Review: Incredible watch! Does it All! I can't say enough about it! - This is my third Amazfit watch. I started with the Bip 3, moved up to the original GTR (Great looking watch with great features - was my favorite!). I hesitated to go for the GTR 2 or 3 simply because the GTR was such a great watch - super good battery life, accurate readings, etc. But when the GTR 4 came out, I decided it was time for an upgrade. I've been so pleased with this watch. It's such a step up from my other watches. I love how I can customize my swipe left or right (with a continuous loop, no less) to have my favorite functions - Top widgets, steps, heart rate, Blood O2, music, compass (with altimeter and barometer as well), weather, and the shortcut cards that allow me to add even more functionality at my wrist (Calendar, upcoming alarm, countdown, stopwatch, one-tap measuring, sleep, PAI). I don't use Alexa, but I have used the offline voice control, which works pretty well; but with all the apps right there, I prefer to swipe. I love the membership card feature (bar codes from cards for grocery stores, pharmacy, Red Cross, etc.) and I always feel very "techy" when I scan myself in at the platelet center or the self-checkout. The weather app is accurate with a five-day forecast, and I love the sun and moon feature (helpful for hiking to know the sunrise and sunset times, and to know if I'll have any moonlight at night). The phone app is awesome. It's always nice to take phone calls from my bride when I'm at work or hiking without having to take out my phone. The sound on my end is great and she says the microphone sounds better than my phone! I can use the number pad or my contact list to make calls as well. I also love being able to respond to texts (I get the full message, by the way, not just a line or two) with one of 10 pre-set responses, or even emojis. It's more than a novelty and I really enjoy being able to use it. The workouts are more than I will ever use. Mostly I use walking, climbing (hiking), biking, strength training, indoor biking, and a few others. I wish they had some workouts for when I'm out in the yard raking leaves or chopping wood, but I find other exercises that serve as equivalents. I love all the information the app gives me about workout duration, calories burned recovery time, etc., as well as the little "Hoorays!" for achieving goals, and the suggestions, reminders, and coaching it gives as well. As far as the heart rate, blood 02, and steps, I find those to be very accurate (My vitals are checked twice a month when I give platelets.), so it gives me an good overall picture of my health. The sleep tracking is better than before. My other watches would only measure sleep at night, but since I work nights and sleep during the day, it wasn't as helpful. The GTR 4 measures "naps" so I'm getting a more accurate picture of my sleep. And on the weekends when I switch to sleeping at night, the readings give me a very good general sense of my sleep patterns, and I'm happy with that. What more can I say? There's a calculator, flashlight (decent for what it is), stopwatch, alarms, find my phone, camera remote, stress readings, etc. I love the one-tap measuring. I just hit that button and in 45 seconds get a good overall picture of my health. The music player app works well (a remote control for your phone). I haven't used the music download feature, because I would rather save the memory (lots of memory, by the way) for map data, and I always have my phone with me, so having music on the watch would be redundant for me; but it's a great feature nonetheless. I've also downloaded a bunch of apps from their proprietary app store - games, tip calculators, unit converters, and even navigation apps. No, I don't have detailed topo maps for the watch for hiking, but it does give me some basic functionality in that regard. My hiking, biking, and walking workouts are sent to the app and displayed on my phone. There are a ton of great watch faces, many of which can be customized, all ranging from traditional analog to techy digital styles. Battery life is pretty decent. Even with frequent workouts using GPS, I average about two weeks before I have to charge the watch. In fact, I often forget about it until the 10 percent reminder comes on. The watch is stylish and good-looking, but still tough, well-made, and pretty much perfect for my needs. The buttons and touch screen are very responsive (the main button also rotates to move through the app drawer), the vibration is enough to wake me up from sleeping, I don't go crazy with outdoor workouts, so this is right for my needs. I know Amazfit makes more rugged watches for real adventurers, but they don't have all the features the GTR 4 has, so I'm happy I chose this watch. The Zepp app has gotten even better and has so much information and functionality. I found a lot of helpful videos online to help me with navigating the app; but, in general, I picked up on it pretty quickly, and have used it to customize the watch so it works well for me. Overall, I'm so happy I purchased this watch. Normally, I don't gush this much over a product, but I'm just so please with it. Amazfit makes really good watches that work well, last, and provide so much for the price point (way more, in fact). I highly recommend this product and Amazfit in general. I hope this review has been helpful.
Review: A competent, attractive fitness watch. - Update: I’ve now owned this watch for 3 months. Still doing great. Not a scratch on the face, and I’m pretty rough on my watches. Battery holding strong. I’ve become more attached to this watch than I ever was ti my Apple Watch. Very happy with my purchase. Original review: Let me preface my review with the fact that I’m a iPhone user. I’ve had most revisions of the Apple Watch and I’m not a fan. I think they’re blocky, poorly designed and not masculine. So I’ve tried many different watches over the years with varying success. I loved the Samsung watches until they became incompatible with IOS but their battery life was terrible. So I decided to give this watch a try. I was considering buying their more expensive military fitness watch for $400, but after comparing features and aesthetics, it was hard to justify the extra expense. So let’s talk about this watch. First, it’s shockingly light and has a really big, bright watch face. It’s also very thin. It fits very comfortably on my wrist. I wear my watch upside down so the fact is on the underside of my wrist. As such, the face is much more prone to scratches. I’m happy to report that after more than a month of use, not a single scratch is visible. The watch has a protruding dial button as well as a recessed button, in addition to the touchscreen. I rarely use the recessed button but the crown button is handy, but I wish it didn’t protrude as much. Sometimes when I curl my wrist, it powered off the watch. I’ve made small adjustments when I wear it, and it seeks to have resolved that issue. The watch face is very bright and incredibly responsive. The battery is astonishing. Ilas you set up the watch, it lets you know if you’re selecting an option that drains the battery faster. I’m a power user, so I pretty much have everything maxed out and I still get about 6 days battery life. I was also concerned, as per reviews, that the readings are inaccurate, especially the sleep readings. I’ve found them to be quite accurate. I spent two days with my Apple Watch on one wrist and this watch on the other. The readings were within 1% consistently. I’m pretty sure they’ve resolved many of the issues via upgrades to the watch. I feel this watch gives me much more usable information than does the Apple Watch and I really like the companion app. It is very intuitive and works well with my phone. Overall I’m very happy with this watch. Not only is it a steal for the price, I would choose this over the Apple Watch. Be aware That you cannot receive iMessages on this device. It’s a restriction from Apple and not the fault of this watch. As long as you connect this via Bluetooth, you can carry out most functions between your phone and watch that you would normally expect. My only complaint is I purchased the version with brown Watch band. The band is terrible and cheap. A poor choice considering how nice the watch is. Fortunately there are several cheap alternatives in desertcart so I won’t complain too much. Just be aware you’ll want a different band. You really won’t go wrong buying this watch for features, quality, functionality, aesthetics and price.

## Questions & Answers

**Q: When you delete an face watch how do you reset the storage space to see the actual storage capacity?**
A: There is a App you can download in the smartphone app that measures storage space

**Q: Are the sensors for blood oxygen etc. upgraded in this watch from the previous version?**
A: Yes, The Amazfit GTR 4 debuts the new BioTrackerTM 4.0 PPG biometric sensor. Enhanced to 2LED, the sensor collects 33% more data and is more accurate than the previous generation, thanks to the ultra-thin 0.4mm glass base.
This sensor, combined with the watch's upgraded heart rate tracking algorithm, greatly reduces potential signal interference caused by arm movement during exercise, for heart rate tracking that almost reaches the level of heart rate belts.

**Q: Can you reply to messages and phone calls?**
A: This answer applies to the new Gtr 4 MINI. I don't know how they can have reviews and answers from months ago for a watch version that just came out March, 2023. This GTR 4 Mini is brand new so MY answer applies to this new version. You can also go into the Zepp app and add or delete messages. I've already done that since most of the prewritten messages didn't apply to my situations.

**Q: The gtr 3 has a compass, is there one in the gtr 4?**
A: Yes the GTR 4 also has a compass

### ⭐⭐⭐⭐⭐ Very full-featured, works amazingly well, stunning battery life
*by A***Y on April 15, 2024*

I have been exceptionally impressed with this watch. All the advertised features work as promised (rare!) and the app is easy to use with almost all the data collected, processed, and displayed in very thoughtful and intuitive ways. And it collects so much useful data - far more than most fitness trackers. Battery life is unreal - I collect every available metric every 5 minutes 24 hours a day, consult it dozens a times each day, have the screen on full-time during all workouts, and it still lasts a week+ between charges. I scanned all my grocery-store, gym, etc. membership cards into the app and now I don't have to carry any of them with me - they are all on my wrist. It has made a huge difference in my fitness efforts due to the motivation that comes from being able to precisely track what you accomplish. There are some small issues that I would like to see improved: The app features annoying adds for add-on services (like more detailed sleep analysis) that require subscriptions. You can't turn them off either - they just come right back. It also includes an app store where you can buy watch faces and apps for a few dollars each. This is frustrating because almost all of them are available to download free from miwatchfaces(dot)com - they are reselling other people's free work and charging for it. My only other gripe is that the only Heart Rate Variability measurement function is a metric called "stress" with an arbitrary number that is provided after every measurement. This makes it difficult to interpret for one of the most useful ways of using HRV which is identifying when you are coming down sick a few days before you actually get symptoms. Also, why does that app consume so much background data??? But don't get me wrong, there are very few purchases I have made this year that have been as positively impactful and valuable. This is a great watch.
