilt storage for their audio. The removal of this feature from the GTR 3 model has the advantage of lowering the price to $179, which is the same as the price of the GTR 2. Those who need the capability will need to purchase the more expensive $229 Pro model. In exchange for this, however, they receive further modifications such as a temperature sensor, a larger display of 1.45 inches, and a speaker capable of supporting smartphone calls.
