Review Overview
Amazfit GTR 3 offers a compelling set of hardware and features for a smartwatch under $180. I'm quite impressed with its long-lasting battery and vibrant display. There are no compromises on the fitness and health tracking side of things. That being said, Amazfit needs to work on its software. GTS 3, on the other hand, has pretty much everything that GTR 3 has but comes with a square display and a less-impressive battery life.

Readings can get inaccurate at times
However, I have to tell you that I’ve encountered some inaccuracies with SpO2 monitoring on the Amazfit GTR 3 and GTS 3 during the review period. On a few occasions, it showed really low SpO2 readings which scared me a lot. So to cross-check, I used an oximeter which gave a 98% SpO2 reading instead. This has happened only 2-3 times with me, but I just thought you guys should know that. The watch also brings a PAI score which is calculated based on the physical intensity of activities. The more cardiorespiratory exercises you do, the more your weekly PAI score is. As you can see, my PAI score is really low, meaning my exercises aren’t as physically strenuous as they should be.Over 150 exercise modes
Alright, in terms of fitness, the GTR 3 does not disappoint though. You get more than 150 exercise modes here, including the basic ones like indoor/outdoor running, walking, cycling, and swimming, to hula hooping, skiing, frisbee, kite flying, etc. Now, I am not so much of a fitness freak, but I do go for a run every now and then. During those times, I would turn on the built-in GPS on the watch that works really great, by the way. You can also adjust the accuracy of the navigation system to prolong battery backup via the settings. But do note that it takes some time to lock the GPS signal when initially turning it on. On a related note, the automatic workout detection feature leaves little to complain about as well. It’s not as good as what I have experienced with the Galaxy Watch 4, but it’s not that bad either. As I mentioned earlier, I go for outdoor runs often and this watch would recognize it after 5-6 minutes into the workout.Proprietary Zepp OS platform
Moving on, the GTR 3 runs on Zepp OS which is Amazfit’s proprietary operating system for its smartwatches. Likewise, all your workout and health-related data syncs with the Zepp app, which is available on both Android and iOS platforms. While the app itself is not the most intuitive, I’d say it gets the job done. It is very simple to use which is something I appreciate. Having said that, just like the Huawei Watch GT 3, you don’t get a lot of third-party app support here. There are a few options for different apps but personally, I don’t find them that useful. Anyway, it has a pretty decent selection of watch faces though and I am totally obsessed with this cat watch face, because, well, I am obsessed with cats.Can't take calls
Also, the GTR 3 has a built-in microphone, but since it’s not complemented by a speaker, you cannot make or receive calls here—although it does support call notifications. The Amazfit GTR 3 Pro, which is a slightly more expensive version of this watch, can indeed make/receive calls. So if that is important to you, I’d suggest you go for the “Pro” version instead. One incredibly annoying—and possibly a deal-breaking—bug I’ve had with the GTR 3 is that it would just shut down and restart on its own for no reason. This has been happening from the day I started using it and even after 2 updates I’ve received so far, the issue is still not fixed. Hopefully, Amazfit will look into this ASAP! On the other hand, the watch comes with Amazon Alexa as well as offline voice assistant support. As a result, you can give voice commands like "start workout", "brightness up"—for hands-free control. This feature is not an absolute necessity, but it does make operating the watch a little simpler. Plus, it’s pretty fun to use as well! Finally, something that the GTR 3 utterly nails is the battery life.Battery

Amazfit GTR 3, GTS 3 Review: Conclusion
Summarizing my experience with the Amazfit GTR 3, well it has been bitter-sweet. On one hand, I really appreciate its battery life, the amazing display—whereas it is competent with the health and fitness-related stuff with great accuracy. But at the same time, the persistent software bugs have made my experience somewhat bitter. However, the few software-related issues I discussed earlier are something that can be fixed with updates, so I wouldn’t worry about it too much. Overall, the Amazfit GTR 3 does everything a good smartwatch should do. And looking at its relatively cheaper price tag, this sure seems like a worthy option against the more expensive alternatives. If you prefer square dials, Amazfit GTS 3 has almost the same experience but with less impressive battery life.- Watch our video review of Amazfit GTR 3, GTS 3.
